One trailer. Eight feet wide. Every square foot has a job to do. Frame the shell, cut the light in, furnish the floor — then see if your build passes inspection. Small house, big call-sheet.
| Frame | Pick the trailer length, roof line and sleeping loft. A pitched roof (gable or shed) is what makes room for a loft; skylights bolt onto any roof. |
| Openings | Choose a door or window, then tap a wall to cut it in. Every pane raises your daylight score — and adds weight. Tap with the eraser to patch a hole. |
| Furnish | Pick a piece, tap the floor to set it down, ⟳ (or R) to rotate. Tap a placed piece to pick it up again; 🗑 (or Delete) sends it back. Keep a clear path from the door. |
| Paint | Siding, trim, roof and floor. No wrong answers. Some more right than others. |
| Job card | The inspector wants seven things: somewhere to sleep, cook, bathe, eat & work, some heat, some storage, and a door you can actually reach. Watch the trailer load bar — axles have limits — and keep the level bubble centered by spreading weight along the build. |
| Share | The ↗ Share button packs your whole design into a link or a short code — send it to anyone and it opens right in their studio. You can also download a .json of the build or save a photo. |
Five finished builds, five different answers to the same eight-foot question. Open one and remodel it however you like — your own build stays safe until you edit.
