This single-story plan has a footprint of 42'-4" × 49'-10" and 1,570 sq ft of living space, with the garage counted separately.

Who this plan suits
This plan suits families or couples who want three bedrooms, two baths and no stairs, with the primary suite kept apart from the other bedrooms. It needs a lot that fits the 42'-4" × 49'-10" footprint plus setbacks, with level or gently sloping ground and no basement.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story house, 3 bedrooms, 2 baths, split bedrooms, open kitchen with island and pantry, dining, living, utility room, covered terrace, attached 2-car garage, about 145 m² (1,561 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 is a 3 bedroom house plan at 145 m2?
It is a home layout with three bedrooms and about 145 m2 of living area. This version measures 1,570 sq ft of living space on one level, with the garage not included. Rooms are compact, so the plan works without a basement or a second floor.
What affects the lot and building cost of this plan?
The 42'-4" × 49'-10" footprint sets the minimum lot size once local setbacks are added. Cost depends mainly on foundation type, roof structure, finishes, the covered terrace and the attached 2-car garage. Local labor and material prices vary, so get a quote from a builder in your area.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing rooms, moving the garage to the other side or fitting a narrower lot. The layout is then updated and the room sizes are recalculated.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plan, including room sizes and the overall layout. The DXF opens in CAD software for drafting and detailing. The IFC imports into BIM tools, so an architect or engineer can continue the design. Have a local professional check the plan against your building code before construction.
