Expandable Tiny Homes
A galvanized-steel home that ships at 7′3″ wide and opens to almost three times that on site. Four sizes, from a 200 sq ft studio to a 790 sq ft family home — finished, wired, plumbed and customized.

Each unit travels as one container-sized box and unfolds into two side wings once it is set down. 10, 20, 30 and 40 FT models — about 200 to 790 sq ft, on a slab or pylon foundation, customizable from A to Z.
Configure your unit
It ships compact. Then it opens.
A double-wing expandable home is a fixed steel core with a folding wing on each side. On the truck it is the width of a shipping container. On site, the two wings swing out — floor, walls and roof together — and the home grows from 7′3″ to about 20′6″ wide.
Inside it is a real, finished home: a full kitchen, separate rooms, a complete bathroom and a proper living area. Everything is built and fitted in the factory, so the work on your lot is measured in days, not months.
Pick your footprint.
Four models on the same expanding system, all 8′2″ tall outside. Place one on its own, or set two or more side by side for something larger.

Delivered, opened, connected.
The foundation goes in
Before the unit arrives, we prepare the base — a poured concrete slab or a set of concrete pylons, depending on your ground and how permanent you want it. It's shallow, quick, and far less invasive than a conventional footing.
The unit is delivered folded
The home arrives on a truck at container size. A crane hooks into the lifting points built into the frame and sets it onto the foundation in a single lift.
The wings open out
Each side wing is drawn outward, and its floor, walls and roof lock into place against the steel core. Nothing is assembled panel by panel on your lot, and every moving joint is sealed with weather strips and butyl tape.
Hooked up and finished
Water, power and waste are connected, final trim is done, and the unit is handed over ready to use. Off-grid setups with solar and tanks are available where there's nothing to connect to.
