Warehouse fit-out FAQs

Can you fit out a warehouse while it is still operating?

Yes. Most of our warehouse projects are live sites. On the Banbury warehouse we built new welfare and storage in 4 weeks around continuing operations.

What is the difference between a warehouse fit-out and a refurbishment?

A fit-out adds what your operation needs inside the building — offices, welfare, racking, power. A refurbishment repairs and upgrades the building itself — floors, roof, lighting, heating. Most projects combine both.

How long does a warehouse fit-out take?

Smaller fit-outs of 100–500 m² typically take 4–8 weeks on site. Larger or phased projects take longer. You get a fixed programme with your cost plan.

Do you work outside London?

Yes. We are based in London and deliver warehouse projects across the South East and the Midlands, such as Banbury in Oxfordshire.

What is the minimum project size?

Craftex takes on construction projects from £100k.
