This recently completed project features an extension and new roof, as well as conservation and refurbishment works to an early eighteenth century grade II listed farmhouse. Our proposal entailed removing a thermally poor conservatory and replacing it with a garden room that can be used all the year round. The new extension is constructed in an oak frame and features a lead roof with a glazed lantern. In addition, on another building, we reinstated a gable including stone mullioned windows and added a pitched roof supported on oak purlins and covered in Cotswold stone tiles.
