Who this plan suits
This plan suits families who want four bedrooms, a ground-floor study and a separate primary suite in a compact two-story volume. It needs a lot that fits the 45'-11" x 31'-6" footprint plus local setbacks and access to the 2-car garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story modern house, 4 bedrooms, 3 baths, flat roof, ground floor open kitchen with island, dining, living, study, guest WC, laundry; upstairs primary suite with dressing room, 3 bedrooms, bath, attached 2-car garage, about 190 m² (2,045 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 are modern 4 bedroom two story house plans?
They are plans that stack four bedrooms and the main living spaces over two levels, with clean lines and usually a flat or low-slope roof. This version puts the open living areas, study and garage on the ground floor and all four bedrooms upstairs, with 2,040 sq ft of living space.
What affects the lot and building cost of this plan?
The 45'-11" x 31'-6" footprint sets the minimum lot size once setbacks are added, and the 2-car garage needs a driveway approach. Cost depends mainly on local labor, structure, finishes and site work, so get a local quote before you commit.
Can I change this plan by chat?
Yes. You can ask for changes such as moving the garage to the other side, resizing or swapping rooms, or adapting the layout to a narrower or wider lot. The plan is regenerated with the new dimensions so the rooms still connect.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing the drawings and sharing them with your builder or designer. The DXF opens in CAD software for 2D editing, and the IFC loads into BIM tools for 3D coordination. Have a local engineer or architect check the plan against your local code before construction.
