Every part of the building, cut and drilled, stacked on pallets. It bolts together — there is nothing to weld and nothing to frame on site. An elevated structure with permeable floor: it stands clear of the ground, with open space underneath. Drainage is available at every point of the floor, not at a few fixed ones — so the three rooms go where you want them, and can be rearranged later. Power from your own roof, water from your own catchment, a building you own outright and can take with you.
One size: 650 sq ft, $130,000. That is the price of the parts on the truck. No foundation needed. Freight, assembly labor, and interiors are priced separately — see below.
The structure is identical. What changes is what the climate does to it and what your jurisdiction asks of you — and those two things do not line up the same way in Phoenix and in Honolulu.
Built for heat and dry air, on land where the rules are often lighter than the sun.
Built for rain, humidity, hurricane wind, and everything on an island that eats wood.
Most kit companies bury labor in the sticker price and hope you don't ask. We price the parts, the hands, and the fit-out separately — so you can do two of the three yourself and keep the money.
Everything on the manifest, palletized and ready for a flatbed — permeable floors included. Fixed price, fixed scope, no allowances.
Assembly help, at the level you need it. Three people and a lift can stand the frame; you decide who those people are.
What goes inside the shell, once it's up and your approvals are in hand. Quoted separately when you want it.
Read this before you buy anything from anyone. A kit company that won't show you this table is hiding the expensive half.

The Pavilion stands on steel, clear of the ground, and its floor is open-jointed composite on steel joists. That combination is what frees the plan: drainage is available at every point of the floor rather than at a few fixed ones, and there is open working space underneath the whole building. The three rooms, the walls between them, and any wet zone sit wherever you want them — and sit somewhere else after you have lived in it a year.
Frame, panels, permeable floor, three partitioned rooms. Office, studio, gym, shop, guest space.
Lighting, power, a mini-split, sliding doors. Still dry. Still bolted. Still comes apart.
Bathroom pod, kitchen run, service connections — sited wherever the plan wants them, and reached from the open space under the building. No pan to build and no membrane to lay.
Where the code path exists, the structure can take it. Available on the Desert configuration.
No foundation needed. Nothing is poured, and no ground is disturbed. No impervious cover is added. There is no septic to review, because there is no plumbing.
What applies to your parcel is set by your county, not by us. Tell us where the land is and we will tell you what to check.
Check my county →Every dependency a normal house carries — the power company, the water main, the sewer line, the lender, the lot it can never leave — is one this building can do without. Sovereignty here is material, not legal: you still follow your county's rules. You just stop needing anyone's grid.
Steel frame and sloped metal roof take PV mounting. Array and batteries by owner.
Sloped metal roof and eave flashing suit rain catchment. Gutters and tanks by owner.
Elevated structure. Runs go anywhere under the floor and stay accessible.
Bought outright, not financed for thirty years. It unbolts and moves to the next piece of land with you.
The base kit is a dry shell — no permanent plumbing, no built-in kitchen. That is what keeps the first step small and the freight cheap.
Steel frame, steel-skinned panels. No structural wood in the kit.
Every connection is a torqued bolt you can inspect, and a bolt you can undo.
Steel and composite are not food for termites and do not rot the way timber does.
Every connection is a bolt. A kit can go back to being a kit.
It is designed to be assembled by a small crew with a lift for the roof panels. If that is not your line of work, buy Line 02 instead.
Impact driver, drill, sockets, a laser level, a come-along for squaring, and lift access to the eave. A tool list is available before you order.

No. The building is elevated and the floor is permeable, so no spot is more serviceable than any other and you can work underneath it. Move a wall, move a bathroom, turn the third room into a kitchen.
