This duplex design delivers two mirrored living units under one roof — each unit offering about 852 sq ft of living space. Combined, the total heated area is around 1,704 sq ft. Each side includes 2 bedrooms and 1 full bathroom, making it an efficient, affordable option for rental income, extended-family living, or dual-household households. 0
Exterior & Curb Appeal — Simple, Balanced & Duplex-Friendly
The building measures approximately 82′ 8″ wide × 34′ deep, with a ridge height near 18′ 4″, giving it a modest footprint that fits well on standard residential lots. 0 The symmetrical layout and traditional ranch-style roofline keep the exterior clean and approachable — a duplex that blends easily into a neighborhood without feeling bulky or out of place. 1

Unit Layout — Compact, Functional & Easy to Live In
Each unit is organized to maximize comfort within a small footprint. From the entry, you step into an open living/dining/kitchen zone — an efficient, no-wasted-space layout that makes everyday living easy. 2 The two bedrooms sit side by side, sharing the single full bathroom — a layout that works well for couples, small families, roommates, or tenants. 3
Outdoor & Patio Option — Simple Evenings or Weekend Grilling
Behind each unit there’s a small rear “grilling patio,” allowing a bit of private outdoor space for each household. 4 This feature adds value by giving a cozy outdoor nook — handy for a small garden, morning coffee, or a grilling spot — even though the home footprint remains modest.

Estimated U.S. Build Cost (USD)
Assuming modest but quality construction at around $140–$180 per sq ft, building this duplex (about 1,704 sq ft) could cost roughly **$238,000–$307,000 USD**, excluding land, site prep, permits, utilities, and regional cost variations. This makes it an affordable entry-level duplex — ideal for investors or budget-conscious homeowners. 0
