23'x49' Modern A-Frame House Plan 3 Bed 2 Bath 1,447 Sq Ft

This 23'x49' modern A-frame house plan delivers 1,568 sq ft of conditioned living space across two stories, with 3 bedrooms, 2 full bathrooms, and a dramatic floor-to-ceiling glass front wall set beneath a 21'10" gable peak. The steep A-frame silhouette does double duty here, shedding snow and rain while turning the roof itself into the primary structure, so you get real architectural presence on a narrow, buildable footprint.

Inside, the ground floor covers 1,127 sq ft and opens with a combined kitchen and dining area measuring 9'1" x 14'9", flowing directly into a living room of 9'1" x 12'11" that sits against the glass wall. Two bedrooms of equal size, each 10'4" x 10'5", share the rear of the plan alongside a full bathroom at 8'8" x 7'0" and a dedicated laundry closet with washer and dryer. A spiral staircase rises from the living room, saving the floor area a conventional stair would consume, and lands in a 441 sq ft second floor. Up there you get a private bedroom and sitting suite at 9'7" x 18'8", a second full bathroom at 8'10" x 7'0", a walk-in closet at 9'7" x 6'1", and an elevated porch of 9'7" x 7'1" tucked into the roof slope with clerestory glazing above it at 18'5".

Structurally, the plan sits on a drilled concrete pier foundation using 10" diameter piers set 60" deep on 24" thick post footings with no. 4 and no. 5 rebar, which makes it well suited to sloped, wooded, or raised lots where a slab would mean heavy excavation. The floor system uses 2x10 joists over treated sill plates and posts with 3/4" subfloor. Walls are 2x4 stud framing with housewrap, 7" plank siding, and detailed cedar tongue-and-groove rain screen assemblies. The roof runs 2x10 and 2x6 rafters on a 2x12 ridge board, finished in corrugated metal with cedar accents, and the drawings include five separate unvented attic insulation assemblies so you can match the assembly to your climate zone.

The plan fits owner-builders who want a weekend cabin they can actually finish, investors building a short-term rental where the A-frame shape itself is the marketing, families looking for a lake or mountain retreat with enough bedrooms for guests, and anyone who wants a compact full-time home with more character than a standard rectangle. The two-bedroom ground floor plus an upstairs suite also works well for multigenerational or shared-use setups.

Drawings follow 2022 California residential codes and are not sealed or engineered for other states. They do not meet earthquake seismic or hurricane wind code requirements, and many jurisdictions require a licensed engineer or architect to review and stamp plans before permitting. Confirm requirements with your local building department before you order and before you break ground.
