This project next to the woods just south of Oxford is nearing completion. The wood cladding is looking very fresh but the untreated white cedar shingle on the lower half will fade to a pale white colour and the larch boards above will gradually silver with time.
A corrugated tin roof is a very cheap, robust and readily available material and being very close to trees will be hardwearing against the possibility of falling branches.
The approach here has been to achieve high quality for low cost. It has meant carefully thinking about where to spend money and keeping the detailing simple. Above all retaining as much of the existing building as possible is a sure way of not only keeping the costs down but also reducing the environmental impact.
