Loft Conversions in Muswell Hill.
A loft conversion adds a bedroom and bathroom without touching the garden, and in most of Muswell Hill 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.

Muswell Hill: the houses and the planning rules.
Muswell Hill was built almost in one go between 1896 and 1914, which is why it is so coherent: wide avenues of red-brick Edwardian houses with tiled paths, stained glass and generous rooms, radiating from the Broadway. The houses are large, the gardens are long and the roofs have room to convert.
It is a family-house market, and the projects match: side-return and rear extensions for open-plan kitchens, loft conversions with rear dormers, and refurbishments that keep the Edwardian detail while renewing everything behind it.
The Muswell Hill Conservation Area covers the Edwardian centre and the avenues around it.
London Borough of Haringey
Haringey decides applications. Within the conservation area, front alterations and roof changes visible from the street need permission; rear extensions are often permitted development.
Lofts
Edwardian roofs generally offer good headroom; rear dormers are usually permitted development outside Article 4 streets.
Trees and gardens
Mature street and garden trees are often protected; we check for tree preservation orders before designing extensions.
