What you get

Numbers and drawings, not just a picture.

The builder prices what you actually drew. Framing, roofing, siding, and foundation quantities come off your dimensions with a 10 percent waste factor, so the estimate is a real starting budget before you order parts or call a builder.

  • A build cost that moves with the designSquare footage and estimated build cost tick in the corner while you drag. Widen a wall or switch to a standing-seam roof and the number follows.
  • A 6-page blueprint PDFDimensioned floor plan, four elevations, a wall-and-roof cross-section, and a foundation plan. Scale bar and title block on every page.
  • An itemized bill of materialsEvery line with a quantity, a unit, and a cost, grouped by foundation, framing, roofing, siding, and openings. Exports as CSV.

In the designer

Change anything, and watch the number move.

Tap a wall, a window, the roof, or the porch and edit it right where it stands. Sliders cover size, pitch, siding, roofing, foundation, colors, loft, and chimney. Nothing is locked behind a plan you have to start over from.

  • Tap a part of the cabin to edit that part
  • Drop to eye level and walk the clearing, on desktop or phone
  • Saves in this browser, and you can name and reopen designs
