This cube house plan places a two-story, flat-roof volume on a nearly square 33'-6" × 33'-10" footprint. It has 1,700 sq ft of living space, not counting the carport. The ground floor opens from a 7'-10" × 7'-0" entry hall into a 14'-11" × 14'-11" living room. The 13'-11" × 7'-2" dining area and the 9'-0" × 9'-0" kitchen sit alongside it.
A study of 11'-11" × 7'-6", a guest WC and a 4'-6" × 9'-0" utility room complete the ground floor. The stair leads to a 14'-7" × 6'-10" landing hall that serves all four bedrooms and a shared bathroom. The primary bedroom measures 10'-8" × 14'-11" and has an 11'-3" × 6'-0" ensuite. The 17'-2" × 16'-6" covered carport shelters two cars, and its roof works as a terrace.

Who this plan suits
This plan suits families or work-from-home households who want four bedrooms and a study in a compact, square form. It needs a lot that can take a 33'-6" × 33'-10" footprint plus carport access at the front, with no basement excavation.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story modern house, 4 bedrooms, 2.5 baths, cube-shaped modern house with a flat roof, nearly square footprint: ground floor open kitchen, dining and living, study, guest WC, utility room; upstairs 4 bedrooms, bath and ensuite, covered carport for 2 cars at the front, about 150 m² (1,615 sq ft) of living space (garage not included). Metric European / Latin American layout: compact rooms, no basement.” An AI architect drafted the room program, a layout solver placed every wall and door, and the plan was checked automatically for room sizes, circulation and daylight. The same project produced the PDF sheets, layered DXF, IFC model and 3D model you can download above.
Frequently asked questions
What are cube house plans?
Cube house plans describe a compact, box-like home with a nearly square footprint, a flat roof and simple stacked floors. This version is two stories with 1,700 sq ft of living space, four bedrooms and 2.5 baths. The square form keeps circulation short and the envelope simple.
What affects the lot and building cost of this plan?
The footprint is 33'-6" × 33'-10", so the lot must fit that block plus the carport approach at the front. Cost drivers include the flat-roof waterproofing, the roof terrace over the carport, the number of wet rooms stacked around the stair, and local labor and materials. There is no basement, which avoids excavation costs.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing or swapping rooms, moving the carport to another side, or adapting the plan to a narrower or wider lot. The layout is then regenerated so the rooms still connect, and you can review the updated drawings.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plans with builders, designers or permit offices. The DXF opens in CAD software for editing and detailing. The IFC loads into BIM tools for coordination and model-based work. Local codes and engineering still need to be checked before construction.
