SW19 · London Borough of Merton
Builders in Wimbledon
Wimbledon has one of the widest mixes of housing in South West London, from large Victorian villas on the hill to tight Edwardian terraces around the Broadway and 1930s houses further out. That variety means the right extension or loft conversion, and the planning route to it, depends very much on which street you live on.
Homes in Wimbledon
Merton's Borough Character Study describes Wimbledon growing outward from the town centre in the second half of the 19th century, with villas and terraces fanning out along new roads, before building peaked in the 1930s. Many of the largest Victorian houses were later divided into flats or replaced.
For homeowners, that history shapes the options. Terraced streets suit side-return and rear extensions and rear dormer lofts, and the Character Study itself identifies sensitive extension and conversion of terraced streets as an opportunity. Larger detached and semi-detached houses on the hill often have the space for wraparound or double-storey extensions, while houses that have been split into flats lose permitted development rights and need planning permission for most extensions.
Planning in Wimbledon
Wimbledon is covered by the London Borough of Merton. The town has several conservation areas, including Wimbledon North, Wimbledon Village, Wimbledon Hill Road, Wimbledon West, Wimbledon Broadway and Wimbledon Chase, and each has a published character assessment or design guide on Merton's conservation areas list. In a conservation area, permitted development rights are more limited, so changes such as side extensions and cladding need planning permission, and it is worth reading the guidance for your area before designing a scheme.
Merton lists no householder Article 4 directions for Wimbledon on its Article 4 page at the time of writing, but always check the current position for your address. Parts of north Wimbledon near Wimbledon Park fall within the London Borough of Wandsworth instead, so confirm which council covers your street before applying.
Basements across Merton are governed by Policy D12.11 of the Merton Local Plan (adopted November 2024). It limits a basement under an existing home to a single storey, restricts how far it can extend beyond the original house, and requires a Basement Impact Assessment, a drainage strategy, a construction method statement and a construction traffic management plan with the application. In conservation areas, basements and their lightwells must conserve or enhance the area's character.
Worth knowing locally
- Wimbledon Hill Road climbs roughly 20 metres between the Worple Road junction and the top of the hill, so gardens and foundations on the slope vary a lot from one house to the next.
- Merton's guidance for Wimbledon Chase singles out boundary treatments, windows, roofs and porches, so matching the original details matters there.
- Merton offers a pre-application advice service for householders, which can be worth using for schemes in conservation areas.
