A Smart Duplex Plan for Narrow Lot Infill

In the evolving landscape of urban infill and middle housing, few plans strike the balance between compact footprint and livable space like Job #22345 Duplex. This modern stacked duplex offers a strategic solution for developers, builders, and homeowners seeking density without sacrificing comfort or curb appeal

📐 Plan Overview

Dimensions: 25′ wide × 73′-6″ deep

Bedrooms: 6 total (3 per unit)

Bathrooms: 4 total (2 per unit)

Ideal For: Narrow lots with front-loaded access

🧠 Design Intelligence: Why This Plan Works

Stacked Layout = Smarter Land Use: The vertical stacking of two full units allows for increased density on narrow lots—perfect for urban infill or redevelopment zones. Each unit maintains privacy and autonomy, making it ideal for multi-generational living or rental flexibility

Open Concept Living: Both units feature open-plan living areas that maximize natural light and flow. The first-floor unit (1,125 sq. ft.) is optimized for accessibility and family-friendly living, while the second-floor unit (1,293 sq. ft.) adds a private balcony—an outdoor retreat that enhances livability

Modern Aesthetic with Market Appeal: The exterior boasts clean lines and contemporary styling, ensuring the duplex stands out in any neighborhood. This visual identity not only attracts buyers and renters but also aligns with city goals for modernized housing stock.

Garage Access Without Sacrificing Space: Each unit includes a one-car garage, a rare feature in narrow-lot duplexes. This adds value for homeowners and tenants while maintaining a compact footprint.

🛠️ Customization & Buildability

The plan is designed for flexibility. Modifications are welcome, and builders can adapt the design to local codes with the help of a licensed architect or engineer. The downloadable set includes CAD files and detailed PDFs—making it easy to integrate into your workflow
