Office Fit-Out Southwark

Office fit-out in Southwark splits into two very different kinds of job. In SE1, near the South Bank and Borough Market, offices inside the borough's part of the Central Activities Zone are covered by Article 4 directions, so they cannot become homes without planning permission. Further south, in Camberwell, Peckham and Dulwich, office work means smaller spaces: a floor above a shop, a professional suite or a studio. Where Southwark Council handles building control, both go in on full plans, and a leased floor needs the landlord's licence first.

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

Office floors and Article 4 in Southwark's Central Activities Zone

An office in Southwark's part of the Central Activities Zone cannot become a home without planning permission. The borough's CAZ Article 4 directions require a planning consent before an office or other commercial or leisure premises becomes a home. A separate non-immediate Article 4 direction, in force from 1 August 2022, removes the Class MA right to change offices in Class E(g)(i) to dwellings where it applies, so check the direction map for your building.

For a tenant this is background rather than a hurdle, but it explains the stock. Office floors covered by the directions stay in workplace use, so landlords refurbish them between lettings and incoming tenants fit them out again. A Cat A fit-out leaves the floor with finished ceilings, lighting, raised floor and heating and cooling, ready to let. Cat B is the tenant's layer on top: partitions, meeting rooms, a tea point, furniture and data, planned to your way of working.

Full plans building control for a Southwark office

If Southwark Council is your building control body, an office fit-out goes in as a full plans application. The council keeps the building notice route for small and simple domestic jobs, and rules it out for offices, shops and other workplaces. A registered building control approver is the alternative, and a purely decorative refresh with no change to escape routes or services may need no approval at all, so confirm the route with the designer first.

Full plans means the drawings for escape routes, fire separation, ventilation, accessible toilets and lighting are checked before the build starts. New partitions can lengthen a travel distance or block a route to the stair, so Part B shapes the layout. Part M covers access and WCs, and Part L covers lighting and controls. For you, it moves decisions forward: the partition plan, door swings and ceiling services have to be fixed early.

Small offices above shops in south Southwark

Away from SE1, an office fit-out in Southwark is more likely to be a small job, and it is honest to say so. Around the shopping streets of Camberwell, Peckham and Dulwich, the office space that comes up is an upper floor over a shop, a converted house used by a practice, or a studio. These jobs are simpler, but they share an entrance or a stair with other uses.

That shared stair is the key design question. An office above a shop may need fire separation from the unit below and a protected escape route, depending on the layout the designer and building control agree. Services are often old and shared, so we trace the supply, fit new lighting and small power, and coordinate data cabling with your IT supplier before ceilings close. A tea point and a WC are usually the only wet work.

Working hours, CDM and lease end in a Southwark office

In an occupied Southwark building, noisy fit-out work stays inside the council's hours: 8am to 6pm on weekdays and 9am to 2pm on Saturday, with none on Sundays or bank holidays. Quiet tasks such as cabling or decoration can often run in the evening by arrangement with the landlord. The landlord's licence for alterations sets its own conditions, so we read it with you, clause by clause, before the programme is fixed.

As a commercial client you carry duties under the Construction (Design and Management) Regulations, and where more than one contractor is on site a principal designer and a principal contractor are appointed in writing. Plan for the end of the lease too. Dilapidations clauses often require the tenant to strip out partitions and reinstate the floor to its original state, so we record the as found condition and keep your fit-out easy to remove.

• Dilapidations and reinstatement works at the end of an office lease
• Tea points and kitchenettes on the existing risers
• Strip-out of the previous tenant's office, with disposal

Trusted Office Fit-Out in Southwark

An office fit-out has a move-in date that cannot slip, so the sequence matters more than anything. We work from your designer's approved drawings, keep the building control inspections in the programme, and schedule noisy strip out inside the permitted hours while the rest of the building keeps working. You get one team for partitions, ceilings, lighting, joinery and finishes, with electricians and ventilation engineers certifying their own work before handover.

• Lease reinstatement clauses read before any partition is fixed to the structure
• Clean, tidy and reliable tradespeople
• Asbestos survey checked before any office ceiling, floor tile or boxing is disturbed
