Architects in Wimbledon for Extensions, Loft Conversions & Planning
From planning applications to structural design — we help Wimbledon homeowners extend, convert and improve their homes.
Why Wimbledon Projects Need Careful Planning
Wimbledon falls within the London Borough of Merton, which contains over 25 conservation areas — several concentrated around Wimbledon Village, Wimbledon Hill Road and the Ridgway. Large detached properties in the Village sit alongside Victorian and Edwardian terraces in the town centre, each with different planning considerations and design opportunities.
Merton Council applies its Sites and Policies DPD alongside the Core Strategy when assessing extensions, loft conversions and new-build proposals. Properties near Wimbledon Common face additional constraints under Metropolitan Open Land (MOL) protections, and those in conservation areas are subject to Article 4 directions that remove permitted development rights for front elevations, boundary treatments and roof alterations.
We prepare applications that address Merton Council’s policies on residential design, covering everything from single-storey rear extensions and side returns to substantial basement excavations. Our architects handle full planning submissions, lawful development certificates and appeals — working directly with Merton’s planning officers throughout the process.

Areas We Cover in Wimbledon
One of London's most desirable residential areas, centred around the High Street and the edge of Wimbledon Common. The conservation area contains large detached and semi-detached period properties with generous gardens. Planning applications here require sensitive design that preserves the village character while accommodating modern living.
A vibrant area around the station with a mix of Victorian terraces, Edwardian semis and some post-war housing. Properties here offer excellent potential for rear extensions, side returns and loft conversions. The town centre's excellent transport links make well-designed extensions a strong investment.
More affordable than the Village, South Wimbledon features Victorian terraces and inter-war housing well suited to rear extensions and loft conversions. Most properties retain permitted development rights, allowing many projects to proceed without a full planning application from Merton Council.
Residential streets surrounding Wimbledon Park feature Edwardian and inter-war semis, many with good-sized rear gardens ideal for single and double-storey extensions. Properties overlooking the park may face additional design considerations to protect visual amenity from public spaces.
A popular family area with 1930s semis and some larger detached properties along the main roads. Raynes Park is well suited to hip-to-gable loft conversions, rear extensions and garage conversions. Most properties outside conservation areas benefit from permitted development rights.
The Merton Park conservation area features distinctive Arts and Crafts housing from the early 1900s. Extensions here require careful design that reflects the original architectural character, including materials, window proportions and roof forms. We have experience working within these specific design constraints.
A regenerating area with a mix of Victorian terraces and post-war housing. Properties offer strong potential for rear extensions, loft conversions and full refurbishments. Good transport links via the Northern Line make Colliers Wood increasingly popular for families extending their existing homes.
Frequently Asked Questions
Many single-storey rear extensions in Wimbledon fall under permitted development, but homes in conservation areas like Wimbledon Village, Wimbledon Hill Road or Merton Park may have Article 4 directions removing these rights. We check all constraints with Merton Council before advising on the best route for your project.
A single-storey rear extension in Wimbledon typically costs between £55,000 and £95,000 for construction, depending on specification and size. Our architectural fees are fixed and transparent — we provide a full quote after an initial consultation so there are no surprises.
We handle the full design and approval process — from initial feasibility and measured survey through to planning drawings, structural calculations and Building Regulations submissions. For Wimbledon properties, we assess roof type, head height and party wall considerations to recommend the best conversion approach.
Basement extensions are increasingly popular in Wimbledon, particularly in the Village where plot sizes allow it. Merton Council requires a detailed construction management plan, structural assessment and consideration of groundwater conditions. We manage the full design and planning process for basement projects.
From initial consultation to completion on site, a typical double-storey extension in Wimbledon takes 10 to 14 months. The design and planning phase usually takes 3 to 4 months, with construction following over 5 to 8 months depending on complexity and builder availability.
A local architect understands Merton Council's planning policies, conservation area sensitivities and the character of Wimbledon's distinct neighbourhoods from the Village to South Wimbledon. We have direct experience with Merton's planning team and know what they look for in applications, giving your project the best chance of approval.
