How much does a modular office cost?
A modular office's cost depends on desk count, meeting rooms or partitions, kitchenette and WC provision, data and electrics, and site access. Build the layout online to see its total.
Offices are the most common thing we build, from a single room in a yard to a two-storey block inside a warehouse. Because modules join side by side and stack, you can size the building to the headcount rather than the other way round.
Typical configurations
Choose the mix of unit sizes and fit-out you need. The designer shows the final total for that exact configuration.
| Modules | What it realistically fits |
|---|---|
| 1 module | 2–4 desks, or a single private office |
| 2 modules | 6–8 desks with a tea point |
| 4 modules | 12–16 desks, WC and kitchenette, or a mix of open plan and one meeting room |
| 6 modules | About 20 desks with WCs, kitchen and a meeting room |
| 8 modules | Larger office with separate meeting rooms, accessible WC and staff break area |
