Building work in Bermondsey: area guide

This is our area guide to building work in Bermondsey (SE16, SE1, Southwark): the housing, the council rules that apply (Southwark Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Bermondsey.

In Bermondsey the job is usually a fit out inside somebody else's structure. Most SE16 homes are flats in post-war estates and newer blocks; the converted warehouses off Bermondsey Street keep load-bearing brick shells around timber or iron floors, the newer riverside blocks towards Southwark Park are framed in concrete, the flats within them are leasehold, and the walls you want to move may be doing nothing structural at all while the one you assumed was a stud is a shear wall. GS Renovation works across SE16 on apartment fit outs and internal reconfiguration, dealing with managing agents, block rules and Southwark Council building control where the work is notifiable.

Take the 27,150 or so homes the valuation list gives Bermondsey: 89% flats, 11% houses, 9% from before 1919, 12% interwar and 73% post-war. VOA Council Tax stock of properties, March 2025, for all 6 statistical areas in Bermondsey. Counts rounded by the VOA.

Partitions, cores and slabs: what can move inside a Bermondsey frame

In a frame building the loads travel down columns, cores and slabs, so most internal partitions are non structural and come out without any beam: an open-plan conversion job, not a steel one. The exceptions matter enormously. Concrete walls around lift shafts and stairs usually stabilise the whole building, and a doorway into one is a structural alteration job for the engineer, not a site meeting. Slabs are another red line, because chasing into a post tensioned floor to sink a drain or a cable can sever a tendon with consequences well beyond your flat.

So we establish the structure before the design is fixed. Where record drawings exist, the managing agent normally holds them. Where they do not, the structural engineer we appoint surveys and advises, and anything touching the frame gets a design we build to, never a judgement made on the day. Weight is checked too. Stone worktops, a walk in shower tray on a raised plinth and a screed thick enough for underfloor heating add up, and slabs have a loading limit, so on a kitchen renovation or bathroom renovation we confirm the loading position before heavy finishes are ordered.

Leases, licences and block logistics set the SE16 start date

Before a tool comes out of the van, the paperwork chain has to be settled. Most SE16 leases require the freeholder's licence to alter for anything beyond decoration, and the freeholder's surveyor will want drawings, a method statement, our insurance details and often an undertaking on costs. Leases commonly specify floor coverings as well, requiring carpet or a rated acoustic underlay over a defined proportion of the flat, which is worth reading before you fall in love with engineered oak throughout. We read the lease with you before pricing rather than afterwards.

Then there is the building itself. Working hours are set by the management company, the goods lift is booked in slots, which governs how a new kitchen arrives, protection goes down over communal floors and lift interiors, and waste leaves in bagged loads through a route agreed with the concierge rather than into a skip at the kerb. Deliveries around Maltby Street Market and the narrow approaches to Bermondsey station need timing. We plan all of it in so the flat below never becomes the reason a week is lost.
