Beschreibung

Country Cottage Conservation is essential reading for everyone who loves rural cottages. From simple DIY redecoration to employing architects and builders to tackle significant repairs, this book is full of helpful information. The author explains how cottage owners are able to protect and enhance their investment, and discusses various repair and redecoration options and their consequences. The charm and long life of a traditional cottage comes from over a thousand years of building tradition that was almost forgotten in the twentieth century. Modern materials and techniques are often expensively inappropriate, as they can conflict with the buildings' inbuilt defence mechanisms or make cottages look too modern, yet it is still possible to repair a cottage economically with traditional methods and natural materials that work in harmony with the original construction. The author also considers what may be done to redress the balance where inappropriate work has previously been carried out, so as to restore some of the original performance to the cottage and help preserve its charm, and value, for the future. Essential reading for everyone who loves country cotttages and invaluable for those who want to maintain and repair their property in a sympathetic and sustainable way, it is also superbly illustrated with 239 colour photographs.

Introduction

WHAT THIS BOOK IS ABOUT

The information

This book sets out practical information that can help owners to keep their cottages viable and attractive. It aims to help bridge the information gap – between recognizing the need for action and deciding on what action to take – by providing some understanding of the special nature of cottages and how repairs and redecorations may affect them for good or ill. This information can be of help to owners whether they propose to carry out work themselves or engage others to do it for them. Cottages were designed cleverly to keep themselves intact despite dampness and movement. This technical performance is due to the way in which they were designed to use natural, sustainable materials, and it was also linked to the way in which people lived in their cottages. The visual appeal of cottages follows naturally from the authentic materials and their technical design. This book explains how some of this original look and function might be restored and preserved for the future.

Identifying the problems faced now

This book also looks at the condition in which most cottages have arrived in the twenty-first century. In addition to the problems of time and wear, cottages have not been served particularly well by many of the industrialized products and building methods of the twentieth century that have been, mainly innocently, applied to them. Most country cottages have been through several rounds of refurbishment since rural workers began to leave them a century ago. Books published since the 1950s have often tended to address bringing cottages up to contemporary standards of comfort, ‘doing them up’, frequently involving extreme rebuilding in the twentieth-century manner.

But the problems faced by a new owner today are much more likely to be about whether those twentieth-century repairs are mismatched with the original construction, and failing in some way, and whether recent refurbishments have also robbed the cottage of the character that once made it so attractive. What can be left of a cottage in many cases is not so much cottage, more a poor imitation of a modern house.

HOW THIS BOOK IS ORGANIZED

The chapters are organized within five sections, each identified by coloured pages:

The first section, ‘OLD AND WISE – A cottage is not a modern house’, introduces some essential information about taking on a cottage today and where help can be found in assessing a property for purchase or repair. It also explains in a straightforward way the big differences between a cottage and a modern house in terms of how damp and movement is managed. The persistent and continuing misunderstanding of these important qualities by owners, builders and professionals has arguably been responsible for the advancement of decay in countless cottages during much of the last century – so it’s worth knowing before considering new work on any cottage.

The second section, ‘THE WAY WE WERE – Cottages as they were built’, examines some of the more common constructions used in cottage building, including some principal variations of materials used for roofs, walls, doors and windows as found in different regions of Britain. This section also looks at how those traditional constructions emerged from the necessity to make use of what the countryside was able to provide, and the limitations imposed by lack of transport and machinery at the time. These intrinsically sustainable methods and materials should, nowadays, also be of use, informing modern environmentally conscious design in new housing.

The fourth section, ‘IN THE YEAR 2525 – Preparing for the future’, imagines the cottage in the future. Cottages can offer practical lessons to the twenty-first century on how to build durable, sustainable and beautiful low-impact dwellings from what was once immediately available, all without using up fossil fuels or industrial quantities of energy. Cottages were highly sustainable when their occupants had no choice but to live sustainably themselves. But now we have become used to living unsustainably, and because most people in Britain are likely to continue to feel that they deserve more than nineteenth-century levels of comfort, this section looks at how we can try to match our own unsustainable needs with a cottage’s sustainable heritage – including insulating cottages appropriately.

