Office Fit-Out Deptford

Office fit-out in Deptford is small-scale work, and it helps to say so up front. This is not a business district: the offices here are rooms above shops on the High Street, small suites in the District Centre, and studios and workspaces in the older industrial buildings along Deptford Creek. We fit out that kind of space for a business taking a new lease or reshaping the one it has, working to your landlord's licence and to building regulations for non-domestic work.

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

The office space Deptford actually has

Deptford's workspace is a mix of upper floors and converted industrial buildings rather than office blocks. The Lewisham Local Plan lists Deptford among the borough's District Centres and names Deptford District Centre as a Regeneration Node, so the High Street and the streets around it hold the professional offices, practices and small firms. Many of them occupy a first or second floor reached by its own stair beside a shop, with a small floor plate and windows to the street.

Along Deptford Creek the space is different. The Deptford Creekside conservation area was designated in May 2012 and covers industrial Creekside south of the railways and the Crossfield Estate. Studios and workshops there sit inside brick or steel framed buildings, where the shell stays and a new insulated lining, partitions, lighting and services go inside it. We look at which of the two you have before we plan a layout or a programme.

Cat A and Cat B fit-out in a Deptford office

The first question on a Deptford office is how much the landlord has already provided. A Cat A finish is the landlord's base: open floor, ceilings, lighting, small power at the perimeter, heating and cooling, and working WCs. A Cat B fit-out is what makes it your office: partitions and glazed screens, meeting rooms, a tea point or kitchenette, floor boxes, lighting set to your desks and your own decoration and signage inside.

In an upper floor on the High Street, the Cat A often needs work before Cat B can start, because the space may have been a store, a flat or a tired office. We strip out, repair the ceiling and floor, and upgrade the lighting and power, then build your layout. Data cabling is coordinated with your IT supplier: we provide the routes, the floor boxes and the containment, and they install and test the network so it is theirs to support.

Building control and site duties on a Deptford office fit-out

Office work in Deptford is non-domestic building work, and building regulations reach further into it than most tenants expect. New partitions change escape routes and fire separation under Part B, a new WC or entrance raises access under Part M, and new lighting and heating fall under Part L. Lewisham's own inspectors visit sites to check that building work complies with building regulations, fire safety, energy conservation and access, so those items are drawn before we start.

On a full plans application, Lewisham Building Control sends its decision within five weeks unless the applicant has given a three week extension, and that time sits in your programme. Under the Construction (Design and Management) Regulations a commercial client has duties of its own, including allowing time and resources and appointing a principal designer and a principal contractor in writing where more than one contractor is on site. We act as principal contractor on those jobs. We run the site under a construction phase plan and explain what the regulations ask of you.

Deptford offices and the Class MA Article 4 direction

An office owner in Deptford District Centre can no longer turn the space into flats under permitted development. Class MA of the General Permitted Development Order 2015 permits a change of use from Class E to Class C3, but Lewisham set 01 November 2025 as the date its Article 4 Direction removing that right comes into force. The direction covers Major Centres, District Centres, Local Centres, Strategic Industrial Locations and Mixed-Use Employment Locations, so Deptford District Centre is inside it.

For a tenant fitting out a Deptford office this is background rather than a hurdle. It helps keep upper floors in the centre as workspace, which is the supply you are choosing from, and it means a landlord is less likely to plan a residential scheme over your lease. Your fit-out itself needs no change of use while the space stays in office use, unless a planning condition says otherwise.
