Nestled in the desirable Rosemont neighborhood, just steps from the Beaubien Cinema and Molson Park, LH4 is a unique residence designed by Shed Architecture. Transforming a duplex into a single-family home, it combines contemporary design, functionality, and exceptional brightness thanks to its four-story open staircase. Offering five bedrooms, three bathrooms, a powder room, and spacious living spaces, it captivates with its fluid layout, unobstructed views, and carefully selected materials. Its intimate courtyard, rooftop terrace, and solar panels make it a sustainable haven of peace.

Born from the complete transformation of a typical 1941 duplex, LH4 was built in 2015 under the vision of the firm la Shed, who transformed it into a contemporary and ambitious single-family residence. Ten years later, in 2025, la Shed and the designers at Vives St-Laurent are back for a refined update, faithful to the original spirit but resolutely focused on today's evolving lifestyles, aesthetic sensibilities, and functional needs.
The update includes a complete overhaul of the kitchen--the beating heart of the home--with improved organization, a dining area, a redesigned pantry, and new integrated appliances. Adjustments were also made to enhance privacy by adding partitions, soften contrasts in materials and harmonize colors, modernize the lighting, and renew the furniture in the common areas. The entire project was completed with an update of the textiles and accessories, and a reconstruction of the green rooftop terrace, ready to accommodate a spa.
A four-story, 4,250-square-foot house
LH4 stands out for its bright, fluid architecture, firmly anchored in its environment. The central staircase, a true signature of the Shed, connects the four levels, allowing light to circulate freely. The house has 17 rooms, including five bedrooms, three full bathrooms, a powder room, a spacious living room, a family room in the basement, and several optimized storage spaces.
On the ground floor, life is organized around the kitchen and its two central islands. A cozy dining room with a built-in fireplace and a bright living room with direct access to the backyard create a welcoming atmosphere. The second floor houses four bedrooms, including a master suite with a walk-in closet and en-suite bathroom, as well as a second family bathroom and a discreet laundry room. The third floor, bathed in light, opens onto two terraces: one with a view of Mount Royal, the other fully planted. It is a space for creativity, relaxation, or contemplation. The basement offers great versatility with a family room, a spare bedroom (or office), a bathroom, and ample storage space.
A commitment to sustainability and community life
LH4 combines design and ecology: a fiberglass green roof (50-year lifespan), solar panels covering up to 50% of electricity consumption, efficient heating (natural gas, forced air, radiant slabs, air exchanger with UVC purification), and parking with a charging station.
The intimate and verdant backyard extends the living spaces to the outdoors. In summer, the alleyway becomes a veritable meeting and play area, embodying the neighborhood's community spirit.
