Luxury bi-generational house plan: the perfect combination of elegance, comfort, and independence
This luxury bi-generational house plan stands out for its modern architecture and impressive volumes, designed to provide a refined and functional living environment for two generations under one roof. Carefully designed by the technologists at Plan Maison Québec, this property offers a high-end living experience combining contemporary design, quality materials, and amenities tailored to family life.
Modern architecture and distinctive design
With its light-colored masonry facade accented with contrasting black elements, this modern bi-generational house is immediately captivating. The harmonious interplay of straight lines, large glass surfaces, and outdoor terraces creates an elegant and timeless aesthetic. Its flat roof and clean volumes perfectly illustrate the modern architectural spirit, while the large windows flood each room with natural light, accentuating the feeling of space and grandeur.
Separate yet connected living spaces
Designed to encourage harmonious coexistence between two households, this home offers two distinct units, each with its own living spaces. The ground floor features a spacious common area with a bright living room, a high-end kitchen, and a dining room opening onto the rear terrace. The fluidity of circulation and large openings provide unparalleled comfort on a daily basis.
The secondary unit, equally refined, allows another generation—parents, adult children, or relatives—to enjoy complete independence while remaining close by. This bi-generational concept meets today's needs: combining privacy, mutual support, and sharing, without compromising on comfort or aesthetics.
A spacious and well-designed interior
With a total surface area of over 8,000 sq ft spread over two floors, this luxury bi-generational home offers exceptional volumes. The 5 bedrooms and 4 bathrooms allow each occupant to enjoy their own private space. The mezzanine adds an extra dimension to the home, ideal for a relaxation area, an office, or a reading nook overlooking the ground floor.
Each level has been optimized to offer a fluid and functional living experience: a convertible basement, a spacious living room, a designer kitchen, a master suite with a double walk-in closet, and an en-suite spa-like bathroom. All these elements contribute to the cozy and prestigious atmosphere of this exceptional residence.
A triple garage and a fully finished basement
Practicality was not overlooked in the design of this luxury bi-generational house plan. The triple garage provides ample space for vehicles and storage, meeting the needs of large families or motorized recreation enthusiasts.
The finished basement perfectly completes this property, offering multifunctional spaces such as a family room, a gym, a home theater, or even a guest suite. This flexible layout allows the home to adapt to the evolving needs of its occupants.
