This modern cottage duplex plan features two symmetrical units, each offering approximately 1,231 sq ft of heated living space with 2 bedrooms and 1 bathroom. The design makes efficient use of space, combining simplicity with stylish dual-living functionality. 0
Exterior & Curb Appeal
The frontage of each unit measures roughly 28′ wide by 55′-8″ deep. 1 The paired layout creates a modern cottage aesthetic, with clean siding lines, compact roof pitch, and attached one-car garages (~258 sq ft each) that maintain the overall scale while providing practical vehicle storage. 2
Because the units mirror each other, the façade presents a balanced, cohesive appearance—ideal for dual-family living, rental investment, or multi-generational occupancy.
Interior Layout & Shared Flow
Each unit opens into an open-plan living/dining/kitchen zone, creating a combined space that supports both everyday family life and quieter evenings. With only one full bath per unit, the design emphasises compact efficiency rather than luxury scale.
From living space you’ll access the two bedrooms, typically located toward the rear for privacy and quiet. The attached garage enters via a mudroom or utility area, making transitions from car to home smoother.
Bedroom Layout & Privacy
- The primary bedroom in each unit is well-sized given the overall square footage and is placed away from the garage entry to reduce noise.
- The second bedroom provides flexible space—ideal for children, guests, or as a home office—while still sharing the central bathroom in a straightforward layout.
Additional Features
Ceiling heights of roughly 9′ are noted in the plan’s specification, helping the living areas feel open despite the modest footprint. 3 The exterior walls use standard 2×4 construction with the option to upgrade to 2×6 for enhanced insulation or performance. 4
Estimated U.S. Build Cost (USD)
Using a mid-range U.S. construction cost of approximately $170–$245 per sq ft, a rough estimate for a single unit (~1,231 sq ft) falls between **$209K and $301K USD**, excluding land, site work and other region-specific costs. For both units combined (~2,462 sq ft total heated), the total build cost could therefore range around **$418K to $602K USD**.
Pros & Considerations
- Pros: Efficient footprint with two full 2-bed units; mirrored design enables shared economies; attached garages add value; modern cottage styling appeals broadly.
- Considerations: With only one full bath per unit, the layout may feel limited for larger families or long-term multigenerational living; you’ll need a lot wide enough to accommodate the full duplex width plus setbacks; cost estimates exclude site and finish upgrades, which can add up.
