Hip-to-gable loft conversions in Fulham

Covering Fulham

Fulham sits 4 miles south-west of London, with Chelsea 1 miles to the east and Putney 2 miles to the south-west.

Homes in London

Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.

What is a hip-to-gable loft conversion?

Hipped roofs are common on 1930s semis and have little usable volume until the hip is squared off. We rebuild the gable in brick or block, extend the roof structure, form the rear dormer and finish the new floor, keeping the front roof slope looking as close to the original as possible.

Planning and building rules in Fulham

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

In England many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m.

What should Fulham homeowners check first?

Hip-to-gable volume counts towards the permitted development allowance.
Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.
