01Platform

A small structure, set exactly where it should stand.

FOSS — Forward Operating Sauna System — is a modular, container-based sauna built for places with few ways in.

It arrives whole. It sits light on the ground. It is taken away without a trace.

Built for the far north — fjord, ridge, deck and ice.

Offshore & energy

Crew welfare on platforms and remote sites. Marine-rated, helideck-sling compatible.

03

Remote hospitality

The retreat segment. Narvik, and the run-up to the 2029 championships. Quiet luxury, far from the road.

04Reversibility

Reversible by design.

Brought in by boat. Set on ground screws. Removed without a trace.

No concrete, no scar. The site returns to what it was.
