Planning permission drawings, loft conversions, and extensions for Raynes Park's 1930s semis and family homes. MCIAT chartered, fixed fees, Merton planning expertise built in.
Raynes Park sits in the SW20 postcode within the London Borough of Merton. The neighbourhood's tree-lined streets of 1930s semi-detached houses and Edwardian properties make it a popular family area with consistent demand for extensions and loft conversions.
1930s semis: Raynes Park's inter-war semis are ideal for hip-to-gable loft conversions, side extensions, and rear extensions. The typical hipped roof can be squared off and a rear dormer added to create a generous loft room. Under permitted development, these works can proceed without planning permission.
Edwardian properties: The area's Edwardian houses offer good roof voids for loft conversions and adequate garden depths for rear extensions. We design schemes that respect the period character while maximising usable space.
Merton design guidance: Merton Council has published an SPD on residential extensions with specific guidance on dormer design, extension depths, and materials. We design schemes that comply with this guidance from the outset.
Permitted development: Most Raynes Park properties enjoy full PD rights. We confirm eligibility, prepare building regulations drawings, and manage any prior notification required for larger extensions.

Start a free quoteYes, hip-to-gable loft conversions are very popular on Raynes Park's 1930s semis. Under permitted development, these typically proceed without planning permission. We survey your roof and prepare building regulations drawings.
Under permitted development, semi-detached houses can build single-storey rear extensions up to 6 metres. Two-storey rear extensions up to 3 metres are also possible under PD. We confirm the maximum for your property.
Merton's SPD requires dormers to be set back from the eaves, set in from party walls, and subordinate to the existing roof. Materials must match the existing roof covering. We design compliant dormers.
Our Essentials package starts from £840. The Complete package from £1,750 covers planning and building regulations plus structural calculations. Fixed fees throughout.
