Free open-source traditional farmhouse blueprints — American Farmhouse, Extended, Southern and Backyard ADU cottages — with downloadable CAD files, detailed SketchUp construction models, PDF blueprints and renderings.
Why we recommend it
FreeFarmhouse is the rare open-source house plan you can actually build from. Not just PDFs: editable 2D CAD plus an unusually detailed SketchUp model (down to cabinets and floorboards) made in SketchUp + LayOut, designed to be copied, customized and improved under CC BY-SA — and people have built from it.
Strengths
- Truly free and open (CC BY-SA): CAD, SketchUp model, PDF blueprints and renderings downloadable at no cost
- Editable source files, not just prints — customize additions, porches, rear extensions yourself
- Construction-level SketchUp model showing how the house goes together, not a massing sketch
- Proven in the real world: American Farmhouse has been built (e.g. Virginia build documented on site)
- Range covers ~1,000 sq ft American Farmhouse plus 646/749/857 sq ft Backyard ADU cottages and a sub-500 sq ft Tiny option
Keep in mind
- Farmhouse vernacular only — a handful of related traditional designs, no modern, multi-family or commercial types
- Not permit-ready: no warranty, still needs local architect/engineer review for structure, code, energy and site compliance
- One-person project — site organization lags new designs, some newest files/updates funnel via Patreon/Instagram first
- US wood-frame assumptions throughout — detailing, dimensions and cost logic need adaptation elsewhere
