Duplex Collection
Discover thoughtfully designed duplex floor plans that maximize space and privacy while offering the perfect balance of shared and independent living. These innovative two-unit homes feature separate entrances and complete living spaces under one roof, making them ideal for multi-generational families, rental income opportunities, or co-living arrangements.
Modern duplex designs seamlessly blend functionality with style, typically offering 2-3 bedrooms per unit, open-concept living areas, and dedicated parking. Each unit maintains its own kitchen, bathrooms, laundry facilities, and private outdoor spaces, ensuring comfortable, independent living. Common layouts include side-by-side units, stacked configurations, or front-to-back arrangements, each optimized for the lot size and privacy considerations.
Today's duplex plans incorporate contemporary features like first-floor primary suites, flexible home office spaces, and smart home technology pre-wiring. Energy-efficient designs include upgraded insulation, solar panel readiness, and modern HVAC zoning for individual climate control. Many plans feature spacious kitchens with islands, walk-in pantries, and connection to outdoor living spaces through sliding doors or covered patios.
These versatile homes excel at sound isolation between units, often utilizing advanced construction techniques and materials to ensure privacy. Thoughtful touches like separate utility meters, dedicated storage areas, and carefully planned parking solutions make daily living smooth and convenient. Whether you're looking to generate rental income, accommodate extended family, or share ownership costs with another household, duplex plans offer practical solutions with modern comfort.
Popular configurations range from 1,200 to 2,500 square feet per unit, with options for both single-story and two-story designs. Many plans feature adaptable spaces that can serve as home gyms, media rooms, or children's play areas. Exterior designs vary from traditional to contemporary, with options for mixed materials, varied roof lines, and architectural details that create distinct identities for each unit while maintaining a cohesive overall appearance.

Exterior Wall Construction Choices
Most of our stock plans come as 2x4 exterior wall construction by default. We do provide options to change the exterior wall type. Those options include 2x6 exterior walls, Post Frame Construction, CMU Block Construction, etc.
Foundation Types
When de signing our house plans, a default foundation is set for a given plan. If possible, we include options to change the foundation type to better match your construction needs. For instance, if the default foundation is an unfinished basement, you'll have the option to change the foundation type to a walkout foundation, crawlspace, or slab foundation.
Please note: Some of our plans are designed with special foundation needs, such as post and pier for waterfront properties. These plans may not allow an option to choose another foundation type. If you find yourself in need of an alternate foundation and aren't given the choice, please fill out the alteration request on the plan page.
Right Reading Reverse
One of our more popular options is reversing the plan. Ordering the reverse option will not only flip the plan on the sets for you, it will also correct the text to make the plan read correctly while reversed.
CAD Files
All of our plans are offered as digital PDF downloads. If you want to make changes to the plan yourself, there is an add-on option that will give you the CAD files. Our CAD files are exported in AutoCAD format. You must have software capable of opening CAD files to use them. This option is great if you are in the business of home building and need to make slight changes to the plans per lot.
