Designing for a crew we would never meet
The under-floor plumbing and electrical runs were finished and pressure tested in the factory, and every outlet was capped and labelled. On site there is no joinery, no chasing and no guesswork: the crew pulls the services into the wet wall and connects.
Foundation: the part clients underestimate
These units do not need a slab, but they do need four points that stay level. On gravel that means compacted pads under each corner rather than blocks dropped on the surface. It is half a day of work and it is also the single most common reason a door stops closing six months later.
Insulation for a rental, not a home
Rental cabins here are occupied in bursts, so the sensible money goes into the walls rather than into thermal mass: rock wool panels to stop the interior swinging between a hot afternoon and a cold night. Flooring stayed PVC — easy to replace between guests and untroubled by wet boots.
What we would repeat
Film the first unit being unfolded on a phone at the factory, with the unit number taped to the wall. Both units were identical, so the second crew watched the first go up and finished in six hours. It cost twenty minutes of filming.
