starter home plans — dimensioned floor plan

This single-story plan fits 1,230 sq ft of living space, not counting the garage, inside a simple rectangular footprint of 44'-11" × 34'-1". A front porch leads into the main living area, where the 25'-9" × 10'-11" living room runs alongside the 15'-8" × 7'-4" kitchen and the 9'-4" × 7'-4" dining area. The kitchen, dining and living spaces share one open zone, so cooking, eating and sitting happen in the same room.

A 22'-7" hall connects the bedrooms to the shared spaces. The primary bedroom, at 11'-3" × 12'-3", has its own 5'-6" × 8'-4" ensuite. Bedroom 2 measures 10'-9" × 8'-4" and Bedroom 3 measures 8'-4" × 12'-3". Both use the 5'-6" × 8'-4" hall bath. The 7'-4" × 7'-4" laundry and the attached 1-car garage (16'-10" × 11'-9") sit next to the living zone, which keeps daily errands short.

Who this plan suits

This plan suits first-time buyers, small households and anyone who wants three bedrooms without stairs or a large footprint. It needs a lot a little wider than 45 feet, with room for the front porch and garage access from the street.

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, simple rectangle, open kitchen and living, laundry, attached 1-car garage, front porch, about 1,200 sq ft of living space (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 starter home plans?

Starter home plans are compact, efficient layouts meant to keep construction and upkeep manageable. This one provides 1,230 sq ft of living space, 3 bedrooms and 2 baths on a single level, with a 1-car garage that is not counted in that figure.

What affects the lot and building cost of this plan?

The simple 44'-11" × 34'-1" rectangle is straightforward to frame and roof, which helps control cost. Final cost still depends on your site, foundation type, finishes, local labor and code requirements, so get local bids before you commit.

Can I change this plan by chat?

Yes. You can describe changes in chat, such as adding or resizing rooms, moving the garage to the other side, or fitting a narrower or wider lot. The layout is updated to match, and you can review the result before downloading.

How do I use the PDF, DXF and IFC files?

The PDF is for reviewing and sharing the plan with builders or family. The DXF opens in CAD software for drafting and editing, and the IFC imports into BIM tools. Your builder or local designer should verify the plan against local codes before construction.
