Good Steward Tools

Plan to 3D Walkthrough

Upload a builder's floor plan, or a straight-on photo of one, trace the walls yourself, and walk the house in the browser before it is built. Cedar Lane House, a two-storey sample, is ready to open. No account and no payment. The plan never leaves your device.

For illustration only. Always confirm dimensions, structure, and layout with your builder, architect, or the permit set. This is not for construction.

How to use it

  1. Upload the plan. Add a builder PDF or a straight-on photo. PDF pages render in the browser. Pick the page for this storey. The file stays on your device.
  2. Set the scale. Tap two points on a known dimension and type its length in feet and inches.
  3. Trace the storey. Draw walls from point to point. Ends snap to corners and to square angles. Place doors, windows, room names, and stairs. Add another storey with its own plan page.
  4. Watch it build. Traced lines glow, then the walls rise storey by storey, and the roof drops on.
  5. Walk through. Orbit the dollhouse, lift the roof, and walk room to room. On a phone, use the on-screen joystick. Download a snapshot or a project file.

What you are looking at

The sample is Cedar Lane House, an original two-storey sketch on this page: entry and stair, living room, kitchen, dining, powder room, and an upper hall with bedrooms and a bath. It is not a built house and not a drawing set. Your own trace replaces it when you upload a plan.

Walls, doors, and windows are the lines you place. The walk stops at walls and passes through doors. A stair run climbs to the next storey. Room names sit on the floors. Lift the roof in the dollhouse view to see every level.

Use the model to talk about layout, not to build from it. Ask who will field-measure the house, which walls are structural, and how a layout change is written up. Re-verify a contractor at WA L&I Verify. When you are ready to shortlist, start with the Board directories. Board #1: Pacific Pro Group.

Plan to 3D Walkthrough FAQ

Is this model for construction or permits?

No. It is an illustration so you can picture a layout. Always confirm dimensions, structure, and openings with your builder, architect, or the permit set. It is not a survey and not for construction.

Does my plan get uploaded to a server?

No. PDF pages and photos are read in your browser. The sketch is saved only in this browser unless you download a project file or copy a share link. A share link carries the walls, not the plan image.

What can I upload?

A PDF, or a JPG or PNG photo taken straight on to the sheet. Some phones can also open a HEIC photo. If this browser cannot read HEIC, export a JPG or PNG and upload that.

Can I show more than one storey?

Yes. Each storey has its own plan page, walls, doors, windows, and room names. A stair run on a lower storey climbs to the storey above in the walk.

Does this cost anything?

No. There is no account and no payment. It runs in the browser on this site.
