Rendered in the builder

Dimensioned floor plan with porch, door swing, window openings, scale bar, and title block

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

Designing a cabin, answered.

Yes. The Off Grid Hubs cabin builder is free and runs entirely in your browser. No account, no signup, no CAD software. Pick a starter cabin, change anything you want, and export construction blueprints and a bill of materials.

Yes, and it updates while you work. The builder counts framing, roofing, siding, and foundation materials off your actual dimensions with a 10 percent waste factor, so the square footage and estimated build cost move the moment you widen a wall or switch to a metal roof.

Yes. Export a 6-page PDF with a dimensioned floor plan, four elevations (front, back, left, right), a wall-and-roof cross-section, and a foundation plan. Everything is dimensioned to the inch, with a scale bar and title block on every page.

Yes. The bill of materials lists every item with a quantity, a unit, and a cost, grouped by foundation, framing, roofing, siding, openings, and finishes. Export it as a CSV to price it out or hand it to a builder.

Yes. The free plan library has 20 cabins, from an 8x12 bunkie to a 24x30 barn house, and every one downloads as a 6-page PDF with a priced materials list. No signup. Open any of them in the builder to change it.
