Proposal

Proposed construction of a full-length rear dormer roof extension to provide an additional bedroom and a bathroom at loft level. The dormer will be set back a minimum of 600mm from the neighbouring property boundary and a minimum of 500mm from the existing eaves, in order to minimise visual impact and protect neighbouring amenity. The ridge height will be retained, with a minimum distance of 300mm maintained between the existing ridge line and the new dormer roof, ensuring the dormer remains subordinate to the host roof and is not visible from the front elevation. In addition, 2 rooflights (Velux-style) windows are proposed on the front roof slope to provide natural daylight to the loft accommodation. The proposed development has been designed to respect the character and appearance of the existing dwelling and the surrounding area, while providing improved internal accommodation.
