Open house plans: 503 concept floor plans as DXF, JSON and CSV

503 house plans, from 300 sq ft backyard units to large two-story homes: ranch, farmhouse, barndominium, cabin, craftsman, ADU, duplex and more. Each plan folder in plans/ holds

File	What it is
plan-level1.dxf (one per level)	The floor plan as a drawing. Opens in AutoCAD, BricsCAD, LibreCAD, QCAD and other CAD programs.
building.json	The same plan as data: the room program with an adjacency list, then rooms, walls, doors, windows and fixtures with coordinates in metres.
area-schedule.csv	Room schedule with sizes and areas.
thumb.jpg	Preview picture.
README.md	Summary, footprint, known issues, and links to the PDF plan set, the IFC model and the plan's page.

index.csv lists every plan with levels, footprint, area, tags, drawing units and the number of known issues, so you can filter before you download.

What these plans are, and what they are not

• They come from the plan engine behind AI Architectures (20Vision GmbH, Vienna). Each layout was generated with AI from a written brief and drawn by our own drafting code.
• They are concept designs. They are not construction or permit documents. Have a licensed architect or engineer check anything you intend to build.
• Our automatic checks found issues in many of them, such as a narrow room, an area that differs from the brief or a missing door. Each plan's README lists its issues, and index.csv counts them.

The collection in numbers

• 503 plans; 346 on one level, 157 on two or more.
• Indoor area including garages from about 310 to 4,821 sq ft; the middle plan has 1,875 sq ft.
• Drawing units of the DXF files: 375 in inches, 128 in millimetres.
• 96 plans have no issue found by the automatic checks; 407 have at least one, listed in their README.

Use

The files are free to download and to use for ideas, study and research, the same terms as on the site. If you share a plan or publish work that uses these files, please link to the plan's page or to this repository. For anything else, write to us through the support page.

Change a plan

Every plan's page has a tool that changes rooms, style or layout and exports the drawing again. The link is in each plan's README.

How this repository is made

build.py reads the library of the site, copies the public files and writes every README and index.csv. The two text blocks of this page are in _templates/.
