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

Highgate: the houses and the planning rules.
Highgate village sits on the hill above the Heath, a cluster of Georgian houses around the High Street and Pond Square, with large Victorian villas on the slopes towards the cemetery and Hampstead Lane, and 1930s and modernist houses on the estates around Highgate Wood. The conservation area is one of the oldest in London.
The houses are individual and so are the projects: restoring Georgian interiors, extending Victorian villas across steep gardens, and modernising mid-century houses while respecting their architecture. Two boroughs meet here, and we handle whichever one applies.
The Highgate Conservation Area covers the village and surrounding streets, and many of the older houses are listed.
Camden and Haringey
The borough boundary crosses the village; Camden covers the west side and Haringey the east, each with its own conservation area guidance and application process.
Listed houses
Much of the High Street, the Grove and Pond Square is listed, so internal work needs listed building consent.
Slopes and trees
Steep sites and protected trees affect extensions and basements; a topographical and tree survey is the starting point.

Loft Conversions in Highgate: your questions.
Is a loft conversion in Highgate permitted development?
Often, provided the added volume is within 40 cubic metres for a terrace or 50 for other houses and the dormer is at the rear. Flats, listed buildings and streets with Article 4 directions need an application to the London Borough of Camden and London Borough of Haringey.
How much headroom do I need for a loft conversion?
About 2.2 metres from the top of the ceiling joists to the ridge. Victorian and Edwardian roofs usually have it; 1930s hipped roofs often need a hip-to-gable conversion to make the space usable. We measure at the first visit.
