Commercial Fit-Out Southwark

Commercial fit-out in Southwark covers shops, cafes, restaurants, salons and clinics on streets as different as Rye Lane in Peckham, the lanes around Borough Market and the borough's railway arches. The rules follow the place. Historic shop fronts in conservation areas are kept, a change of use in a town centre keeps a shop window, and an arch or a unit on a shopping frontage cannot quietly become a home.

For Southwark, published UK guides put refurbishing a retail space at £1,500 to £3,000 per m² and a restaurant or cafe at £2,000 to £4,500 per m², and London units usually cost more (MyBuilder, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Southwark: our own trades do the strip-out, back of house, counter fitting and finishes, and we coordinate the shopfront, extraction, electrical and fire specialists the unit needs.

Shop fronts on Rye Lane and other Southwark conservation streets

If your unit sits in a Southwark conservation area, or in a heritage asset, a traditional or historic shop front is kept and refurbished rather than ripped out. That is the effect of Policy P39 in the Southwark Plan 2022. Southwark's Rye Lane Peckham Conservation Area is centred on Rye Lane, Peckham Hill Street and Peckham High Street, so shops on those roads can fall inside it; check the boundary for your address.

In practice that means repairing the stallriser, pilasters, fascia and console brackets, and fitting new glazing within the old frame. P39 also asks for security grilles on the inside, and on a change of use within a town centre it asks for a shop window to be kept or put back. An external roller shutter runs against that, so the fit-out drawings show an internal grille behind the glass and a window display from the start.

Fitting out a Southwark railway arch for business use

A Southwark railway arch is fitted out as business space, because turning it into a home needs planning permission. Under the borough's Article 4 direction on Class E, changing a commercial building to a home needs permission across the CAZ, the railway arches, the town centres, shopping frontages, site allocations and strategic protected industrial land. A separate Article 4 direction removes the permitted development right for light industrial arches to become dwellings.

Arches suit cafes, bakeries, bars, gyms and workshops, but check the use class first: a cafe, gym or clinic sits in Class E, while a bar or pub is sui generis and needs its own planning permission. In the arch we line the brick vault against damp and noise, form a draught lobby at the entrance, run the services at high level along the crown, and install the glazed screen at the open end to your designer's scheme.

Kitchens, extraction and accessible WCs in Southwark units

A food unit in Southwark is planned around its kitchen extract and drainage before anything else. Hot food takeaways are sui generis, so a change to one needs planning permission, and a restaurant or cafe with cooking needs an extract and odour control scheme the planning officer and environmental health can accept. The duct route to roof level is often the hardest part of the design in a terrace with flats above.

Southwark takes shop and restaurant work on a full plans building control application, so the drawings for escape routes, fire separation from the flats above and an accessible entrance and WC under Part M are checked before we start. Where food is served, a grease trap on the kitchen drainage protects the sewer. Counters, display units and service areas are built to the approved layout, and floors are chosen to suit trading: slip resistant in kitchens, hard wearing at the door.

Trading streets, neighbours and deliveries in Southwark

Southwark's commercial units sit on busy trading streets, in markets and in parades with homes above, and the fit-out has to fit around all three. The London Plan town centre network runs from International and Metropolitan centres down to Local and Neighbourhood centres designated in Local Plans, and Southwark's Class E Article 4 direction reaches its town centres and shopping frontages. A unit in one of those places cannot switch to a home without planning permission, so plan the fit-out for trading.

On site that means planning around your neighbours. Next door shops keep trading, and the flats above are people's homes, so the loud strip out stays inside the council's hours of 8am to 6pm on weekdays and 9am to 2pm on Saturday. Deliveries come early before the street fills, and the landlord's consent for the works and your CDM duties as the client are in hand before the first trade arrives.

• Internal lattice grilles and shutters designed into the shopfront
• Commercial kitchen builds around the extraction specialist's canopy

Working With GS Renovation in Southwark

A shop or cafe opens on a fixed date with rent already running, so the order of trades decides whether that date holds. We settle the extract route, drainage and shop front details with your designer before strip out, fit the counters and service areas to the approved layout, and keep the loud work away from trading hours next door and the flats above. Before you open, the completion certificate, electrical certificates and extract commissioning records are gathered in one file.
