Hip-to-gable conversions to South Hampstead’s semi-detached villas — squaring off a hipped roof for usable space, designed for the conservation area and Camden consent.

A hip-to-gable conversion extends a sloping (hipped) roof end up to a vertical gable, turning a cramped, angled loft into a full-height room. It suits the semi-detached and end-of-terrace Victorian villas that are so common in South Hampstead, many of which were built with hipped roofs at the ends.
Because it changes the roof profile, a hip-to-gable is sensitive in a conservation area: Camden will look at how prominent the new gable is and whether it sits comfortably with neighbouring roofs. It often works best where the change is to a side elevation, or where a neighbour has already gabled and the pair can be balanced.
We survey the existing roof, confirm whether a gable can be justified, and where it can we pair it with a rear dormer to make the most of the new volume — with structure, stair and party wall all in one contract, and honest budgets in pounds sterling.
A hip-to-gable changes the shape of the roof, so prominence and neighbours matter.
It only applies to houses with a sloping hipped end — the semi-detached and end-of-terrace villas.
Raising a hip to a gable alters the roofline, so Camden weighs how visible and how harmonious it is.
A gable plus a rear dormer turns an awkward loft into a genuine room; we design them together.
Building up the gable needs proper structural support and party wall care where it meets a neighbour.
