Small Duplex House Plan | 790 Sq Ft | 2 Units, 1 Bed 1 Bath

This small duplex house plan provides 790 square feet of total heated living space across two independent units, each measuring 395 square feet. Designed for narrow or infill lots measuring 32 feet wide by 26 feet 8 inches deep, the plan maximizes land density while maintaining separate entrances and private living quarters. Each unit features a 1-bedroom, 1-bathroom configuration centered around a keeping room that serves as the primary social core.

Both units include a dedicated walk-in closet within the private bedroom, a feature often omitted in compact housing designs. The symmetrical arrangement simplifies plumbing and electrical runs, reducing construction complexity and long-term maintenance costs. A 6:12 roof pitch and 14-foot 2-inch maximum height allow the structure to integrate into existing neighborhood scales without visual obstruction.

Built on a slab foundation with 2x4 wall framing and 8-foot interior ceilings, this duplex prioritizes efficient construction methods that reduce material overhead. The straightforward geometry and compact footprint offer a clear path for builders focusing on cost-effective residential development. This design is well-suited for rental income, accessory housing, or multi-generational living scenarios where proximity is desired without sacrificing privacy.
