Trouville Road Lambeth SW4 8QL
This proposal relates to the second-floor flat at 28 Trouville Road, a converted mid-terrace residential property. The building already features a rear-facing dormer at the main roof level. The applicant proposes to construct a new rear mansard dormer extension, designed to connect with the existing main dormer, but set significantly below it to ensure visual subordination and design harmony. The new dormer will have a mansard roof form with a 70-degree pitch, in accordance with Lambeth’s design guidance, and will be finished in matching tiles to retain visual continuity with the host roof. Two side windows will be incorporated into the dormer, and these can be obscured up to 1.7 metres to preserve neighbouring amenity and privacy. The extension will create approximately 10.13 square metres of internal floorspace, to be used as a home study by the occupant. The works will not alter the footprint of the building and will respect the external fabric and character of the host property.
