This single-story plan has a 39'-4" × 63'-0" footprint and 1,960 sq ft of living space, not counting the 13'-3" × 26'-5" two-car garage. You enter through an 8'-4" × 8'-4" foyer, with a guest WC and the laundry close by. The living room (23'-9" × 10'-11"), dining room (12'-3" × 10'-5") and island kitchen (17'-10" × 8'-2") form one open social zone. The gourmet balcony extends that zone outdoors.
The bedrooms are grouped around a 12'-1" × 15'-4" bedroom hall. Bedroom 2 measures 13'-3" × 9'-5", Bedroom 3 is 11'-3" × 9'-9", and Bedroom 4 is 13'-3" × 8'-6". A shared bath serves all three. The primary bedroom (12'-1" × 12'-11") has its own bath and an 11'-3" × 5'-9" dressing room. A 13'-3" × 6'-10" study gives you a quiet place to work.
Layout highlights
- Open living (23'-9" × 10'-11"), dining and 17'-10" × 8'-2" island kitchen share one social zone.

- Three more bedrooms open off a 12'-1" × 15'-4" hall, with a shared 11'-3" × 5'-2" bath.
- A 13'-3" × 6'-10" study sits apart from the bedrooms for work or homework.
- The 13'-3" × 26'-5" attached garage fits two cars, and the 5'-6" × 9'-0" laundry is near the foyer.

Who this plan suits
This plan suits families who want four bedrooms, a home office and a primary suite on one level with no stairs. The 39'-4" × 63'-0" footprint needs a lot wide enough for that width plus side setbacks, and deep enough for the full 63'-0" length.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story house, 4 bedrooms, 3 baths, primary suite with dressing room, open kitchen with island, dining, living, study, laundry, gourmet balcony, attached 2-car garage, about 180 m² (1,938 sq ft) of living space (garage not included). Metric European / Latin American layout: compact rooms, no basement; for a 15 x 30 m lot, so the building is at most 12.0 m wide (side setbacks) and about 23 m deep.” 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 house plans for a 15x30 lot?
They are floor plans sized to fit a lot of that width and depth after setbacks. This one is a single-story, 4-bedroom, 2.5-bath layout with a 39'-4" × 63'-0" footprint and 1,960 sq ft of living space. Check your local setback rules against that footprint before you commit.
What affects the cost and lot fit of this plan?
On one level, the roof and foundation cover the whole 39'-4" × 63'-0" footprint, so they account for much of the cost. The attached garage and the gourmet balcony add to the built area. Your local setbacks, soil and finish choices will matter more than the layout itself.
Can I change this plan by chat?
Yes. You can describe changes in plain language, such as resizing a bedroom, adding or removing the study, moving the garage to the other side, or narrowing the plan for a tighter lot. The layout is then regenerated, so the room sizes and square footage update.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the plan and sharing it with your family or contractor. The DXF opens in CAD software for drafting and measuring. The IFC loads into BIM tools for coordination. Have a licensed local professional review any file before you submit it for a permit.
