We recently completed this insulated garden office in our home town of Harpenden. With a hipped roof clad in cedar shingles and a verandah for the client to hang his hammock, the garden office provides a good sized work space away from the clients two young children.

Although the garden building required planning permission because it is higher than the 2.5m limit, this was readily granted. With 120mm of insulation in the roof and our standard 100mm thick walls and floor, the garden office has been very warm even during the recent cold. External cladding is vertical cedar and the decking is larch. The photo is not great, but we shall be taking more if and when the we see the sun again.
