Hip-to-Gable Conversion in Lewisham

A hip-to-gable conversion in Lewisham starts from £30,000 and typically takes 8–12 weeks. We handle the whole job, from the first survey to the final sign-off. In short, you get a finished room and one clear price.

A hip-to-gable conversion replaces the sloping hip end of your roof with a tall, vertical gable wall. This one change opens up a large chunk of floor area that the slope used to waste. It works best on semi-detached and detached homes that have a hipped roof. For the biggest gain, we often pair it with a rear dormer, which together create a generous, light-filled room.

London's Victorian and Edwardian terraces suit this type of conversion particularly well. Our local team knows the planning rules and the roof structures common to Lewisham. As a result, we can advise on the right approach for your home during the free survey, before you commit to anything.

Every hip-to-gable conversion we build in Lewisham includes the full package. That means structural design, planning checks, building regulations submission, and project management from start to finish. Better still, you receive a single fixed-price quote, with no hidden costs and no surprises along the way.

Hip-to-Gable Conversion Lewisham: FAQs

How much does a hip-to-gable conversion cost in Lewisham, London?

A hip-to-gable conversion in Lewisham typically starts from £30,000. The final figure depends on three things: the size of your loft, how complex the build is, and any planning requirements specific to your property. First we visit for a free survey, then we send a fully itemised, fixed-price quote in writing within 48 hours. That way you see exactly what you pay for, with no guesswork.

Do I need planning permission for a hip-to-gable conversion in Lewisham?

Most hip-to-gable conversions in Lewisham fall under Permitted Development rights, so you usually do not need full planning permission. However, homes in conservation areas or under an Article 4 direction can need formal consent. We run every planning check as part of your free survey, at no extra charge. As a result, you know where you stand before any work begins.

How long does a hip-to-gable conversion take in Lewisham?

A hip-to-gable conversion in Lewisham typically takes 8–12 weeks from start to finish. That window covers the structural work, any planning or building control submissions, and the full build. We give you a precise timeline with every fixed-price quote, so you can plan around it. In practice, we keep you updated at each stage too.

Is my Lewisham home suitable for a hip-to-gable conversion?

London's Victorian and Edwardian terraces are often well-suited to loft conversions. Whether your own home suits a hip-to-gable conversion comes down to your roof structure, ceiling height, and available headroom. Our specialists check all three during the free survey. They then confirm the best option for your budget and your goals, with no obligation to go ahead.
