From site to construction documents, on one desktop.

One desktop

Every stage of a project opens on the same canvas. Canvases nest inside canvases, so a site, a building and its rooms stay linked, and a change in one is seen in the others.

Compact mode takes you through a task step by step. Canvas mode shows the whole picture, with every input and result you can trace.

The chain

  1. Site Boundaries, setbacks, context and maps.
  2. Feasibility Programme, areas and a first fee.
  3. Design Plans and options, tested against the brief.
  4. BIM Walls, rooms and types as linked records, with IFC exchange.
  5. Cost A rough order of magnitude and a pro forma, from the model.
  6. Construction documents Sheets and sets, issued from an accepted revision.

An assistant, labelled as AI

A built-in assistant answers questions about the platform and can fill in forms for you to check. Everything it suggests is marked as a proposal until you confirm it.

Proposal is how a suggestion is marked until you confirm it.

Questions

Is the demo free?

Yes. Nothing is charged, and no card is asked for.

Do I need an account?

No. You can start without one. Signing in with an email address keeps your demo work for 90 days instead of 7.

What happens to what I make in the demo?

It stays in your own demo space and is erased when it expires. Please do not upload confidential or client data.

Does the platform use AI?

Yes, and it is always labelled. The assistant runs on an open model, and its suggestions count only once you confirm them.

Can I exchange models with other software?

Yes. Models come in and go out as IFC, the open exchange format for buildings.
