Commercial fit-out
White box fit-out in London
What the landlord hands over, what your fit-out adds, and the approvals in between.

A white box unit gives you a clean starting point, but not a finished shop. Before you sign the agreement for lease, it pays to know exactly what the landlord hands over, what your fit-out has to add, and which approvals sit in between. Our Treelogy and 60 Degrees Coffee fit-outs both started from white box units in managed buildings.

Between handover and opening
A white box is a starting point, not a shop.
Services, counter framing, finishes and the landlord’s approvals all sit between the empty unit and the day you trade. We read the fit-out guide before we price any of it.

Before you sign
Questions to ask the landlord
- Handover specification
- Ask for the written white box specification. Check where services are capped and whether the electrical supply is enough for your equipment.
- Fit-out guide
- Most managed buildings have one. It sets working hours, noise limits, deliveries, insurance and how fire alarm work is carried out.
- Licence for alterations
- Find out who reviews your drawings, how long approval takes, and whether you pay the landlord’s surveyor and legal fees.
- Rent-free period
- Compare the rent-free period with a realistic programme for approvals, equipment lead times and the build.
- Reinstatement
- Check what you must remove at the end of the lease. It affects how you build the fit-out.
Questions
Questions about white box units
What is the difference between shell, white box, Cat A and Cat B?
A shell has little more than the structure and a supply to the building. A white box adds finished walls, a basic floor and capped services, and is common for shops and cafés. Cat A is the office equivalent, with ceilings, lighting and air conditioning in place. Cat B is the occupier’s own fit-out on top of Cat A.
How much does it cost to fit out a white box coffee shop?
Our planner gives £135,000 to £201,000 for a 750 sq ft coffee shop from white box at a standard finish, including equipment, contingency and VAT.
Can you review the landlord’s pack before I sign?
Yes. Send us the fit-out guide and handover specification with your enquiry, and we will point out anything likely to add cost or time.
