This two-story coastal plan has 1,860 square feet of living space on a compact 37'-5" × 32'-6" footprint. The ground floor holds the kitchen, dining room and living room in one open run. Entry is through the front porch into a 5'-5" × 11'-3" foyer, with the stair beside it and a powder room and pantry close to the kitchen.
The kitchen (11'-7" × 12'-11") sits between the pantry and the 10'-11" × 10'-11" dining room, and the 23'-5" × 12'-2" living room opens toward the rear porch. Upstairs, a 19'-11" × 6'-2" hall connects all three bedrooms, the hall bath and the laundry. The primary bedroom (17'-2" × 10'-4") has its own bath and a walk-in closet.

Who this plan suits
This plan suits families who want three bedrooms and a laundry on one floor, with the living spaces below and porch access at both front and rear. The 37'-5" × 32'-6" footprint fits a relatively narrow lot, and it has no garage, so parking would need to be planned separately.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Two-story coastal house, 3 bedrooms, 2.5 baths, ground floor open kitchen, dining, living, powder room; upstairs 3 bedrooms and laundry, wide porches, front porch, about 2,000 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 3 bedroom coastal house plans?
They are home layouts with three bedrooms and a coastal character, typically including porches, open living areas and a connection to outdoor space. This version has two stories, 2.5 baths and 1,860 square feet of living space, with porches at the front and rear.
What affects the cost and lot requirements of this plan?
The footprint is 37'-5" × 32'-6", so the lot must fit that plus the porches and local setbacks. Cost depends on your region, foundation type, finishes and any coastal or flood requirements, which should be checked with your local building department.
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 adjusting the plan for a narrower or wider lot. The layout is then regenerated so rooms stay connected.
How do I use the PDF, DXF and IFC files?
The PDF is for reviewing and sharing the plan. The DXF opens in CAD software for drafting and edits, and the IFC imports into BIM tools. A local designer or engineer should review the plan before permit submission.