Section three is ‘THE PRESENT – And what the twentieth century did’. For the best part of a hundred years now, most cottages have not been used or repaired in the ways that were originally intended. In many cases cottages were cast off as slums and then perhaps taken on by wealthier people to use as holiday homes; some have survived as permanent homes, most have been ‘modernized’. Like many a collectable antique item or classic vehicle, they have passed through a period of being underestimated before they emerged as desirable survivors. This section looks at appropriate maintenance and repairs, and also what might be done to redress past works that may have been inappropriate.

Finally section five, ‘STYLE COUNSEL – Keeping the look alive’, offers some ideas on presentation, inside and out. This is not intended to impose any particular ‘period lifestyle’ but rather to highlight how easy it is to over-dress a cottage and to lose the simplicity that is, after all, the essence of a cottage’s attraction. This section also examines a few of the practical problems often faced, including getting a fireplace to work properly, extending a cottage sensitively, and incorporating kitchens and bathrooms.

ABOUT TO BUY A COTTAGE?

Cottages are often less convenient to live in and more expensive to buy than the equivalent modern house, so there is something that puts them into a similar category to antiques and classic cars. The owners of those items happily accept some limitations in performance in return for the interest they give and the attention they attract. Those owners also tend to take great care to use only authentic materials in their repair. The same is reasonable for a cottage – but the message that one day a cottage could be worth less if it has been poorly ‘modernized’ has to fight to be heard above the clamour of sales pitches for home improvement products. Owning a cottage can present an opportunity to engage with a different sector of the economy, one that is involved with natural materials and ancient crafts.

THEN, WHAT IS A COTTAGE?

This book assumes that a country cottage was built for rural workers any time up to the modern period, when modern industrialized building materials took over. This ‘modern period’ was a result of the nineteenth-century’s industrial revolution, but there were still country cottages being put up with basically mediaeval technology for some time after, perhaps as late as the 1930s. Estate agents sometimes like to extend the term ‘cottage’ to urban terraces and ‘artisans’ dwellings’, and indeed some of those built in the late nineteenth century and early twentieth will owe much more to the traditional construction that this book is concerned with, than to the newer conventional ‘modern house’ methods.

It took some time for industrialized materials to displace old habits. Those late Victorian, Edwardian and later urban ‘cottages’ are, however, likely to exhibit ‘hybrid’ constructions – blends of ancient and modern. In a similar way many ‘genuine’ country cottages will have become hybrids in that they have been extensively altered in the modern period. But even in those cases an understanding of traditional building ideas is still very useful in making decisions on future repairs.

Country cottages may be grouped in a hamlet…

… or equally in a village or country town and then, when do they become houses?

Perhaps the typical country cottage stands alone in the countryside. Its accommodation may often have been tied to a particular job of work …

… or cottages may have served other needs such as almshouses; sometimes a larger house was subdivided into cottages, or the other way round, and back again.

The nineteenth century produced the ‘cottage orné’, an elaborate and probably quite expensively embellished version motivated either by a desire to improve the lot of tenants or to make a country estate look more jolly. By the end of the cottage era, cottages were more often designed by draughtsmen than by the ‘builder’s eye’, and their technology and function were often assimilated into the council house.

RESPECT FOR THE PAST

Gone …

Too much has been done to most cottages to ‘turn back the clock’ and recreate an authentic restoration of their past, either in technical function or in visual appearance. A full restoration would anyway be more appropriate to a museum because it would have to reflect the life of people living perhaps six to a bedroom with one main wood fire that had to be tended all day, every day. Some of those folk lived in the shadow of perpetual fear of eviction, disease, starvation and infant mortality – the echoes of that way of life are still remembered by some. Needless to say there were no bathrooms, no indoor WCs, no electricity, no central heating and often no piped water. Cottagers were poor, way beyond the scope of modern British definitions, and cottage life itself was nearly drawing to an end before most were allowed any political voice or offered any significant state safety net.

