The green credentials of Derwen cottage: The cottage has been refurbished with recycled, mended and donated materials. Non-toxic paint coats the inside walls, chemical free lime wash offers the midnight glow to the outside, leaving the ancient stone walls able to breathe. The wooden floors have non-toxic oil based seals. It has one heat source, the wood fueled ray-burn making the cottage cozy warm, with logs from a local supplier. We will recycle all your rubbish, we compost your kitchen waste to feed our organic polytunnel and the garden is free from all pesticides and chemicals. The bio sewage system is an ecologically designed filtering unit, and all water is metered so we know how much we use.
