Commercial Fit-Out Forest Hill

Commercial fit-out in Forest Hill is small scale and close to home: a shop, cafe, salon or clinic in the Forest Hill District Centre, a unit near Forest Hill station, or a shop on a parade with flats above. The Lewisham Local Plan lists Forest Hill among the borough's District Centres, and that designation matters when a unit changes use. We strip out, build and fit these units, working to the landlord's lease, the approved drawings and building control, and hand back a space ready to trade.

For Forest Hill, 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 Forest Hill: 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.

The Forest Hill District Centre and the parades around it

Customer-facing units in Forest Hill sit in the District Centre and on the parades that run off it. The Local Plan status puts a shop or cafe inside a centre the borough wants to keep trading, and it bears on what a unit may become later. Check the Local Plan policies map for the centre boundary, because a unit on a side street may fall outside it, and check the lease for permitted uses before you commit. Expect a single ground floor unit rather than a whole building, often with homes above.

Moving between uses inside Class E, such as a shop becoming a cafe, clinic or gym studio, is not development and needs no planning permission unless a condition restricts it. A hot food takeaway, pub or bar is sui generis, so changing to one needs planning permission, and cooking needs extraction and odour control assessed with it. The fit-out itself tends to be a strip out of the last tenant's fittings, new counters, a WC, lighting, flooring and a shopfront refresh. An older Forest Hill unit can hide rotten joists, old service runs and damp at the rear wall, which are easier to repair while it is empty.

If the building is listed, the works themselves are a separate question: anything that affects its character, inside or out, needs listed building consent from Lewisham Council, and carrying it out without consent is a criminal offence.

Shopfronts and shutters on Forest Hill parades

A new shopfront has to follow Lewisham's design guidance. The Shopfront design guide SPD was adopted on 27 September 2006, and Policy QD11 says any necessary security should use internally located, open mesh security shutters and boxes. That weighs against a solid external roller shutter, which normally needs planning permission in any case, so we price an internal open mesh shutter behind the glass from the start. Its box sits inside too, so the fascia stays clean and a Forest Hill shop still shows at night.

A shopfront under Victorian upper floors frames the whole elevation, so surviving pilasters, consoles and stallrisers are worth keeping rather than boxing in. Replacing a shopfront in a way that changes the look of the building normally needs planning permission, which the owner or their designer applies for. Illuminated signs and fascias can also need advertisement consent. If the building is inside the Forest Hill conservation area, the application also needs a heritage statement. We build and install the shopfront to the approved drawings once the consents are in place.

Food, drainage, access and fire in a Forest Hill shop unit

A cafe or restaurant adds drainage and extraction to the fit-out. Grease from a commercial kitchen blocks the sewer if it goes down the sink, so a grease trap or other grease management goes under the wash-up area, sized to the menu. A new WC or wash-up sink in a Forest Hill shop is where drainage work begins, and Lewisham says a building control inspection is needed where a WC is installed or its position altered. The extraction duct route, and where it leaves the building, is settled on the drawings before the counter is fixed.

Access and fire safety decide where the counter and partitions go. Part M asks for a usable entrance and, where there is room, an accessible WC, and an alteration must not leave access worse than before. Part B covers escape from the shop floor and fire separation from the flats above, which is where much of the inspection effort sits on a Forest Hill parade. Fire stopping goes round every service that passes through the ceiling into the flat above, alongside fire rated construction and alarms.

Trading hours, deliveries and neighbours on a Forest Hill parade

A shop fit-out on a Forest Hill parade runs beside businesses that are still trading and homes that are still lived in. Lewisham allows noisy work between 8am and 6pm on weekdays and between 8am and 1pm on Saturdays, and none on Sundays or bank holidays. We put breaking out and drilling early in the programme, inside those hours, and hoard the frontage so neighbouring shops keep their doorways clear. The flats above hear everything through a timber floor, so residents get notice of the loud days.

Deliveries and waste need planning on a busy road. A skip on the road needs a licence and, in a controlled parking zone, a temporary parking suspension, applied for at least five working days before the start date. Counters, display units and shopfront glazing arrive on fixed dates, so we book loading around the parade's own delivery times. The landlord's consent to the works, and your duties as the client under the CDM Regulations, are settled before the first day on site.

The GS Renovation Difference in Forest Hill

Small commercial tenants lose money every week the shutters are down, so the programme comes first. We give you a written sequence from strip out to handover, order long lead items such as the shopfront and shutter early, and run our own trades back to back. We price from a site survey, not from photographs, so the problems in an old shell are found before you sign, and inspections are booked so fire stopping and drainage are seen before they are covered.

• Shopfront, sign and extract consents checked before anything is ordered
• Counter, display and back of house built by our own trades
