A modern and functional side-by-side duplex plan


The side-by-side duplex plan we present here stands out for its resolutely modern design, practical layout, and high rental potential. Ideal for families, multi-generational projects, or real estate investors, this model offers a perfect combination of comfort, privacy, and profitability.


Designed in a contemporary architectural style, this semi-detached duplex captivates at first glance with its clean lines, inverted sloping roofs, warm exterior materials, and numerous windows that allow natural light into each unit. The harmonious architecture maintains a residential feel while maximizing the use of space on the same lot.


Two distinct and independent units


Each unit in the side-by-side duplex plan is completely independent, with its own private entrance, ensuring maximum privacy for occupants. The building spans 68 feet wide and 24 feet deep, offering a balanced and thoughtful room layout.


The ground floor of each unit features a spacious open area incorporating the kitchen, dining room, and living room. The layout promotes conviviality and everyday comfort. A full bathroom, a conveniently located laundry room, and a walk-in closet at the entrance complete this level with practicality.


A bright upper floor with a mezzanine and comfortable bedrooms


Upstairs, the side-by-side duplex plan offers two spacious bedrooms per unit, perfect for a family with children or a couple needing an extra bedroom or home office. One of the key features of this model is undoubtedly the mezzanine, which overlooks the living room and creates a beautiful sense of spaciousness.


This mezzanine can be used as a reading area, relaxation area, or open office. It adds a unique architectural dimension and enhances the brightness throughout the unit. Each room on this floor is designed to offer comfort, tranquility, and functionality.


A building designed for performance and elegance


With a poured concrete foundation and no basement, this model is perfectly suited to flat lots or areas where soil conditions make excavation more complex. The two-story layout optimizes living space while maintaining a compact and economical design.


This side-by-side duplex plan meets modern construction standards for energy efficiency, thermal insulation, and building envelope quality. The choice of materials, window layout, and natural air circulation contribute to a healthy and pleasant living environment, both summer and winter.


An ideal solution for rentals or bi-generational housing


This side-by-side duplex plan is an excellent choice for an income-producing housing project. It allows for two separate rental incomes while maintaining a refined appearance, unlike traditional multi-family buildings. It is also ideal for intergenerational occupancy, offering proximity and independence between occupants.


Whether you're looking to live in one unit and rent out the other, to accommodate family members, or for a purely rental project, this model meets a wide variety of needs. Its intelligent design makes it a sure bet in a constantly evolving real estate market.


More than just a plan, this template can be adapted to your needs


With its modern look, efficient layout, open mezzanine, two well-designed floors, and four bedrooms evenly distributed across two units, this side-by-side duplex plan offered by Plan Maison Québec represents a great solution for all your residential construction projects.
