Architects in
Wimbledon

Wimbledon homes have something most of London does not - space. Bigger gardens, wider plots, detached houses with room on all sides. The projects here tend to be more ambitious because of it. Extensions that really stretch out, loft conversions with proper headroom, and sometimes knocking a house down and starting again entirely.

What We Do in Wimbledon

Extensions, loft conversions and new builds

Wimbledon is different from inner London. The houses are bigger. The gardens are deeper. You are not working with a narrow terrace and a two-metre rear return - you are working with a detached or semi-detached home that has genuine potential. That changes what is possible.

Rear and side extensions here can be substantial. Wrap-around extensions that open up the entire ground floor are common, and the plots are often large enough to go further - a new build on a subdivided garden, or a basement conversion beneath an existing house. Loft conversions work well too, especially on the larger roofs you find across SW19.

We handle architecture and construction under one contract. One team from the first sketch through to the finished build, no separate builder to find.

Local Knowledge

Understanding Merton and Wimbledon's planning context

Planning in Wimbledon is not one-size-fits-all. Wimbledon Village sits within a conservation area, which means tighter controls on what you can do to the exterior of a building. Outside the Village, much of Wimbledon falls under standard Merton Council planning policies, and permitted development rights apply to many smaller extensions without needing a formal application.

The larger plots across Wimbledon allow for more ambition. Where an inner London terrace might be limited to a three-metre rear extension, a detached house in Raynes Park or Southfields can often go further. Merton Park has its own distinctive character with the original John Innes estate houses, and the council treats those areas with care. We know the differences and design accordingly.

New builds are a realistic option here too. Larger gardens can sometimes be subdivided, and infill plots do come up. Merton's local plan supports new residential development where it respects the existing streetscape.

We are an architecture and construction studio. One team handles design, planning and building - all under one roof. No separate contractor to source, no gaps between what gets drawn and what gets built.

Common Questions

Architecture in Wimbledon - answered

Do I need planning permission for an extension in Wimbledon? +
Not always. Smaller rear and side extensions in Wimbledon often fall under permitted development, which means no formal planning application is needed. However, if your property is in the Wimbledon Village conservation area, permitted development rights may be restricted and you will likely need to apply. Merton Council also has specific policies on extensions in residential areas, so we check the planning position for every property before we start.
How much does a house extension cost in Wimbledon? +
Construction costs in Wimbledon typically range from £2,500 to £3,800 per square metre, depending on the specification. Because many homes in the area are detached or semi-detached with larger plots, extensions tend to be more generous than in inner London - and the overall project cost reflects that. We provide a detailed cost estimate early in the process so you can plan with confidence.
Can I build a new home in Wimbledon? +
Yes, and Wimbledon is one of the better parts of London for it. Larger gardens on detached properties sometimes allow plot subdivision, and there are infill development opportunities across the borough. Merton's local plan supports sensitive new residential development where it fits the character of the area. We have experience with new build projects and can advise on feasibility from the outset.
What areas near Wimbledon does Rosace also cover? +
We work across South West London and beyond. Alongside Wimbledon, we regularly take on projects in Putney, Wandsworth, Kingston, Richmond, Morden and Colliers Wood. We also work in other parts of London and selected locations outside the capital.
