A contemporary two-story semi-detached plan designed to maximize space
 

 
This contemporary two-story semi-detached plan features a symmetrical design combining two functional units within a building measuring 42 feet wide by 32 feet deep. With a total area of ​​2,688 sq. ft., two stories, and a finished basement, the model makes efficient use of its footprint while offering an interior layout suited to the needs of families and dual-unit residential projects.
 

 
The exterior architecture focuses on a clean, contemporary aesthetic. Dark horizontal siding, vertically proportioned windows, masonry elements, and wooden structures at the entrances create a balanced façade. The low-slope roof accentuates the building's horizontal lines and contributes to its modern character.
 

 
Two units arranged in a symmetrical layout
 

 
The ground floor is primarily dedicated to living areas. Each unit has its own independent entrance leading to the living room, dining room, and kitchen. The open-concept layout encourages natural flow between these three zones while minimizing partitions in the common area.
 

 
The kitchen features a central island that provides extra prep space and allows for integrated seating. A powder room and a separate laundry room complete this level. At the rear, a patio door opens onto an outdoor deck, creating a direct transition between the interior and the backyard.
 

 
An upper floor dedicated to bedrooms
 

 
Upstairs, the layout of each unit groups the more private areas together. This level includes several bedrooms and a full bathroom with a separate bathtub and shower. Storage spaces are also integrated into the design. This vertical separation between common areas and bedrooms is a key advantage of this contemporary two-story semi-detached design. Daily activities remain centered on the ground floor, while the upper level offers an environment better suited for rest and relaxation.
 

 
A finished basement for added versatility
 

 
The poured concrete foundation allows for a fully finished basement. Each unit includes an additional bedroom, an office, a living area, a kitchen, and a bathroom with a shower.
 

 
This layout offers a wide range of uses for the building. The lower-level rooms can accommodate needs such as remote work, a large family, or the creation of extra living space. Independent exterior staircases on each side further enhance the design's overall functionality.
 

 
Contemporary architecture without a garage
 

 
Omitting the garage allows for more living space while maintaining a total building width of just 42 feet. This feature is particularly appealing for urban and suburban lots where optimizing the building footprint is a priority.
 

 
The repetitive window placement and the symmetry of the two units create a cohesive architectural look. Clearly defined covered entrances ensure that each residence maintains its own private access.
 

 
A versatile and customizable semi-detached design
 

 
With its two stories, finished basement, open-concept living areas, and numerous rooms, this contemporary semi-detached plan serves as a highly versatile foundation for a two-unit residential project.
 

 
As with other Plan Maison Québec models, the layout can be adapted to suit specific lot characteristics, occupant needs, and project requirements. An architectural technologist can, for instance, work on the interior layout, openings, dimensions, or specific architectural elements to customize the plan.
