Plan
Floor plans with dimensions
Walls are cut at 1.3 m like a real plan, every room edge gets its dimension chain split at the doors and windows, and the measure tool snaps to corners and faces.

Draw the plan. Walk through the house.
Izbik is a 3D designer for flats and houses. Trace the walls over a scanned plan, add doors, stairs and roofs, furnish the rooms with furniture made to measure, then walk through them or send a link. An AI agent can do all of it with you.

Family house Žebětín: 3 floors, 41 walls, 4 roofs, 100 pieces of furniture. Modelled from its drawings by an AI agent in 17 minutes.
How it works
Draw the walls
Lay a scanned plan under the top view, calibrate it with one known length and click the walls along it. Rooms are found from the walls, with their areas.
Furnish it
Kitchens, wardrobes and shelves are sized by their parameters, so a cabinet fits the wall to the millimetre. Bought products come in as 3D models.
Show it
Walk through in first person, share a link with a client or a builder, print the plans, elevations and sections, or hand the joiner the cut list.
Features
One model, from the floor plan to the cut list
Everything is generated from parameters: change a wall and the plan, the 3D view, the drawings and the quantities follow.
3D
3D views and the walkthrough
Orbit the model, cut it at any height, or walk through in first person, opening doors as you go, with the keyboard or on a phone.
Houses
Floors, roofs, stairs and terrain
Stack floors on their slabs, climb them by stairs, cover them with gable, hip or flat roofs, and set the house on a sloping plot.
Furniture
Made to measure, with a cut list
Custom furniture is a definition of parts sized by expressions. Drawers open, doors swing, and the cut list gives every board with its edging.
Materials & light
Real finishes, sun and lamps
Tiles, planks and herringbone laid on the room's grid, the sun at any date and hour for your site, and lamps by their lumens and colour temperature.
Drawings
Plans, elevations, façades, sections
Print-ready PDF and SVG at architectural scales, with level marks and title blocks, plus a glTF of the model.
Quantities
Areas, quantities and cost
Room schedules, flooring, tiles and paint per room and material, and a cost estimate from your own prices.
Sharing
Share links and review comments
Send a link to a client: they walk through, switch the kitchen variant and pin comments to the spot they mean, without an account.
AI agents · MCP
Built by an AI agent, from the drawings alone
Izbik has an MCP server. Connect Claude or another agent, and it reads your scanned plan, draws the walls, places the doors and windows, furnishes the rooms and saves a version after each phase. Every change lands in the project's history, and you can undo it.

Run it on your own server
The whole app is on GitHub under the MIT licence. One Docker Compose stack, and your projects stay on your machine.
- The same app as izbik.com: editor, walkthrough, drawings, MCP server
- MariaDB and S3-compatible storage, MinIO included
- HTTPS with your own certificate, or behind your proxy
# Get the code and start the stack $ git clone https://github.com/marekskopal/izbik.git $ cd izbik && make up # Create the first admin account $ make admin # Open http://localhost:4400
Can I start from my existing floor plan?
Yes. Upload a scan or photo of the plan, calibrate it with one known length, and draw the walls over it. An AI agent can do the tracing for you.
Which AI agents work with Izbik?
Any client that speaks MCP with OAuth sign-in, such as Claude Code and Claude Desktop. The agent works as you and only in your projects.
Who owns my designs?
You do. Export them at any time, or keep everything on your own server with the self-hosted app.
Do I need to install anything?
No. Izbik runs in the browser, on a computer, tablet or phone. Installing it on your own server is optional.
What can I export?
Floor plans, electrical plans, wall elevations, façades and sections as PDF or SVG, room schedules, quantities, the cut list and the 3D model as glTF.
Start with the walls.