… But not forgotten

We may have a romantic vision of cheery ploughmen and rosy-cheeked milkmaids, some of whom may actually have been lucky enough to have enjoyed an uncomplicated life under the paternalistic care of others. But cottage dwellers were, in practice, slaves to their condition, and their labour in the countryside provided essential services, such as putting food on the tables of the nation. The simple, frugal and obedient way of life they were required to adopt has inspired some onlookers to label their condition as noble and romantic; others considered them exploited.

A rare sight now, cottages no longer inhabited but still in their original form. It was the availability of many so-called ‘slum’ dwellings in similar circumstances that fuelled the country cottage boom of the mid-twentieth century, helped by government grants. Conservation knowledge was rarely applied then, and many such cottages went on to become, literally, modernized.

Nowadays untouched cottages are considerably rarer, and the more likely situation is a cottage that was modernized years ago but which would now, once again, be considered in need of attention. This book hopes to help bring cottages together with a more sympathetic kind of attention this time round.

So if we do examine ways in which to ‘restore the past’, then perhaps it should be with respect for the memory of past occupants, their fragile lives and their building skills. In looking after cottages we can do this by preserving the old materials and artefacts that survive, and resisting the temptation to apply a sugary varnish to the events they record. The smallest evidence of the real past can be beautiful, human and touching enough.

THE FUTURE

Gone …

There is a common thread between the emptying of rural labour from cottages and the refilling of those same cottages by commuters or holidaymakers, and that common thread is mechanized transport. As the steam traction engines and diesel tractors came to the countryside, so the manual labour and horse-power began to be shown out.

Then steam trains, petrol-powered cars and buses allowed people to work in the towns and live or play in the countryside. Ironically some of the new ‘townie’ incomers will have been descended from the agricultural workers who previously had to leave the countryside, and this perhaps accounts for the nostalgia that surrounds cottages.

… But coming back?

But it is becoming possible that, in the near future, fossil-fuel depletion could turn back the clock. Even if we do not see a reduction in the use of powered vehicles, we are increasingly likely to have to create our new homes almost entirely sustainably, as our forbears did, and that means with much less reliance on imported and highly processed materials.

This book examines some of the lessons from inherently sustainable traditional building materials and techniques that were used for centuries before our dependence upon fossil fuels. These ancient ideas are already being dusted off in preparation for being re-adopted for sustainable building in the future, and these old traditions of sustainable building have even more to offer than most people perhaps yet suspect. The future may not consist of the exciting silver things on stilts that we were promised in the 1960s but, instead, revived versions of the cottages that the 1960s saw being demolished.

Using proven and reliable resources

The sustainable and naturally abundant materials that have been used to build cottages were understood for a thousand years, the traditions handed down through practical apprenticeship. The modern age almost wiped out that knowledge. Many are now pioneering an alternative sustainable construction using ‘waste’ materials such as used tyres and straw bales, which is admirable. But those materials are arguably only available as by-products of an industrialized system of living, farming and transport that may well have to change soon. The traditional materials used in cottages were well understood, better than our conventional modern materials, and better also than the new ‘recycled’ materials. There was simply more time to get to know them over a millennium. There is no need to wonder how well traditional construction may perform over time – every surviving cottage is evidence of what can be achieved using what the natural world delivered, without waste. All we have to do to ensure a continued supply of natural materials is to look after the natural world.

Preserving interest: preserving value

Apart from what cottages can teach us to help cope with the future, they are also records of the past. This may be a novel idea to those who are more used to new houses and who have wanted to make them their own and alter them to take account of new fashions. But the reason that a cottage may well cost more than a new house is that it is, in effect, an antique – and a unique one at that. Alter or modernize an antique and its value generally diminishes.

Old country cottages may now have found a new type of owner, but will there be a new generation of cottages built in the countryside for farming use again, using some of the same sustainable materials?

A small example of the frailty of the past: the burn mark made by a candle or taper where it was routinely attached to a post hundreds of years ago; a coat of varnish would obscure it, or a coat of paint, and it might be lost forever.

