Office Fit-Out Lewisham

Office fit-out in Lewisham is small scale work. The London Plan names Croydon, not Lewisham, as the strategic outer London office location. Office work here is small: floors above shops, small suites, studios and professional rooms, with the Lewisham, Catford and Deptford centres the obvious places to look. We strip out, build partitions, ceilings, lighting and small power, and hand back a workspace that meets the building regulations for non-domestic use.

For Lewisham, 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 Lewisham: we build the office partitions, ceilings, lighting and finishes as one contract and coordinate the IT supplier and specialist trades around them.

Where office space is found in Lewisham

The Lewisham Local Plan names Lewisham and Catford Major Centres and Deptford District Centre as Regeneration Nodes. Those centres, with their upper floors over shops, former banks and small suites near the stations, are the obvious places to look for office floor space. London Plan Policy E1 names Croydon town centre as the strategic outer London office location. An office fit-out in Lewisham is therefore more likely to be one floor or one suite rather than a whole building.

Deptford has a second kind of workspace. The Deptford Creekside conservation area was designated in May 2012 and covers industrial Creekside south of the railways and the Crossfield Estate. Studios and small workshops in older industrial buildings there need a different approach from a suite over a shop: exposed services rather than suspended ceilings. External changes there, such as new windows, vents or plant, are also judged against the conservation area's character.

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

Cat A is the landlord's base finish: ceilings, lighting, raised floor or trunking, heating and cooling, and toilets, with the space left open. Cat B is the tenant's layout on top of it: partitions and glazed screens, meeting rooms, a tea point or kitchenette, extra small power, signage inside and decoration. In a small Lewisham suite over a shop the line between the two is often blurred, so we list which items the landlord has provided before pricing the rest.

Timing is the other constraint. Lewisham restricts construction noise to 8am to 6pm Monday to Friday and 8am to 1pm on Saturdays, with no work on Sundays or bank holidays. In a building where the shop below or the other tenants keep trading, the noisy strip out has to fit those hours and the landlord's rules. Quieter work such as data cabling, which we coordinate with your IT supplier, can be arranged around the business.

Building control on a non-domestic fit-out in Lewisham

An office fit-out is non-domestic building work, so the building regulations look at different things than in a home. Part B covers fire and means of escape, including how new partitions affect travel distances and whether a meeting room creates an inner room. Part M covers access and accessible WCs, and Part L covers lighting and services. Where Lewisham is the building control body, its inspectors visit sites to check compliance with building regulations, fire safety, energy conservation and access.

Lewisham says that once a building notice is submitted, work can commence within 48 hours, but that route is not open for workplaces covered by the fire safety order, which an office is. A fit-out therefore goes through full plans with Lewisham or through a registered building control approver. On a full plans application Lewisham Building Control sends its decision within five weeks unless the applicant has given a three week extension. We build that into the programme before the strip out starts.

Leases, CDM duties and the Class MA picture in Lewisham

Before any work, an office tenant needs the landlord's licence for alterations, which usually asks for drawings and a method statement. The CDM Regulations give a commercial client duties of its own, including allowing enough time and appointing a principal designer and principal contractor where more than one contractor is involved. At the end of the lease, dilapidations may require the space to be reinstated, so we record what was there at the start.

Some of the office stock now has planning protection. Lewisham's Article 4 Direction removing the Class MA right to change Class E premises to residential was set to come into force on 1 November 2025. It covers Major Centres, District Centres, Local Centres, Strategic Industrial Locations and Mixed-Use Employment Locations. This does not change what a tenant may do inside an office, but it makes it harder to turn offices in those areas into flats.
