This modern duplex house plan offers a highly efficient and thoughtfully balanced multi-family design that combines contemporary simplicity with practical everyday living. Featuring a total of 1,384 square feet of heated living space, the structure is divided into two equal residential units, each providing 692 square feet of well-organized single-level living. Designed for flexibility, comfort, and efficient use of space, the duplex is ideal for rental income opportunities, multigenerational households, first-time investors, or owner-occupied living arrangements.
The exterior design embraces clean modern lines while maintaining a welcoming residential character. Measuring 38 feet wide by 47 feet deep, the duplex presents a compact footprint that fits comfortably on smaller lots while still providing privacy and functional outdoor living for each household. The low-profile 4:12 roof pitch reinforces the home’s modern architectural aesthetic while contributing to a streamlined and efficient structural form.
Each unit is designed with an open-concept layout that maximizes usable space and creates a bright, connected living environment. Nine-foot ceilings throughout the main floor significantly enhance the sense of openness, allowing the interiors to feel larger and more inviting despite the efficient footprint. The result is a comfortable modern living experience that emphasizes simplicity, flexibility, and natural flow between spaces.
At the center of each unit, the keeping or family room serves as the primary gathering area for relaxation and daily activities. The open arrangement creates seamless connection between the living room and kitchen, encouraging interaction while supporting modern entertaining and family lifestyles.
The kitchens are thoughtfully planned to balance functionality with visual openness. A central kitchen island provides valuable prep space, casual seating opportunities, and an additional focal point within the home’s shared living areas. A dedicated wall pantry enhances storage capacity and organization, helping maximize efficiency within the compact footprint.
Each residence includes two bedrooms and two full bathrooms, creating a highly desirable layout rarely found in smaller duplex designs. The first-floor master suites provide privacy and convenience while incorporating walk-in closets and private bathrooms for enhanced comfort. Secondary bedrooms offer flexible accommodations for guests, children, roommates, or adaptable personal use.
One of the most practical features of the design is the inclusion of dedicated home office or study spaces within each unit. These flexible areas support remote work, academic needs, hobbies, or personal organization, making the duplex especially well suited for evolving modern lifestyles where multifunctional spaces are increasingly valuable.
Outdoor living is thoughtfully integrated into the design through both front and rear porch areas assigned to each unit. Every residence includes an 18-square-foot covered front porch that creates an inviting entrance experience while reinforcing the duplex’s residential character. At the rear, private 92-square-foot porches extend the living space outdoors and provide comfortable areas for relaxation, dining, or quiet enjoyment.
Built on a slab foundation with durable 2x4 wall framing, the duplex emphasizes straightforward construction methods and long-term maintenance efficiency. The modest building height of 15 feet 5 inches preserves the home’s approachable scale while complementing its clean modern profile.
Architecturally, this modern duplex successfully combines compact efficiency with livable comfort. The balanced unit arrangement, open-concept interiors, private bedroom suites, and integrated office spaces create a versatile multi-family design capable of adapting to a wide variety of residential needs.
Whether used as an income-generating investment property, a dual-family residence, or a flexible owner-occupied housing solution, this duplex house plan offers modern functionality, efficient design, and long-term practicality within an attractive contemporary architectural framework.

Choose a building foundation for your home. The foundation provides stability to a home's structure from the ground up.
Slab - This concrete foundation is reinforced with steel rods and suitable for flat ground.
Crawl Space - This foundation is raised off the ground with low walls resting on footings, providing space for wiring, plumbing, and storage.
Basement - This foundation is entirely or partially below ground and offers storage or living areas.
Walkout Basement - This foundation is typically suited for rear-sloping lots and provides storage or living areas. Walkout basements have doors that provide access to the outside.

All house plans sold by Archival Designs have been designed to comply with the International Residential Code (IRC) and to the local codes in the area where the designer resides or where the house was built.
All house plans are designed to meet or exceed the national building standards required by the International Residential Code (IRC). Due to differences in climate and geography throughout North America, every city, local municipality and county has unique building codes and regulations that must be followed to obtain a building permit. Prior to purchasing a set of house plans, we recommend that you meet with your local building officials in order to determine the building requirements for your area. It is the responsibility of the purchaser(s) and/or builder to ensure that the structure is constructed to meet the codes of their local area.
Important Note:
House plans do not come stamped or signed by an architect or engineer. Additionally, house plans typically will not include structural engineering notes/calculations. Please check with your local building officials to determine if a stamp is required. If required, the building department will only accept a stamp from a licensed professional in the state where the home will be built.
Depending on your city, county, and state building requirements, house plans may need to be reviewed by a local licensed architect or engineer for structural details and code standards before construction begins. This is particularly true in coastal areas and those facing seismic events, extreme winds, and heavy snow. If you are building in any of these areas, a licensed structural engineer will likely be needed to provide the necessary calculations and additional drawings. We authorize the use of our plans conditioned on your obligation and agreement to strictly comply with all local building codes, ordinances, regulations, and requirements, including permits and inspections at the time of and during construction. We recommend checking with your local building department for the most current requirements. The purchaser(s) and/or builder are responsible for additional expenses incurred through meeting municipality requirements or other requirements for construction.
Our foundation plans have been designed for universal conditions and may need to be adjusted to fit your specific site conditions. The foundation should be modified by a local structural engineer to comply with soil testing laboratory findings and local building requirements.
Our house plans will include schematic electrical drawings; however, circuiting or wire sizing will not be included. Your electrical subcontractor will typically provide these drawings.
HVAC and plumbing drawings are not included. Your mechanical and plumbing subcontractors will determine the best layout for your site. Local HVAC codes, climatic requirements and commonly used systems vary throughout the country. The direction of how water flow will enter the home vary from case to case. For this reason, it is impossible to provide universal plans.