The corrugated iron porch may be practical rather than elegant but it is a reflection of the reality of cottage life until recently; the smartened version of the porch next door has not been over-elaborated, and seems commendably restrained.

So this book addresses the ideas of repairing and retaining original fabric rather than just renewing something when it needs attention. A related idea is that of ‘reversibility’, which here means that, in order not to devalue the antique nature of the cottage, any necessary changes should be made, if at all possible, so that they can be completely undone in the future without leaving a permanent scar on the cottage.

SECTION ONE

OLD AND WISE

A cottage is not a modern house

Cottages were the simplest of dwellings, which might originally have been built straight on to trampled earth and using scraps of wood, mud, straw, twigs, blood, hair and dung. Despite the primitive farmyard flavour of that list, all the ingredients would have been assembled and used to best advantage in accordance with a thousand years of word-of-mouth research and development. Although it lacked our modern calculations, certificates and official approvals, a cottage had to be every bit as technically integrated a product as the most modern building is today. But much of that building skill and understanding was wiped out by the social upheaval and technological change following an industrial revolution and two world wars.

When the twentieth century devised new building materials, the well tried ways of building with what nature provided began to be forgotten. Newer substitutes sometimes offered apparently enhanced performance, sometimes needing less time or less skill to use. This new building technology obviously works well on its own and has provided clean and efficient homes for around a century. But modern building technology functions in some very different ways to traditional sustainable rural building technology, and mixing the two technologies in the same building can cause one or both to fail. Acceptance of this came, through bitter experience, late last century – yet some find that experience hard to accept, and will still try to force the two technologies together.

The simple materials that our ancestors spent so long refining and understanding were also, in our modern terms, highly sustainable and largely natural materials. In a world that pre-dated the internal combustion engine and electricity, low energy living was a necessity and not a lifestyle choice. They had to be good at it to survive. Recycling (and avoidance of waste in the first place) was also necessarily second nature. Their buildings have been proved capable of very long life – much longer than modern homes dare to claim. Cottages were once designed to be heated, not by imported fossil fuels but by what nature provided locally – wood; and wood we now recognize as a ‘carbon-neutral’ fuel in our world that is threatened by climate change.

So a cottage has real answers to our present building crisis: highly sustainable, long life, natural materials, minimal transport, renewable energy and carbon-neutral heating. Yet despite these clear virtues, old housing has long been under threat of being swept away to be replaced by something flimsier made from components that come from factories hundreds of miles away. Cottages can teach us so much about how we might adapt to live responsibly with our planet in the future. If only we would stop trying to force them to conform to last century’s outdated and unsustainable ways. But that is for Section Four, first …

The chapters in this first section introduce some differences between cottages and modern homes that can affect the way they are lived in and looked after, and which it would be useful for any prospective cottage owner to understand before crossing the threshold:

Chapter 1: Thinking of Living the Dream? – Some perspectives on the idyll

Chapter 2: The Professionals – The right help when needed

Chapter 3: Don’t Bring Me Down – Traditional management of movement in cottages

Chapter 4: The Air that I Breathe – Traditional management of damp in cottages

CHAPTER ONE

Thinking of Living the Dream?

Some perspectives on the idyll

THE EMOTIONAL SIDE

Many of us are attracted to a country cottage in much the same way that people are attracted to chocolate: it is an in-built yearning that was implanted in us very early in our lives. So it is probably no accident that chocolate boxes have had a long history of being adorned with pictures of cottages. But chocolate is a craving that is quite cheap to satisfy, while cottages are more expensive.

If already gripped by a desire to live in a cottage it can be difficult to step back and analyse what makes the idea attractive, but as there is a lot of money and happiness at stake, it’s worth making the effort. The appeal of a cottage is often visual, so we can try an experiment with that side of things first. Take a good look at a real cottage: for this to be as scientific as possible, find a cottage that is close to its original appearance. (A village or holiday cottage owned and maintained by one of the National Trust charities, one of the national conservation organizations, or perhaps a large country estate might be good places to look – the majority of cottages found in country lanes and in print are, like many of the examples photographed in this book, already well in the grip of the twentieth century.)

