Room Planner
Design a room — or a whole home — in your browser: draw walls in 2D and rooms are auto-detected, then add doors and windows, drop in real-size furniture and choose a floor material per room. Switch to 3D to walk through the plan, and export an image or the plan as JSON. This planner is a design aid, not a substitute for professional architectural, structural or safety advice; verify dimensions on site. All processing runs locally in your browser. Your data is not uploaded to any server. 100% Local
How to Use the Room Planner
Draw walls with the wall tool — endpoints snap to the grid, other walls and corners. Closed walls are detected automatically as rooms, each with its own area; name a room and pick its floor material in the panel. Add doors and windows from the palette — they snap onto walls and can open in 3D. Drag furniture in from the left, then switch to 3D view to walk through the plan.
Working in 3D
Use Orbit to look around from above and Walk to move through the room at eye level. In orbit mode you can drag furniture to reposition it and click a door to open it.
Reading the numbers
The panel shows the floor area, wall area, volume and perimeter as you edit. These are planning figures only, so measure the real room before buying materials.
