Building work in Deptford: area guide

This is our area guide to building work in Deptford (SE8, Lewisham): the housing, the council rules that apply (Lewisham Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Deptford.

Deptford is layered in a way that few London neighbourhoods are, and the first job is reading which layer a property belongs to. There are early terraces of soft brick near Deptford High Street, some of them protected, some barely touched since they were built. There are former industrial buildings by Deptford Creek converted into flats, and there are the post-war estates and newer blocks that hold most of the housing, so flats, on VOA figures, are the norm. Then there is everything squeezed in between. GS Renovation works throughout SE8 without holding premises here, and appoints structural engineers rather than producing calculations.

Deptford's housing, as the Council Tax list records it, is about 14,290 homes: 15% houses, 85% flats, with 9% pre-1919, 4% interwar and 84% built since 1945. VOA Council Tax stock of properties, March 2025, for Deptford North, Silwood & Pepys and New Cross & Deptford South. Counts rounded by the VOA.

Early brick houses near the High Street need their status settled first

The oldest houses in Deptford were put up in soft handmade brick bedded in lime, with timber lintels over openings and floor joists running deep between the front and rear walls. They move, they breathe and they punish hard modern materials. Cement pointing and impermeable paints trap moisture behind the face of the brick and spall it off over a few winters, so repairs here use mortars that suit the wall. For RSJ installation the temporary support is the difficult part rather than the beam, and the engineer we appoint sets that arrangement out.

Status has to be established before design. Where a house is listed, listed building consent may be needed for internal changes as well as external ones, which puts chimney breast removal, original partitions and joinery outside the scope of a site decision. In a designated conservation area, side, two-storey and roof additions lose their permitted development rights and materials are scrutinised. We confirm the position with Lewisham Council for your particular address, then build to what is approved, with building control applications and inspections coordinated in parallel, since the two consents run alongside rather than replacing one another.

Warehouse conversions by the Creek start with the freeholder's licence

A converted industrial building behaves nothing like a house. The frame carries the loads, the external brick is often just an envelope, floors may be concrete rather than timber and internal walls are usually metal stud that carries nothing. That makes an open-plan layout surprisingly free, provided the assumptions are verified from the building's drawings or by a structural engineer rather than by tapping a wall. A mezzanine, a new opening in a concrete slab or heavy fittings hung from a frame are structural alteration jobs, not carpentry, and need the freeholder's licence to alter before anything else.

Then there are the house rules, which in a converted block are usually detailed and firmly enforced: working hours, a booked goods lift, a deposit held by the management company, no waste left in communal areas and a delivery route that avoids the residential entrance. Acoustic separation under Part E is the one owners underestimate, because concrete transmits impact noise readily, and a new hard floor in a kitchen renovation without the right resilient layer will be heard below. We plan around the building's constraints and coordinate the building control notifications.
