Clues to the Past: Uncovering conservation secrets at the Burgie Glasshouse

In June, eighteen intrepid volunteers traveled to Scotland to help conserve a 1912 timber glasshouse on the ancient Burgie Estate. The task was not easy, but it seemed straightforward: Repair and clean the timber framing, paint and prime it, then replace the missing glass panes to restore its former beauty and function. In spite of the occasionally “dreich” Scottish weather, our “AstraGals” as they christened themselves, restored beauty to the old timber structure, and got the frame and the historic cast iron sanded, painted, and water-tight.

But when eighteen people spend two weeks up-close and personal with a building, you’re bound to find some unexpected surprises…

All of the things we found challenged our ideas and preconceptions about what a historic greenhouse was “supposed” to look like. At first we didn’t look past the surface: everything was painted a crumbling, flaming white, which dovetailed easily with our own aesthetic that it was probably a crisp, glowing structure all of gleaming white paint and glass. But as soon as the first paint layers came off, it became clear this was not the whole story….

It began on Day One with the cast iron gutters, which were covered in peeling white paint and needed to be sanded down before being repaired and repainted. Within a few minutes, the power-sanders had penetrated the white paint and all the rust to reveal… a layer of deep green! This was particularly exciting because the other intact cast iron elements in the interior.. are also painted green. So now we have the idea that the green ventilator levers and brackets aren’t just an accent colour – we’re getting evidence of an actual paint scheme working within the greenhouse.

We were in two minds about the green thing. The trouble was, the green was the absolute bottom coat of all the layers. Generally, ironwork is and was painted with a priming coat of red lead paint, prior to the exterior layers being added. But here, we had to grapple with the question of whether perhaps for whatever reason, they used green paint to prime it, meaning that the visible layers would still have been white. OR, that perhaps the original installers cut some corners and didn’t prime it at all but painted the decorative green straight on.

The poor gutters – they do look white though, don’t they?

The glasshouse also has a decorative cast-iron finial on the roof ridge of the central house (there were formerly two matching finials, but one was stolen long ago…), and when we prised it off its base and started sanding down its white paint and rust, guess what we found… More green! Curiouser and curiouser…

IMG_8538

How many layers can you spot…?

Our volunteers spent two solid weeks face to face with the timber structure, sanding, chiseling, and repairing every spot they could reach, so it’s no surprise they picked up on things a casual observer might have passed right by. The glasshouse has stood for over a hundred years, and it’s definitely been repainted at least once in its lifetime. But, in some harder-to-reach corners, we were able to spot patches of what must have been the original paint – a very pale green! Now before we get carried away on the idea that the entire greenhouse was actually, well, green, I’m fairly certain that this was the original white lead paint that has aged to grey that just happens to have a greenish hue. Lead paints do tend to go greyer and paler as they age, as lead paint ages differently from modern oil or latex-based paints which crack. Lead-based paints powder away into a fine dust. So, for example, a door that was originally red would after a hundred years be much closer to pink.

Another exciting find was a decorative motif that still survived on some of the doors. Based on the flecks of paint still left, this curved ornament around the handles was originally a deep maroon, and even where the paint doesn’t survive well the outline of the motif is still clearly visible on most of the doors, indicating that it was pretty much ubiquitous throughout the glasshouse. It seemed a curious but distinctive feature, and when we mentioned it to Hamish, the owner, he told us that the Burgie Estate colour was, in fact, maroon.

IMG_8550

These maroon motifs were on almost every door in the greenhouse!

So there we had it, that little motif, that could so easily have been overlooked and carelessly sanded away, was a little piece of the original pride of Alexander Thompson’s new house and gardens. Just a little touch added, to say “Here I am – this beautiful building is mine.”

While the jury is still out on the original colour of the gutters and finial, the next conservation session definitely has plans to restore the maroon motifs to the doors. Paint samples were taken from various parts of the greenhouse to see if examination under a microscope revealed anything that our eyes couldn’t see, and I’m still slowly researching whether the green paint is more likely an exterior coat, or just a priming coat.

Another curious feature which I must have looked at a hundred times but never thought about, was the presence of little pulley wheels attached to certain parts of the greenhouse. Our brilliant volunteers theorised they could have belonged to adjustable blinds, which were sometimes used at greenhouses to provide shade in too-sunny conditions (in Scotland, seriously…?). This sounded plausible enough to me, though I didn’t know much about it, until a week later it turned out the AstraGals were right on the money!

Close up!

They don’t look like much, and it looks like someone tried to burn them, but I’m almost positive these are our blinds!

You see, down in the old boiler room are some rather strange-looking objects, that look like they’ve been thrown down there as a pile of old rubbish. I’d seen them a dozen times, but never wondered much about them, but once the seed about “greenhouse blinds” had been planted in my head… It suddenly clicked. Not only did we have the pulleys as evidence for the blinds, we actually had the blinds themselves sitting down in the boiler room all this while! This is incredible not just because we now know for certain that there were blinds, but now we even know precisely what they looked like and what they were made of. Until we can go down and rescue them and see what state they’re in, we won’t know whether they’re salvageable to actually re-install them. But maybe someday, when we find the expertise and/or a bit of funding, we can recreate the blinds to their original historic appearance. Gotta keep dreaming…!

