Townshend Terrace Richmond Upon Thames TW9 1XL

This application seeks planning permission for the construction of a single-storey side infill extension, including the demolition of existing outbuildings and the alteration of the existing rear extension. The proposed side infill extension has been carefully designed to respect the site constraints, with the roof height limited to 2.2m along the side boundary. The roof adopts a mono-pitch form, rising to a flat roof with a maximum height of 2.94m, including parapet walls. The extension is intended to integrate seamlessly with the existing rear addition. As part of the proposals, the existing single-storey rear extension will be demolished and reconstructed on the same footprint, with an increased height of 2.94m to align with the new extension and create a consistent roofline. The application also includes a first-floor side extension measuring approximately 2.6m in depth and 1.4m in width, providing additional internal space to accommodate a second bathroom. This extension is set back from the original rear wall of the dwelling and features a roof set below the main roof ridge, ensuring that it remains subordinate to the host property. The design reflects and continues the existing built form along the side of the house while maintaining the overall hierarchy of the original dwelling. This application also includes the replacement of the existing concrete roof tiles with fibre cement roof tiles.
