I need an office for 20 staff inside my warehouse. What are my options?
Twenty desks needs roughly 40–60 m² of office, which is four to six joined modules at £43,000–£64,500 + VAT, delivered finished and stood inside or alongside the warehouse. Stud partitioning is cheaper but permanent and noisy to build; a mezzanine buys floor area but triggers structural and fire-safety work.
Warehouse offices usually start as a corner of the floor plate with a few desks. The pinch point is heating, noise and daylight — a partitioned corner of a shed is rarely somewhere twenty people want to work all week.
Your options compared
Modular office units
Insulated, finished modules joined to the size you need, inside or outside the building.
- Insulated and heated independently of the warehouse
- Arrives finished, so no trades working around your operation
- Can be moved or added to as headcount changes
- Needs clear floor space and access to get the modules in
- Power and data need bringing to it
Stud partitioning
Building office walls directly inside the warehouse envelope.
- Lowest initial cost
- Uses the existing roof and floor
- Weeks of trades on site
- Inherits warehouse noise and temperature
- Hard to remove or reconfigure later
Mezzanine floor
A raised deck with offices above, keeping the floor area below.
- Keeps ground-floor operational space
- Good use of headroom
- Structural design, fire protection and building regulations
- Significant on-site programme and cost
For twenty staff, a joined modular office gives you a proper working environment quickly, without tying the space up permanently. If you rent the warehouse, it is also the only option you can take with you.