Travel to Scotland for a Conservation Adventure!

Adventures In Preservation, a leading heritage conservation non-profit, is pleased to announce its upcoming session – restoring a historic greenhouse in the north of Scotland!Burgie Poster 2 Corrected

Restore the Greenhouse, Restore the Future!

Restoring heritage is always about more than just the buildings. While we might get caught up in questions of authenticity, of style and architectural purity and period-accurate method, at the end of the day, I think anyone who preserves heritage does so with the conviction that doing so ultimately makes the world a better place. Even if it’s just in a little tiny way – one building, a doorway, a chimneypiece, a stair-rail – there’s a satisfaction in knowing that you’ve concretely improved one tiny corner in a measurable way. Sometimes its difficult to see just HOW improving heritage improves the world… But then again sometimes it’s really very simple.

At Burgie, Mr. Hamish Lochore is using his historic building to save Scotland’s trees. He’s spent the past 12 years creating an enormous arboretum on his estate, where he grows both endangered Scottish species, as well as exotic species that a huge international network send him from all over the world (legally, of course!). He’s realised that all eight of Scotland’s native surviving species have already been negatively affected by climate change, and are increasingly vulnerable. He’s realised, as many at the Forestry Commission refuse to acknowledge, that the future of Scottish forestry might just require investigating alternative species. Despite the milder microclimate of the Moray coast, tiny seedlings of exotic varieties need a little help in their earliest years before they’re ready to brave the Scottish weather. And this is where the “so what” of the historic greenhouse comes into it.

Hamish has done an amazing thing with his ancestral estate. In the grand tradition of country estate owners everywhere, he has moulded and crafted his land into something better than itself. He has made it productive as well as decorative, educational as well as functional – and the same is true for his greenhouse.

IMG_3146

Don’t let the dull fibreglass roof deceive you, this glasshouse is a beautiful diamond in the rough!

The glasshouse was originally built in 1912, and it belongs to a world that no longer exists. The social structures of Edwardian Britain eroded after the First World War, and the rural economy and lifestyle changed forever. The glasshouse was built for a household that was designed not just to function, but to impress, with a staff of household servants as well as landscapers and gardeners to keep things running inside and out. The Burgie glasshouse speaks eloquently to this division between those who serve and those who are served; it has separate entrances for staff and visitors, as well as extensive sheds “behind the scenes” that are plainer and clearly meant for the dirtier staging-work of the paid gardeners. And one can just picture the wee coal-monkeys who were sent down into the lowered boiler-room to keep the water-pipes heated. Meanwhile, family members or meticulously-dressed visitors could come in from the walled garden to a gleaming fantasy of crisp, white timber, translucent glass, and of course a well-maintained riot of exotic plants and flowers.While this might not be every person’s ideal, with great divisions in wealth and privilege, it cannot be denied that such divisions wrought beautiful objects, buildings included. But the world has moved on, and the societal structure and purpose that appreciated greenhouses as status symbols and works of art no longer exists. And, like most buildings nowadays, century-old greenhouses are finding that they too must earn their keep to survive.

Temperate house interior

Historic glasshouses can be positively stunning. Although it’s hard to picture Burgie looking this grand, it once really did, and it could again!

How fortunate then that Hamish’s interests find more than enough uses for his broken-down old greenhouse! Hamish values his land and his heritage. As he said himself, “Who are we if we don’t leave things better than we found them?” But at the end of the day, he needs a working greenhouse for his eco-conservation work; whether it’s historic is in some respects neither here nor there. If he’s got one already on-hand, all the better! But in the state that it’s in… the Burgie greenhouse can’t exactly be said to be “working.” Most of the glass in the roof has fallen out over the centuries, and just to keep the water out Hamish put up some fibreglass sheeting. It keeps the inside relatively dry, but the essential function of a greenhouse – the capture and storage of heat and light through glass – is utterly lost. Right now it’s essentially just a glorified shed, and Hamish’s plants are suffering for it: shaded species are fine, but every year he loses dozens of carefully cultivated plants because they simply can’t get enough light and heat.

One of Hamish’s dedicated volunteers also has a love of historic buildings, and she saw the need – and the solution – right away. She reached out for help and enlisted the support of Adventures in Preservation, an American organisation that pair travel and tourism with heritage volunteering and conservation work. In June they brought 18 volunteers from the US and Australia (almost all women, as it happens!), and Hamish ripped the dirty sheeting off, freeing the beautiful wooden skeleton from its fibreglass prison! Over two weeks, the team sanded, chiseled and cleaned the entire wooden frame of the central house, then primed and painted it until it just glowed – literally, so white!

Fifteen beautiful “AstraGals” got the timber frame trim and glowing during AiP’s June session!

More about the amazing things we discovered during our work – and a few unsolved mysteries we uncovered – in a subsequent post.

