Builders and general contractors
Agree with the client on exactly what will be built or renovated, and turn the same project into sales material.
House design, in your browser
Draw the house. See it in 3D. Get everyone to agree.
Stalonis turns a floor plan into a 3D house in real time, so builders, architects and homeowners can decide together what will be built, before anything is built.
Opening gradually — access is currently on request.
One project, every view
Plan, 3D and photo render stay in sync
Move a wall on the plan and the 3D house, the surfaces and the documents follow. No export, no second tool.
What you get
Everything to design, present and file a house project

Realistic visuals
Photo renders with real materials and light, to present a project or sell it before it exists.

How it works
From first sketch to finished file
The same four steps guide every project in the app.

Site
Place the house on its plot: boundaries, access, slope and local rules.
File
Answer a few questions to know which permit file the project needs.
Export
Download plans, visuals and documents, or share the project online.
Built for the meeting
Decide together, in the room
Stalonis is fast enough to change the project while the client watches. Move a wall, swap a window, try another roof — and see the result in 3D before the meeting ends.
