Office Fit-Out Streatham

Office fit-out in Streatham is small-scale work to expect: a suite on an upper floor of Streatham High Road, a room above a shop near Streatham station, or a professional office in a converted period building. The Lambeth Local Plan names Streatham a Major Centre, but away from the High Road this is a residential district, not a business one. We strip out, build partitions and ceilings, and fit lighting, power and kitchenettes to your landlord's consent and the approved drawings.

For Streatham, the construction part of an office fit-out is published at £70 to £120 per sq ft as a UK guide, and an all-in London office fit-out at £148 to £359 per sq ft (Oktra and Cushman and Wakefield, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Streatham: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

What office space in Streatham actually looks like

Expect upper floors and small suites here rather than purpose-built office blocks. Lambeth identifies Brixton and Streatham as its Major Centres, and Policy ED1 supports large offices of 1,000m2 or more in the Brixton and Streatham major town centres. In practice a Streatham fit-out is likely to be a first or second floor above a High Road shop, reached by its own side door and stair. The other common case is a ground floor suite in a building that began life as a house.

That shapes the brief. Upper floors over shops tend to have one stair, timber floors, limited headroom under the roof and services that were added in stages over the years. We survey the floor loadings, the stair, the existing distribution board and the ceiling void before a layout is drawn. That way partitions, meeting rooms and a tea point go where the building can take them, and the cabling routes are known before your IT supplier arrives.

Cat A and Cat B fit-out for a Streatham office suite

Cat A is the landlord's base finish: ceilings, lighting, heating and cooling, small power to the floor, and toilets, ready for any tenant. Cat B is the tenant's own layout on top of that: partitions and glazed screens, meeting rooms, a kitchenette, furniture power, signage inside and the decoration that makes the space yours. A small Streatham suite may be let in neither state, so the first job is agreeing which items the landlord delivers and which fall to you.

A typical sequence runs strip-out, first fix of electrics and any new water and waste for a kitchenette or shower, partitions and ceilings, second fix and lighting, floors, then decoration. Data cabling is run by your IT supplier during first fix, with containment we provide in the ceiling or skirting. Glazed screens and doors are measured on site after the partitions are up, because period walls are rarely square and a screen made to drawing dimensions alone will not fit.

Lambeth building control and fire safety for Streatham offices

An office fit-out that changes partitions, escape routes or services goes through a full plans application in Lambeth. Its building control service says works to commercial properties need full plans, ideally sent at least five weeks before work starts, and it uses that application to consult bodies such as the fire authority. For an upper floor office the questions are the means of escape down one stair, fire separation from the shop below, and alarm and emergency lighting.

Part M asks for reasonable access and a usable WC, which is hard on a narrow stair above a shop, so the drawings should record what is achievable. Part L applies to new lighting and controls. As a commercial client you have duties of your own under the CDM Regulations, including appointing a principal designer and principal contractor where more than one contractor is involved. We work to the approved drawings and leave fire stopping open for inspection before ceilings close it in.

Planning background, working hours and lease end for a Streatham office

Streatham town centre is covered by one of Lambeth's three Modified Article 4 Directions on Class MA, in force since 28 October 2022, so offices inside the direction's boundary cannot switch to flats under permitted development. Modified Direction 3 names Streatham town centre among the locations where that right is withdrawn. For an office tenant this is background: turning those floors into flats needs a planning application rather than a prior approval.

Lambeth allows building work Monday to Friday 8.00am to 6.00pm and Saturday 8.00am to 1.00pm, with none on Sundays or bank holidays. Noisy work in an occupied building is planned inside those hours and quiet tasks such as decoration are agreed with the landlord. Keep a record of the fit-out drawings, because at lease end the landlord may ask for reinstatement under the dilapidations clause, and knowing what was added makes stripping it back simpler.

The GS Renovation Difference in Streatham

A small office needs the work finished without losing weeks of trading. We start from a survey of the floor you have taken, agree with you and the landlord which items are Cat A and which are Cat B, and give you one programme from strip-out to handover. Partitions, electrics, plumbing for a kitchenette and decoration run under one site lead, and fire stopping stays open for building control to see before it is covered. You speak to one person throughout.

• Materials priced at options, so you choose the finish
• Full plans building control coordinated for the new office layout from the outset