But for now, Hamish’s beautiful greenhouse is roofless and gaping open to the elements, and Adventures in Preservation and I are working hard to get a group back in the autumn to get a roof on it before the winter weather sets in – a scenario that would be bad for the greenhouse, and bad for Hamish’s trees!

Registration for the September-October session is live, and will involve cutting and laying the glass for the roof!

‘This blessed plot, this earth:’ The UNESCO World Heritage Register

Survived Week 2! Turns out life isn’t so bad when you’ve not got a cold – this whole crazy commuting thing might turn out alright after all!

After our Week 1 crash course on history and theory, we have finally gotten to the fun bits: actually getting our hands dirty with the real work of conservation. My first attempt to survey the dimensions of a room using a ruler, a compass, and a technique called “triangulation” was pretty comical, but we’ll leave aside tales of me on my hands and knees crawling under antique furniture and poking my nose into really really dirty corners of staircases to examine their construction for another post, when I have a better sense of what I’m actually doing.

This week was also our first taster of elective courses, and mine – World Heritage – is totally awesome. By now pretty much everyone has heard of the UNESCO World Heritage sites – if you’ve ever seen the Statue of Liberty, the Great Wall of China, Notre Dame de Paris, Westminster Abbey, visited Yosemite or Yellowstone or the Grand Canyon, or set foot in the city of Edinburgh, congratulations! You’ve experienced a monument of “outstanding universal value” to the entire race of mankind. Really the list is quite extensive – now over a thousand entries – and growing every year. Here’s a version from the World Heritage Centre’s own website, grouped by country: http://whc.unesco.org/en/list/

But the rationale behind the list might be surprising. Okay, the sights I listed above – you might think the Statue of Liberty, how *yawn* very American (even though it’s French) – seem like an obvious “who’s who” of tourist destinations, almost to the point of being trite. But really the list (which you should totally spend a couple hours poking about and getting lost in), is a lot more complex in its composition. Even though lots of people turn it into a kind of to-do list, the “attraction” of the site, or the ability to take a selfie in front of it, takes a backburner to the significance of the site, which might not be that instagrammable, or even suitable to visitors. If the list were all just castles, cathedrals, and national parks, it would hardly be a comprehensive representation of globally valuable heritage. No, the scope is so much broader, and encompasses, for instance, sites that illustrate progress in human development. Yes, the Golden Gate Bridge is very impressive, but think of the power of a site that tells a story not just about one nation at one time in history, but actually links in with our evolution as a species. For example this site near Mount Carmel in Israel, contains an unbroken record of human habitation, stretching back over 500,000 years, leaving archaeological remains that actually trace our development from pre-human species, to hunter-gatherers, to settled cultivators of the land. But pictures won’t tell you that, and millions of tourist feet tramping over the site would only damage it. (This is one of the unfortunate consequences of the list. Inclusion on the list does not come with funding for maintenance, but it does usually come with hordes of tourists who use UNESCO as a sort of hit list)

Apart from including sites important to humanity, UNESCO also tries to include a diversity of types of sites, that can be representative or typical of some particular aspect of nature or culture. This includes sites of colonization or settlement, such as L’Anse aux Meadows, the site of pre-Colombian Viking settlement in Canada, as well as testaments to human technological and industrial achievements, such as the Wieliczka Salt Mines outside Kraków, Poland.

Natural sites are fair game as well, and are selected for inscription based on their extreme aesthetic beauty or remarkability, for their perfect illustration of geologic phenomena, or by representing phases of the earth’s formation. The Grand Canyon seems a no-brainer judging by its listing description as “the most spectacular gorge in the world.” The Galápagos Islands were the very first site to be listed, based on their clear evidence of the volcanic processes that formed them, and on their status as a “living museum” of evolution.

More recently, the focus has shifted to sites that span both the human and the natural worlds, under a category called “cultural landscapes,” that illustrate ways in which spectacular natural formations have interacted with outstanding human settlement or achievement. This encompasses sites such as Thingvellir National Park in Iceland, where the medieval Norse settlers used the dramatic rift between the North American and European tectonic plates as a titanic ceremonial stage for their sophisticated and participatory system of law.

The spectacular and dramatic formations of South Africa’s Drakensberg Mountains are littered with prehistoric human settlements and contain the largest concentration of cave paintings south of the Sahara. And the Tokay Wine Region in Hungary is remarkable for its centuries-old tradition of a very specific, highly regulated viticulture, making use of the landscape and traditional methods to make [really really delicious] wine. In an otherwise unremarkable region of Sweden, one large hillside is littered with the remains of an ancient people, who carved tens of thousands of images into the rocks of the landscape, over a period of several thousand years. The Tanum Rock Carvings depict an amazing variety of very human images, such as two lovers embracing, or a woman mourning a man, and they interact with other archaeological features in these hills, such as enormous chambered cairn tombs.

Here are the 12 sites that comprised the very first list published in 1973, and from which the present list has grown: http://edition.cnn.com/2014/06/13/travel/unesco-first-12-world-heritage-sites/

Check it out, and prepare to be surprised – given what we think of as the world’s great tourist sites, the ones that made the list of the dozen most important sites in the world as of 1973 are probably not what you’re expecting… 🙂
