32'x25' Modern Cottage House Plan 2 Bed 1 Bath, 800 sq ft

This 32'x25' modern cottage house plan delivers 800 sq ft of single-level living in a compact, efficient footprint built around an open kitchen and living core. The design pairs a clean hip roof with lap and cedar rain-screen siding, giving it a contemporary exterior that still reads warm and residential. Two real bedrooms, a full bath, dedicated laundry space, and a large deck make this one of the most practical small home layouts you can build without stairs, wasted hallways, or a complicated roof structure.

Inside, the kitchen measures 13'0" x 11'0" and includes room for a dining table alongside the range, sink, and refrigerator run. It opens directly into the living room at 10'7" x 13'2", so the shared space feels wide and connected rather than chopped into small rooms. Bedroom 1 is 12'4" x 11'0" with its own closet, and Bedroom 2 is slightly larger at 12'4" x 12'9", also with a closet, which makes the second bedroom equally usable as a primary suite, a nursery, or a home office. The full bathroom sits at 5'0" x 6'10" with a tub, toilet, and vanity, positioned centrally between the living area and the bedrooms. A washer and dryer area and a linen closet round out the interior storage. The deck wraps the entry with stairs and railing, adding usable outdoor square footage without adding to your heated area.

Construction follows straightforward, builder-friendly methods. The house sits on a concrete foundation wall with concrete footings on undisturbed soil, perimeter drainage, damp proofing, and an under-slab vapor barrier, with 2" board insulation at the foundation. Walls are 2x4 stud framing on 2x6 treated sill plates with headers sized from 2x6 up to 2x10. Floor framing uses 2x10 joists, and the hip roof is framed with 2x10 and 2x6 rafters, a 2x12 ridge board, rafter blocking, and 5-1/2"x8" roof beams. Overall building height is 19 ft 9 in, with the seal level at 12 ft and window openings at 9 ft, giving generous interior ceiling volume. Five different unvented attic insulation assemblies are detailed so you can match the approach to your climate zone.

This plan suits backyard ADUs and accessory dwellings, guest houses, short-term rental cottages, and downsizers who want everything on one level with no interior stairs. It also works well as a first build for owner-builders, since the rectangular footprint, simple roof, and complete material list keep the framing sequence and pricing predictable.

Plans are drawn to California residential codes and are not sealed or engineered for other states. They do not meet earthquake seismic or high-wind code requirements. Local building codes, zoning rules, and foundation standards vary, so have a licensed engineer in your area review and stamp the drawings before construction and confirm requirements with your building department.
