Plan Specifications
About This Plan
A single-storey duplex under one hip roof, drawn as two mirrored units on a 106 by 54 foot footprint. Each side is a self-contained two bedroom, two bathroom home with its own attached garage, its own porch and its own laundry. The duplex house plans arrive as an instant PDF download.
Architectural Style
Duplex house plansWhy the mirroring mattersBoth units are identical in reverse, which is what keeps a duplex economical to build. Plumbing stacks meet at the party wall instead of running to opposite ends of the slab, the framing repeats, and your contractor builds the same unit twice rather than pricing two different jobs.
Living Space
How each unit worksKitchen, dining and living run together as one open space. The primary bedroom has an ensuite bathroom, and the second bathroom serves the other bedroom and any guests. Laundry sits inside each unit rather than in a shared room, which removes the most common source of friction between tenants.
