This single-story plan holds 1,590 square feet of living space, with no garage, inside a simple 49'-3" × 34'-1" footprint. A plain rectangular shape keeps the exterior wall area low, which helps with insulation and air sealing. A front porch leads into a 14'-7" × 4'-5" foyer, which opens to the living room.
The living room (21'-5" × 15'-3"), dining area (9'-0" × 10'-11") and kitchen (12'-5" × 10'-11") sit together as one open space facing south. A pantry (8'-6" × 4'-9"), laundry (8'-10" × 5'-2") and mechanical room (8'-10" × 4'-2") are grouped nearby, so ducts and plumbing runs stay short. An 18'-6" hall leads to the bedrooms. Bedroom 2 (12'-3" × 8'-8"), Bedroom 3 (12'-3" × 9'-5") and the hall bath (8'-10" × 5'-10") are on one side. The primary suite (10'-9" × 13'-3") has a walk-in closet and a primary bath.

Who this plan suits
This plan suits a small family or couple who want three bedrooms, low upkeep and one-level living without a large footprint. It needs a lot about 50 feet wide or more, and the south side should face open sky so the living areas get winter sun.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story compact energy-efficient house, 3 bedrooms, 2 baths, simple footprint, open kitchen and living facing south, mechanical room, laundry, front porch, about 1,600 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 energy efficient house plans?
Energy efficient house plans use layout to reduce heating and cooling loads. Typical features are a compact footprint, living spaces oriented to the south and grouped service rooms. This plan applies those ideas in a single-story 1,590 sq ft layout.
What affects the cost and lot needs of this plan?
The footprint is 49'-3" × 34'-1", so the lot must fit that plus setbacks and the front porch. Cost depends on your region, foundation type, insulation level, windows and the mechanical system you choose. A local builder can price these once you have the plan set.
Can I change this plan by chat?
Yes. You can ask for changes in chat, such as resizing rooms, adding a garage on a chosen side or adjusting the plan for a narrower or wider lot. The layout is regenerated so the rooms still connect.
How do I use the PDF, DXF and IFC files?
The PDF is for review and sharing with a builder or lender. The DXF opens in CAD software for drafting and edits, and the IFC imports into BIM tools. Local code review and engineering are still needed before construction.
