Loft Conversion in Greenwich

What your roof can take

The first question on any loft is head height and the roof structure. A traditional cut roof and a modern trussed roof convert differently, and the ridge height sets what is possible. We assess this at the start so the design is grounded in what your roof can actually deliver, not an optimistic sketch.

Dormer, hip to gable, or mansard

The right loft type depends on the roof and the planning context. A rear dormer adds the most usable space, a hip-to-gable unlocks a side slope, and a mansard suits many period and conservation streets. We match the type to your house and the local planning position, then design it to look considered, not bolted on.

Permitted development and protecting the works

Many lofts are possible under permitted development, within volume limits and provided the property is not on designated land. Where that applies we obtain a lawful development certificate to protect the works. We also coordinate the structural design and any party-wall awards with neighbours.

Planning in Greenwich

Approved is a local question.

A loft conversion in Greenwich is decided by the Royal Borough of Greenwich, against its own local plan. Loft conversions are often permitted development within the additional roof-space volume limits, but those rights are removed in conservation areas and on other designated land, so the designation is checked first. Much of Greenwich sits within conservation areas, and some of it is listed, so permitted development rights are often removed here and careful design plus the right consents matter. We check your specific address before anything is drawn.
