Development description

Construct a single storey rear and side ground floor extension together with the provision of a rear dormer to the existing attic space, in conjunction with the installation of new velux roof lights to the front and rear of the existing roof. The works will include a 25sqm garden room, incorporating a gym and bathroom. Extensive internal alterations and modifications will be carried out to the existing dwelling, including the lowering of the cills to the ground floor windows of the front elevation. A veranda will be added to the front elevation with a covered outdoor seating area to the rear.
