H3
An 11.5-metre cabin finished in the factory: a bedroom, a long living and dining space, a 2 m kitchen and a shower room, with the electrics and plumbing already in. Craned into place and connected the same day.
Ex VAT, delivered and installed within 150 miles of Alton. Groundworks quoted separately after survey.
Design yours in 3D.
Walk round your H3 and look inside. Choose the glazing, the layout, the kitchen and every finish, and watch the price as you go.
Or a quick figure
A rough price in a few choices. We confirm it against your site at survey; nothing here is binding.
Zones along one axis.
The plan runs end to end, with the services core placed so the wet room, kitchen and plant share a single floor penetration — one trench from the house, one connection on install day.
Layouts can be mirrored, and internal partitions can be dropped for an open-plan variant, without changing the shell or the price.
