Two-Storey Modular Buildings
Stacking modules doubles the floor area without widening the footprint. It is the usual answer on a tight yard, a narrow plot or anywhere the ground-floor area is already spoken for.

What stacking changes
The module itself doesn't change — the base, the structure and the stair arrangement do. Every two-storey project is reviewed for foundations and structure, and services are stacked vertically wherever possible.
- Twice the floor area on the same footprint
- Internal, external or covered external stairs
- Roof terrace formed over any exposed ground-floor module
- Vertically aligned services to simplify connections
- Foundations and structure reviewed per project
- Ground floor can stay open-plan while the first floor is partitioned
Typical arrangements
Two modules per floor — a common office or home arrangement.
Three per floor, with a terrace over an exposed ground module.
A full two-storey building with stairs and first-floor facilities.
