This two-story colonial plan provides 2,690 sq ft of living space, not counting the garage, on a footprint of 40'-8" × 47'-11". A front porch opens into an 8'-0" × 14'-8" center hall. The living room (12'-11" × 17'-10") sits on one side of the hall. The formal dining room (11'-9" × 13'-1") and the kitchen (13'-3" × 13'-1") sit on the other side.
The kitchen opens to a 25'-5" × 10'-0" family room, with a 5'-6" × 6'-10" pantry nearby. An 8'-0" × 12'-7" office and a powder room are on the main level. The 2-car garage (25'-5" × 14'-11") enters through a 9'-4" × 6'-10" mudroom. Upstairs, a 37'-2" hall connects four bedrooms, a hall bath, and a laundry room. The primary suite has a 11'-3" × 19'-7" bedroom, a 11'-3" × 7'-0" bath, and a walk-in closet.

Who this plan suits
This plan suits families who want a traditional symmetrical colonial with formal rooms, a working office, and all four bedrooms on one floor. It needs a lot that can fit the 40'-8" × 47'-11" footprint plus setbacks, with driveway access to the garage.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story colonial house, 4 bedrooms, 2.5 baths, center hall, formal dining, living, kitchen open to family room, office, powder room, mudroom; upstairs 4 bedrooms, attached 2-car garage, front porch, about 2,900 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 colonial house plans?
A 4 bedroom colonial plan is a two-story home with a center hall and formal rooms on either side, with the bedrooms upstairs. This version has 2,690 sq ft of living space, 2.5 baths, and a front porch.
What affects the cost of building this plan?
The main drivers are the 2,690 sq ft of living area, the two-story form, the attached 2-car garage, and the front porch. Local labor, finishes, site conditions, and foundation type also change the final cost, so get local bids.
Can I change this plan by chat?

How do I use the PDF, DXF, and IFC files?
The PDF is for review and sharing with builders or lenders. The DXF opens in CAD software for drafting and editing. The IFC imports into BIM tools for coordination. A local architect or engineer should review the plan before permitting.
