Why Merton Homeowners Choose Crown Architecture
The London Borough of Merton offers some of south London’s most varied and appealing residential environments. Wimbledon Village (SW19) is one of London’s most prestigious addresses — a hilltop community of Georgian and Victorian houses, independent shops, and Michelin-starred restaurants that manages to feel simultaneously rural and metropolitan. Wimbledon town centre, immediately below the Village, has a strong residential offer across all price points. South Wimbledon and Colliers Wood (SW19) are undergoing gradual regeneration. Morden (SM4) offers excellent value, direct access to the Northern line, and a variety of inter-war and post-war housing. Mitcham (CR4) has a long history and an increasingly valued housing stock of Victorian and Edwardian terraces.
At Crown Architecture, we work across this full range of Merton’s housing types and planning environments. Wimbledon Village requires the highest level of design sensitivity and conservation planning expertise; properties in Morden and Mitcham offer excellent extension opportunities within a more permissive planning context. Our team brings the same rigour and creative ambition to every commission.
Our Services in Merton
Extensions
Whether you own a substantial Edwardian detached house in Wimbledon Village or a 1930s semi in Morden, a well-designed extension can transform your home. We design rear, side, and double-storey extensions across all of Merton’s housing types, always responding to the specific character and planning context of each property.
Loft Conversions
Merton’s Victorian and Edwardian stock has excellent loft conversion potential. A dormer loft conversion to a typical Wimbledon or Raynes Park terrace can add one or two bedrooms and a bathroom. We manage the full process, including planning, building regulations, and construction oversight.
New Build Residential
Merton has development opportunities across the borough, from infill sites in Wimbledon town centre to suburban plots in Morden and Mitcham. Crown Architecture provides full new-build design services.
Refurbishment and Remodelling
Wimbledon Village’s exceptional housing stock benefits from careful refurbishment that respects and enhances its historic character. We combine architectural expertise with interior design capability to deliver whole-house transformations.

Conservation Areas in Merton
Wimbledon Village Conservation Area — Wimbledon Village (SW19) is one of south London’s finest conservation areas, centred on the Village High Street, the Church of St Mary the Virgin, and the surrounding Georgian and Victorian houses. The conservation area appraisal provides detailed design guidance for extensions, alterations, and new development. Wimbledon Village has strict guidance on materials, scale, massing, and the importance of protecting views across the common. Crown Architecture is experienced in designing within this demanding but rewarding planning context.
Wimbledon Town Centre Conservation Area — Covering the Victorian and Edwardian commercial and residential buildings of Wimbledon town centre, this conservation area includes the notable terraces on Wimbledon Hill Road and the surrounding residential streets. Materials, fenestration, and scale are carefully controlled.
Colliers Wood High Street Conservation Area — Centred on the historic high street of Colliers Wood (SW19), this conservation area encompasses Victorian and Edwardian commercial buildings and the surrounding residential streets. Crown Architecture has experience with residential projects in this setting.
Planning Timelines
Standard householder applications in LB Merton are typically determined within 8–10 weeks of validation. Conservation area applications (particularly in Wimbledon Village) may take longer, as Merton’s conservation officers are thorough and well-resourced. Pre-application advice is strongly recommended for Wimbledon Village projects.
Popular Projects in Merton
Rear Extension and Loft — Woodside Road, SW19
A Victorian semi-detached house in Wimbledon, close to Wimbledon Park. The owners wanted to create an open-plan kitchen-dining room and add a master suite at loft level. Crown Architecture designed a 4m rear extension and rear dormer loft conversion, both in London stock brick and slate to match the Victorian original. The scheme was outside the Wimbledon Village Conservation Area, so Permitted Development applied for both elements, confirmed by a Lawful Development Certificate from LB Merton.
Whole-House Refurbishment — Parkside, SW19
A substantial Victorian detached house on Parkside, Wimbledon — one of the grandest residential streets in the borough, adjacent to Wimbledon Common. The owners commissioned Crown Architecture to remodel the entire interior: opening up the ground floor, adding a new kitchen-dining extension, converting the loft, and upgrading all bathrooms and utility spaces. The property is not listed, but sits in the Wimbledon Village Conservation Area, requiring a conservation area consent application. Full consent was secured after a positive pre-application engagement with Merton’s conservation officer.

Frequently Asked Questions — Architect in Merton
Q: What are the conservation areas in LB Merton?
A: Key conservation areas include Wimbledon Village, Wimbledon Town Centre, and Colliers Wood High Street. Each has a detailed character appraisal and specific design guidance. Crown Architecture reviews conservation area requirements for every project.
Q: Do I need planning permission to extend in Wimbledon Village?
A: Yes. Wimbledon Village Conservation Area removes or restricts permitted development rights for extensions and alterations. All visible external works typically require full planning permission and must comply with the Council’s conservation area design guidance.
Q: How long does planning take in LB Merton?
A: Standard applications are typically determined within 8–10 weeks. Wimbledon Village conservation area applications may take longer, as Merton’s conservation officers apply detailed scrutiny. Pre-application advice is strongly recommended.
Q: Can I extend my 1930s semi in Morden without planning permission?
A: Outside conservation areas, many extensions in Morden (SM4) fall within Permitted Development rights, subject to standard size limits. Crown Architecture confirms the planning route at the feasibility stage.
Q: What is special about Wimbledon Village architecture?
A: Wimbledon Village features a mix of Georgian, Victorian, and Edwardian houses, many substantial in scale and set in generous plots. The hilltop setting, proximity to Wimbledon Common, and the village atmosphere create one of south London’s finest residential environments. Design standards for extensions and alterations are correspondingly high.
Q: How much does an architect cost in Merton?
A: Fees for a full residential service in Merton are typically 7–12% of construction cost. Crown Architecture provides transparent, fixed-fee quotations for all project types.
Q: Can I do a loft conversion in Wimbledon?
A: Yes. Wimbledon’s Victorian and Edwardian terraces have excellent loft conversion potential. In conservation areas, the design of the loft conversion (particularly any dormer) will be assessed carefully. Outside conservation areas, a rear dormer often falls within Permitted Development.
Q: Do I need a party wall agreement in Merton?
A: The Party Wall etc. Act 1996 applies to shared wall works and excavations near neighbouring foundations, as it does across London. Crown Architecture advises on party wall obligations.
Local Character — Merton
Merton’s great draw is Wimbledon — not just the All England Lawn Tennis Club (SW19) and its annual tournament, but the exceptional quality of life that the broader area offers. Wimbledon Village, at the top of the hill, has the feel of an affluent Surrey village dropped into south London: independent boutiques, outstanding restaurants and gastro-pubs, and a High Street that has retained its individual character against the odds. The proximity of Wimbledon Common — over 1,100 acres of woodland and open space — is one of the borough’s greatest assets.
Wimbledon town centre, below the Village, is a thriving suburban hub with a large Waitrose, the New Wimbledon Theatre, and a growing restaurant and bar scene. South Wimbledon and Colliers Wood (SW19) are benefiting from Northern line access and are undergoing gradual gentrification.
Raynes Park (SW20) is one of south London’s best-value residential areas — Victorian and Edwardian terraces with fast trains to Waterloo. Morden (SM4) is a Northern line terminus, offering excellent transport accessibility and a variety of inter-war housing in attractive condition. Mitcham (CR4) has a long history as a market gardening area and retains a distinctive character, with the old town centre around the Fair Green gradually reviving.
Transport links throughout the borough: Wimbledon (District line and South Western Railway to Waterloo in 20 minutes), South Wimbledon and Morden (Northern line), and Colliers Wood (Northern line).
