This two-story farmhouse has 2,910 square feet of living space, not counting the garage, on a 48'-11" × 42'-8" footprint. The front porch opens to an 8'-10" × 7'-8" foyer with the stair beside it. The 8'-10" × 19'-6" kitchen connects to a 12'-3" × 9'-8" dining area and a 12'-3" × 25'-5" great room, so the main living spaces read as one open zone. A pantry, laundry and mudroom, each 5'-6" wide, handle daily service tasks next to the 19'-2" × 21'-2" two-car garage.

The primary suite stays on the ground floor: a 10'-1" × 19'-2" bedroom with an 8'-8" × 8'-2" closet and an 8'-8" × 10'-8" bath. Upstairs, a 16'-8" × 8'-10" hall leads to Bedroom 2 (8'-4" × 19'-6"), Bedroom 3 (16'-4" × 6'-8") and Bedroom 4 (16'-8" × 10'-4"). It also reaches a hall bath, Bath 3 and a 21'-2" × 19'-6" bonus room.

Who this plan suits

This plan suits families who want a main-level primary suite, three bedrooms upstairs and a separate bonus room for play, work or guests. It needs a lot that fits the 48'-11" × 42'-8" footprint plus setbacks, with room for a front porch and a garage approach.

How this plan was made

It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story farmhouse, 4 bedrooms, 3.5 baths, ground floor primary suite, open kitchen, dining, great room, mudroom, laundry; upstairs 3 bedrooms, 2 baths and a bonus room, attached 2-car garage, front porch, about 2,800 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 4 bedroom farmhouse plans?

They are farmhouse-style home designs with four bedrooms, usually with a front porch, a simple gabled form and an open kitchen and living area. This version has two stories, with the primary bedroom on the ground floor and three bedrooms upstairs.

What affects the lot and building cost of this plan?

The 48'-11" × 42'-8" footprint sets the minimum lot width and depth once setbacks are added. Cost is driven mainly by the 2,910 sq ft of living space, the two-story structure, the attached garage, the porch and local labor and material rates.

Can I change this plan by chat?

Yes. You can ask for changes such as moving the garage to the other side, resizing or relocating rooms, or adjusting the plan for a narrower lot. The layout is revised to keep the rooms connected, and you can review the result before you download.

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

The PDF is for reviewing and sharing the plan sheets with a builder or designer. The DXF opens in CAD software for editing the 2D drawings, and the IFC loads into BIM tools for a 3D model. Have a local professional check the plan against your site and code before construction.