Now take a good look at the cottage pictured. No two examples in the country will be the same because the British Isles have a rich variety of landscapes and geology, from which cottage building materials came. But despite regional differences there is every chance that a good example from anywhere in the country will display many of these characteristics:

The walls and roof may appear irregular, or downright ‘wonky’.

The doors and windows may be familiar-looking, but not standard designs.

There may be evidence of charmingly crude, but effective, hand-made repairs.

Surfaces, even when soundly decorated, may appear uneven or blemished.

There may be features left over from the past that make no current sense.

Much of the character of a cottage is linked to evidence of its original purpose and condition, so the less this is overlaid with suburban neatness, the more of a cottage it will appear.

Cross-dressing: the use of modern materials for repair and decoration can now give cottages an industrial age veneer. At the same time, new houses are deliberately being built to try to look pre-industrial.

The reflections from the window in the red wall (above) show the contrast between older, slightly ‘crinkly’ glass, bottom left pane, and more perfect later glass. The straw-coloured wall (below) shows that an informal ‘imperfect’ quality also gives character to walls. Much cottage character is due to subtle visual imperfections and irregularities; iron those out and some charm evaporates.

Now picture an image of this cottage on a computer screen about to be manipulated by some software – by which the outlines are first straightened, the doors and windows are replaced with modern standard patterns, the old repairs are swept away, the surfaces are made much more uniform in colour and texture, and all the old superfluous features are done away with. The result the computer screen shows might be cleaner looking and more rational, but would it still look like a cottage?

The real life version of the imaginary computer exercise described above is almost precisely what so many cottage owners have actually done to their homes, and at great financial cost. Not at all because they are mad or vandals, and no one would doubt that they love their homes, but because they have been drawn into the modern-home way of looking at things that promotes straight, clean, tidy and new. Nothing wrong with those things in the right places, they just don’t seem very ‘cottage’. Maybe they did not know that there are other ways of going about repairs and redecorations that can preserve character. Or maybe they would have been happier with a new house instead. A lot of people are put off real cottages by some of the ‘down sides’ sometimes associated with them:

No off-street parking, or difficult access.

Curious boundary arrangements, including ‘flying freeholds’ and remote gardens.

Poor acoustic insulation between attached properties.

Necessity to negotiate some routine repairs and redecorations with neighbours who are under the same roof.

Inability to totally exclude unwelcome wildlife, such as rats, mice, birds, insects and spiders, from old walls, floors and roofs.

Poor thermal insulation that does not sit happily with current heating methods, and which might be awkward to improve without destroying the character or fabric of the cottage – and therefore necessitates lower indoor temperatures.

These ‘deficiencies’ are not so much due to age or deterioration, but more to do with the modern expectations we have learnt from modern houses and the modern levels of comfort that we demand. In other words they are not so much a result of a cottage being old and worn out, it is because we are new, we have become more fastidious, and we are trying to make cottages do different tricks to the ones they are good at.

But there is one last possible drawback with cottages that demonstrates how hearts can rule heads:

A cottage has frequently tended to cost more than a modern house offering similar accommodation.

This should, even for the non-romantic, be a persuasive argument for keeping their investment looking more like a cottage and less like a modern house.

Just old-fashioned

There is a lot of debate about whether new buildings should be styled according to traditional values or be entirely free from past constraints. Fair enough when it comes to the style of a new large public building, but when people have decided that they want an old country cottage there seems little question that what is wanted is the past, and in spadefuls.

Horse sense

If the modern owners of an old cottage also had a horse, they wouldn’t dream of feeding it diesel instead of hay; nevertheless, many will happily force feed their cottage on modern building and decoration materials that are potentially just as ridiculously inappropriate. A mis-fuelled horse may fall over and die quite quickly, but a mis-decorated house can continue to stand and even look reasonably sound – yet within its walls, softening and decay could be taking hold.

