This 4 bedroom house plan has a 30'-2" × 21'-0" footprint and 1,270 sq ft of living space over two levels, with no garage and no basement. The entrance hall (5'-1" × 8'-4") leads past the stair (5'-1" × 10'-4") and a guest WC (3'-10" × 4'-1") to the living room, which measures 12'-5" × 14'-7".
The kitchen and dining area are each 10'-0" × 9'-4", and an 8'-2" × 4'-1" utility room completes the ground floor.

Who this plan suits
This plan suits families who want four bedrooms in a compact, metric-style layout without a garage or basement. It needs a lot that fits the 30'-2" × 21'-0" footprint plus the setbacks your local rules require.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story house, 4 bedrooms, 2 baths, ground floor open kitchen, dining, living, guest WC; upstairs 4 compact bedrooms, bath and shower room, about 115 m² (1,238 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 4 bedroom house plan of 115 m2?
It is a home with four bedrooms and about 115 m2 of living space. This version has 1,270 sq ft of measured living area over two stories, not counting a garage. Rooms are compact, with the shared living spaces on the ground floor and all four bedrooms upstairs.
What affects the lot and building cost of this plan?
The 30'-2" × 21'-0" footprint is small and suits a narrow or modest lot, but local setbacks, soil and foundation type still decide what fits. Cost depends mainly on your region, finishes, and the two-story structure with its stair and two wet rooms upstairs plus the guest WC and utility room below.
Can I change this plan by chat?
Yes. You can ask for changes such as different room sizes, a garage on a chosen side, or a narrower or wider lot, and the plan is regenerated to match. Describe what you want in plain language and review the updated layout.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the drawings with your family, builder or local authority. The DXF opens in CAD software for 2D editing, and the IFC loads into BIM tools for 3D coordination. Local permit rules and engineering checks still apply before construction.
