Features

Everything you need. Nothing you don't.

Professional-grade tools with a learning curve of about five minutes.

✏️

Draw any room shape

Rectangle, square, triangle, circle, or fully custom freeform — drop wall vertices and build any floor plan imaginable.

🧱

Walls, windows & doors

Add interior walls with a click. Place windows and doors on any wall. Edit thickness, height, and swing direction in the sidebar.

🪑

Built-in cabinet library

Drag base units, wall units, islands, appliances, and sinks straight from the library. Items auto-snap flush to the nearest wall.

🎯

Millimetre-accurate dimensions

Every measurement is live. Surface-area labels update as you reshape. Dimension lines display wall-to-wall lengths automatically.

🏠

Real-time 3D solid view

Switch to 3D with one click and orbit around the room. See exactly how your layout will feel before you lift a single tool.

📤

Export & share

Download a high-resolution PDF to hand to a contractor, or export the plan as a JSON file to reload later on any device.

From blank canvas to finished plan in 3 steps

No tutorial needed — the interface is built for people who've never touched CAD software.

Choose rectangle, square, triangle, circle, or draw a custom outline. Enter your dimensions in millimetres and hit Start Designing.

2

Drag items from the library, draw interior walls, and drop windows and doors onto any wall. Everything snaps to a configurable grid.
