Extensions & alterationsCommercial premises

Proposal

Erection of a side extension to provide a cycle store for both residential and commercial use. Alterations to the access arrangement for the upper-floor flats, including the installation of a new external metal staircase and the creation of a new upper-level entrance doorway and External Soundproof & Obscured metal studs with timber wall Panel & Storm Force 25mm Clear Multiwall Polycarbonate Roof Sheet are proposed to provide privacy, outlook, and noise and disturbance and to prevent overlooking into neighbouring properties, particularly towards the opposite windows. The design maintains adequate daylight and ventilation while ensuring visual privacy for both occupants and neighbours. Data via plota.co.uk
