Hello. This week David Elliot shares more about the design and materials for the new environmentally friendly building that Ben Law is helping the National Trust to build at Swan Barn Farm.
We have decided to call the new building Speckled Wood, after this butterfly that likes to frequent woodland rides and glades. They seem to be doing rather well here at Swan Barn Farm, thanks in some way at least to the work we have been doing here for the past few years.
The building will be based on a roundwood cruck timber frame. This construction technique produces attractive, functional buildings that can be sourced from the local woods. Exterior walls will be made of straw bales which will then either be rendered with lime or protected with oak boards. Interior walls will be wattle and daub with earth plaster. The roof will be made of chestnut shingles. We are very proud that pretty much all of the materials used in the building will be sourced in a sustainable way from woods within a couple of miles of the project site.
Above is a sketch of what the new building will look like, we have had a long haul to get the project off the ground and are still working hard on funding. Meanwhile we are also working hard in the woods getting the materials we will need for the project ready.
Here we are working in Ridden Corner Copse on Black Down felling and preparing the Sweet Chestnut which will be used for the timber frame of the building. The process becomes really fascinating when you start to think about which parts of the building the tree’s you are working with are going to be used for.
Above you can see me working on an oak in Witley Copse at Swan Barn Farm. The tree I am working on in this photo is destined for interior floorboards for the building. It will be sawn into planks and then air dried for a number of months before a final short spell of kiln drying.
Most of the timber for the building is coming from coppice woodlands. Coppicing is a traditional (and sustainable) form of woodland management which dates back many hundreds, if not thousands, of years. In a coppiced wood an area of the wood is felled each winter, but the trees don’t die, instead they re-grow from the cut stumps, the re-growth from the stumps can be harvested many times without any affect on the tree’s ability to grow again. Coppicing provides wood which is useful for a variety of purposes, but perhaps even more importantly it also provides the alternating cycles of light and shade, as well bare ground and dense shrubby thickets which are so vital to much of our precious woodland wildlife. Wild flowers grab the opportunity to grow and set seed in the light when the coppice is cut and woodland birds love to nest in the thickets as the woodland regenerates. There is nothing quite like a walk through a well managed hazel coppice in the spring, it is a vibrant place, bursting with life.

I am writing it as way of keeping a diary of progress on the project, telling its story I suppose, as well as letting people locally know about some of the other things that are going on at Black Down.
The project has been really interesting so far, and we are only just getting going, we have been lucky to have lots of local support and interest and we hope this will continue.
We have a busy year ahead of us, so wish us luck! If you are here in Haslemere this summer why not call in and see the building going up, there is easy access to Swan Barn Farm from the High Street, and the main footpath goes right past the project.
