This modern split level plan stacks three staggered levels on a footprint of 29'-6" × 34'-5", with 2,390 sq ft of living space excluding the garage. The entry foyer (10'-8" × 6'-2") sits on the lowest level beside the 2-car garage (27'-7" × 12'-7"), a family room (16'-6" × 11'-5"), a fourth bedroom (13'-5" × 7'-8"), a bath and a laundry room.
A stair links each level. The middle level holds the living room (10'-8" × 24'-5"), the dining room (10'-11" × 11'-3") and the kitchen (20'-2" × 7'-8"), with a powder room off the landing hall. Upstairs, the primary bedroom (16'-2" × 10'-8") has a walk-in closet and a bath, plus access to the primary roof terrace. Bedrooms 2 and 3 share a hall bath along the upper hall. A deck extends the living level outdoors.

Who this plan suits
This plan suits households that want four bedrooms and a separate family room without a wide footprint. It needs a sloped lot that can take three staggered levels, with room for a 29'-6" × 34'-5" footprint.
How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Modern split-level house for a sloped lot with a flat roof: main level open kitchen, dining and living with large glazing; upper half-level 3 bedrooms including a primary suite, 2 baths; lower half-level family room, 4th bedroom, bath, laundry and a 2-car garage, about 2,300 sq ft.” 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 split level house plans?
Modern split level house plans offset floors by half a level, so each zone is reached by a short stair run instead of one full flight. Here the garage, family room and fourth bedroom sit low, the open kitchen, dining and living area sits in the middle, and the three upper bedrooms sit above. The result suits a sloped lot and keeps living and sleeping areas apart.
What affects the lot and building cost for this plan?
The main drivers are the slope of the lot, the foundation and retaining work needed for three levels, and the flat roof with its primary roof terrace. The 29'-6" × 34'-5" footprint is compact, but the 2,390 sq ft of living space is spread over three levels. Local labor, finishes and soil conditions will move the final figure, so get a local builder's estimate.
Can I change this plan by chat?
Yes. You can ask for changes in chat, such as resizing or moving rooms, switching the garage to the other side, or adapting the plan to a narrower or wider lot. The layout is regenerated so the levels, stairs and room connections stay consistent. Review any change against your lot and local code before you build.
How do I use the PDF, DXF and IFC files?
The PDF is for reading and sharing the drawings with your builder, lender or permit office. The DXF opens in CAD software for 2D editing and measuring. The IFC is a BIM model that you can open in compatible viewers or modeling tools to check the three levels in 3D.
