This single-story plan holds 480 sq ft of living space within a 31'-6" × 17'-5" footprint, with no garage and no basement. The living room (12'-1" × 10'-10") and the kitchen (6'-8" × 10'-10") share the same depth, so cooking and sitting areas work as one open room. A small terrace extends that room outdoors.
A compact hall (3'-7" × 6'-0") connects the open living area with the private rooms. The bedroom (9'-2" × 9'-0") is the single sleeping room, and the shower room (6'-0" × 6'-0") serves it and guests alike. A utility closet (4'-3" × 3'-5") adds storage for cleaning supplies and household equipment without taking space from the main rooms. Every room is compact, so circulation stays short and almost no floor area is spent on corridors.
Layout highlights
- Living room of 12'-1" × 10'-10" is the largest room and anchors the plan.
- Kitchen of 6'-8" × 10'-10" matches the living room depth for an open layout.
- Bedroom of 9'-2" × 9'-0" fits a bed, wardrobe and bedside storage.
- Shower room of 6'-0" × 6'-0" is entered from the 3'-7" × 6'-0" hall.
- Utility closet of 4'-3" × 3'-5" keeps storage out of the main rooms.

Who this plan suits
This plan suits a single person, a couple, or a guest house or rental unit that needs one bedroom and a simple open living area. It needs a lot at least wide enough for the 31'-6" × 17'-5" footprint plus local setbacks, with a flat or gently sloping site since there is no basement.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Single-story house, 1 bedroom, 1 bath, open kitchen and living, shower room, utility closet, small terrace, about 45 m² (484 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 1 bedroom house plan 45 m2?
It is a compact single-story home with one bedroom and about 45 m2 of living space. This version measures 480 sq ft excluding any garage, with an open kitchen and living room, a shower room, a utility closet and a small terrace.
What affects the lot and cost of building this plan?
The footprint is 31'-6" × 17'-5" on one level, so the lot must fit that size plus setbacks, and foundation work is limited to a single slab or similar base. Cost depends mainly on local labor, materials, foundation type, utility connections and the finishes you choose.
Can I change this plan by chat?
Yes. You can describe changes in chat, such as resizing rooms, adding a garage on a chosen side, or adapting the layout to a narrower or wider lot. The plan is regenerated so the rooms stay connected.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and printing the drawings and room sizes. The DXF opens in CAD software for editing plan lines, and the IFC imports into BIM tools for a 3D model. Have a local architect or engineer check the plan against your building code before construction.
