Hip-to-gable loft conversions in Greenwich

Covering Greenwich

Greenwich sits 5 miles east of London, with Blackheath 1 miles to the south-east and Catford 2 miles to the south.

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 does a hip-to-gable loft conversion involve?

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.

Do you need permission for a hip-to-gable loft conversion in Greenwich?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 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 Greenwich homeowners check first?

The new gable is usually rendered or built in matching brick.
Scaffolding goes up on the side of the house, which may need a neighbour’s agreement.
