When Standard Sizes Are Not Enough

Custom Gym Box — office + gym installation in a forest setting

The Gym Box 7×5 (35 m²) is the largest model in our standard range. But some projects require more space, a different footprint, or a configuration that a single module cannot deliver. That is what the custom programme is for.

A bespoke Gym Box is built from container modules combined into whatever configuration the project demands:

Two modules side by side – e.g. 11×6 m = 66 m² (shared wall removed, open-plan interior) ➜ Two modules in an L-shape – separate zones within a single structure ➜ Two-storey module – gym on the ground floor, changing room or office above ➜ Module with terrace – glazed end wall opening onto a decked outdoor area
