Detailed Planning successfully obtained planning permission for a single‑storey rear extension and replacement of ground‑floor sash windows to a period property on Brackley Road in the London Borough of Hounslow. The existing house lacked a modern kitchen and dining space, and the ageing sash windows were in poor condition.
Our proposal adds a contemporary rear extension with a pitched roof and rooflights that complement the original architecture while accommodating a spacious kitchen–diner. Large bi‑fold doors open onto the garden, providing a seamless indoor–outdoor connection and allowing abundant natural light to flood the new space. We also specified new timber sash windows to the front elevation to enhance thermal performance and preserve the character of the house.
The planning drawings included detailed floor plans, elevations, sections and a 3D visual to illustrate the quality of the design. We demonstrated compliance with Hounslow Council’s design policies and conservation guidance, showing that the extension remains subordinate to the main house and respects neighbouring amenity. With permission granted, our clients can now proceed to transform their home. If you’re looking to extend or renovate a property in Hounslow, contact Detailed Planning for tailored advice.