THE TECHNICAL SIDE

The cottages that people might now dream of living in would have been built in the days when horses were still everyday transport: a very different age. Nowadays, a small modern house might even try to look a little like an old cottage, if a little smoother and straighter. It might have similar-looking bricks, timber, paint and render. But if this modern small house is built in the conventional modern way, there the similarity ends – because modern houses, and many of their materials (including the bricks, timber, paint and render), can perform entirely differently to olden traditional construction in several very important ways. And so a cottage needs to be looked after in a different way to a modern house – simple enough.

The problem is that people have been seduced into applying modern maintenance methods to their cottages, and unwittingly they have created problems involving dampness and decay. So they have had to go on and spend more money rectifying those problems. The time has now come when a lot more is understood about how old buildings worked, and how cleverly they coped with ageing. Cottages can’t be bludgeoned into being new buildings, and it can often be better for them, their owners and their bank balances, if they all decide to work in the same way – the way the original builders intended. Those men and women had, after all, been building on a thousand years of ‘trial and error’ experience in their locality. Our modern building regulations have been around for only a twentieth of that time, during which they have had to be revised as problems have come to light – and more will no doubt have to be readdressed. Cottages were built on a more mature set of ‘rules’ that are worth trying to understand.

So it is not simply judgements about visual quality that make conservation architects, planners and historians unhappy when they see some modern materials and modern building practices applied to old buildings: there may be sound practical reasons why some of these innovations could be unsatisfactory or why they might cause serious problems in the future. The modern cottage dweller needs to be aware of them.

Cottages breathe, or at least they should

House building in the pre-industrial world (the changeover happened some time between the late nineteenth century up until several decades into the twentieth) had to rely on what is called ‘breathable’ construction rather than the modern practice of near-total water-tightness. This was simply because there were very, very, few traditional building materials that were reliably totally watertight in long-term use. So buildings were assembled to shed what rainwater they could, while other sources of damp, such as ground dampness and internal condensation, were dealt with by the constant and unavoidable ventilation that fed open fires and ranges. Walls and floors would have been in a constant cycle of wetting and drying, and they relied on the drying power of the sun and wind externally, and a permanent fire and its draughts internally.

Like an old-fashioned woollen overcoat, an old cottage might have kept its contents dry in a shower by a combination of deflecting most, and soaking up some, rainwater, but all the time letting out the wearer’s perspiration. With luck it stopped raining before the cottage walls, or our overcoat, were saturated and began actually to admit water. Once the rain did stop, then like the coat, the walls would dry out in the sun and wind, and in that way mould and rot were less able to take hold.

But cottage owners need to understand that applying a coat of modern waterproof paint or render to an old cottage will have similar results to trading in the woollen overcoat for a bin liner: pretty good for the first fifteen minutes, pretty dire after an hour or two when the inside is running with sweat. In terms of a cottage this sweat translates into condensation and dampness that becomes trapped inside the building materials, and that can cause decay.

The modern-built house can take advantage of modern waterproof construction and finishes that should have been assembled within an integrated design, soundly joined together to banish all damp and wet. The insides of things, we hope, never get wet in modern construction. But in a cottage they do, and it is too late and too costly to rebuild them so that they don’t (and if we did they would no longer be cottages). The cottage with just a few modern finishes applied here and there would still be taking in water in some places, yet unable to get it to dry out completely through the waterproof bits. Imagine what condition parts of your body would be in if wrapped permanently in plastic. Exactly. (See alsoChapter 4: The Air that I Breathe.)

Cottages may flex, like they always have

Cottages were by definition not top-of-the-range housing. In the rockier areas of the country they might have been lucky enough to have had really firm walls of stone founded on good solid rock. But cottages were often built in rock-free areas out of less firm materials such as sticks and mud, and they were put straight on to the soil, or as near to it as made little difference. Mobile subsoils, such as clay, could affect the walls then, and still will now, so seasonal movement has always been likely. A cottage of timber construction is particularly prone to seasonal movement, as the timber itself responds to atmospheric and seasonal humidity, regardless of any soil movement.
