True-scale layout editor

Design any world at true scale.

Drag rooms, furniture, doors and windows onto a real floor plan — a manufactured home, a restaurant, or the deck of a spacecraft. Every piece is its real size, in metres or feet, so what fits on screen fits in the room.

No account needed to design. Your layouts save to your own computer as .wdf files.

COMMANDER CLASS · 28 × 60 ft double-wide

Plan it the way it will be built.

Guessing at sizes is how a queen bed ends up blocking a closet door. World Designer uses real dimensions for everything, from the shell to the toilet.

1 : 1

True scale

Beds, counters, consoles and doors come at their real size, with door swings drawn so you can see the clearance.

m / ft

Metres or feet

Flip units any time. The grid snaps to a third of a metre, or to the inch when you work in feet.

Plugins

Each plugin adds a whole vocabulary: its rooms, props, doors and ready-made starter layouts.

.wdf

Yours to keep

Save a world as a .wdf file, open it again later, or export a PNG of the plan to share.

Featured plugin

Normal on the outside, starship on the inside. A spacecraft interior for a standard Canadian manufactured home.

Commander Spacecraft Deluxe

Templates and props for a manufactured home that would rather be a starship.

Official. General purpose. Deluxe. Marketing was very insistent.

  • Bridge with helm consoles, a command chair, a crash couch and a wall-size viewscreen
  • Galley and engineering, down to the fresh-air unit and a server rack for the GPU
  • Hydroponics hall with grow racks running between the crew berths
  • Airlock porch with a smart-glass wall that goes dark in Evening mode
  • Two templates: the Commander Class double-wide and the Scout Class single-wide
  • Build notes: what to order from the factory, and what to add after delivery

On the way

Being built now. Your account is where these will live.

Titan, your design advisor

Reads your layout against the rules that apply to it and tells you plainly what it implies: a missing clearance, a code minimum, not enough bathrooms for the crew.
