Hip-to-gable loft conversions in Eltham

Covering Eltham

Eltham sits 9 miles south-east of London, with Blackheath 2 miles to the north-west and Welling 3 miles to the east.

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.

What hip-to-gable loft conversions typically cost. These are guide ranges; the written quote for your house replaces them.

Hip-to-gable loft conversions	Guide price incl. VAT
Hip-to-gable with rear dormer	£60,000 to £80,000
Double hip-to-gable (detached house)	£70,000 to £95,000

What approvals does a hip-to-gable loft conversion need in England?

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 I think about before starting?

Hip-to-gable volume counts towards the permitted development allowance.
Matching old clay tiles can be difficult; reclaimed tiles are often used.
