Loft Conversions in Wimbledon.
A loft conversion adds a bedroom and bathroom without touching the garden, and in most of Wimbledon it is the most cost-effective way to gain a floor. Which type suits your house depends on the roof: Victorian and Edwardian terraces usually take a rear dormer, 1930s semis with hipped roofs need a hip-to-gable conversion to make the space usable, and in conservation areas a mansard or rooflight scheme may be the only option.
We start by measuring the roof. About 2.2 metres from the top of the joists to the ridge is needed for a comfortable room; we check this at the first visit before anything is drawn. From there our architects design the layout and the stair, our engineers design the new floor and any steelwork, and our team builds it with the house occupied throughout.
Most lofts are permitted development within the 40 or 50 cubic metre allowance, with the dormer at the rear. Flats, listed buildings and streets with Article 4 directions need a planning application, and every loft needs building regulations approval for the structure, fire escape and insulation. We manage all of it.

Wimbledon: the houses and the planning rules.
Wimbledon divides into the village on the hill beside the Common, with its Georgian and Victorian houses and some of the largest private homes in south London, and the town below it, with Edwardian terraces and semis running down to the station. Between them are the Parkside roads of detached houses that attract owners with substantial budgets.
Projects here range from complete refurbishments of village houses, with basements and garden rooms, to extensions and lofts on the Edwardian streets. Merton's conservation guidance applies in the village and around the Common; elsewhere permitted development covers much of what owners want to do.
The Wimbledon Village, Wimbledon North and Merton Park conservation areas cover the village, the common edge and the garden suburb; most other streets are unrestricted.
London Borough of Merton
Merton decides applications. Within the Wimbledon Village and North conservation areas, roof changes and rear extensions need a full application; outside them permitted development often applies.
Large houses
Basements, pool houses and garden buildings on the larger plots need a householder application and, near the Common, careful attention to trees.
Merton Park
The garden suburb has Article 4 directions and specific guidance on hedges, windows and extensions.
