Flexolution II: modular building for retail, showroom or classroom space

The Flexolution II is a temporary building in the successful Flexolution range. Fully modular and demountable, it is ideally suited to use as a temporary supermarket, showroom or classroom; quick to construct, flexible, sustainable and reusable. Depending on size and layout, the Flexolution II can be erected within a few days or weeks and is easy to relocate. Like the Flexolution III, the Flexolution II is compliant with Building regulations and optimally insulated.

Modular building in terms of dimensions and design

The Flexolution II comes in 12, 15 or 18 metre widths. The length can be extended infinitely in 6-metre grids and the standard width increased by interconnecting structures. Available with a clear internal height of 2.4 or 3.4 metres. With an internal height of 2,4 metres, the modular Flexolution II can be built with one or two floors.

Just like a permanent building, the Flexolution II can be fully fitted out according to your requirements. Options include washroom facilities, kitchen units, interior fittings, lighting, heating, air conditioning, a range of floor coverings and industrial doors.

Sustainable and reusable materials

All the materials used in the Flexolution II are sustainable and reusable. The main structure comprises aluminium columns and laminated wooden beams. Meanwhile, the floor is constructed of a combination of steel beams and insulated wooden floor panels. Insulated sandwich panels make up the walls and roofs. The bolt-together assembly of the modular structure means there is no sawing or drilling is involved, which allows all parts to be reused after disassembly.
