This two-story semi-detached plan has 1,520 sq ft of living space, excluding the garage, with four bedrooms and 2.5 baths. The party wall runs along one long side and has no windows. Daylight comes from the other faces, and a 15'-3" × 12'-7" one-car garage is attached on the open side.
On the ground floor, the entrance hall (5'-2" × 11'-11") leads to the stair, the guest WC and the main rooms. The kitchen (6'-0" × 14'-7"), dining room (8'-10" × 10'-0") and utility room (8'-10" × 4'-2") form the working side of the house. The living room (12'-3" × 15'-3") completes the day zone. Upstairs, an 18'-10" landing serves the primary bedroom and its ensuite, three further bedrooms and the family bath.

Who this plan suits
This plan suits families who want four bedrooms and a garage in a paired-house format, with a guest WC and utility room downstairs. It needs a lot where the house can sit against a neighboring party wall, with side access for the garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story semi-detached house 8 m wide plus an attached 1-car garage on the open side, party wall on the other long side (no windows there): ground floor kitchen, dining, living, guest WC, utility; upstairs 4 bedrooms, bath and ensuite, about 140 m² (1,505 sq ft), garage not included.” 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 semi detached house plans with garage?
They describe a house that shares one long wall with its neighbor and has an attached garage on the open side. This plan has 1,520 sq ft of living space over two levels, plus a 15'-3" × 12'-7" garage that is not counted in that figure.
What affects the lot and building cost of this plan?
The main factors are the 29'-6" × 29'-6" footprint, the shared party wall and the garage on the open side. Local soil, foundation type, finishes and the neighboring structure also change the final cost, so get a local estimate before building.
Can I change this plan by chat?
Yes. You can ask for changes such as room sizes, moving the garage to the other side, or fitting a narrower or wider lot. The layout is updated and the drawings are regenerated to match.
How do I use the PDF, DXF and IFC files?
The PDF is for reading and sharing the plans. The DXF opens in CAD software for editing or drafting, and the IFC loads into BIM tools for coordination. Local permit drawings may still need review by a licensed professional.
