    Modular Building Sizes Explained

    Adacon modular buildings use P300, P400 and P600 units with external lengths of 2.9m, 3.9m and 5.9m, a common 2.2m width and 2.40m external / 2.16m internal height. The sizes can be combined to create more tailored floor areas and building shapes, joined side by side or stacked to two storeys subject to the final project design.

    How to size a building

    Work from occupancy and function rather than from a square-metre target. A single module comfortably takes a two to four person office, a WC and shower block, or a garden room. Once you need separate rooms, circulation or facilities for more than a handful of people, you are into multiple modules.

    Keeping numbers consistent

    The final total is based on the exact mix of units, layout, openings and fit-out. Transport, groundworks, drainage and final connections are quoted separately for the site.
