Marrying 1920s Heritage with Modern Structural Audacity
In the world of high-end residential renovation, there is a recurring nightmare: the “tacked-on” extension. You’ve seen it. A beautiful, soulful heritage home with a glass-and-steel box grafted onto the back like a poorly considered prosthetic. It’s the architectural equivalent of wearing a tuxedo with neon sneakers.
At J. Collins Construction, we prefer a more symphonic approach. Our latest project, Oxford, represents the successful marriage of a turn-of-the-century brick home with a sophisticated, light-filled modern extension. Realized in collaboration with the visionary Kimberly Watt Design and Maurice Martel Architect, the project is a masterclass in balancing what was with what could be.
The Foundation: Respecting the 1920s
The original structure, a 1920s brick classic, possessed a gravity and charm that you simply cannot replicate with modern prefabricated materials. To maintain this soul, our masonry work had to be surgical. Matching century-old brickwork isn’t just about finding the right colour, it’s about understanding the mortar, the weathering, and the original mason’s handwriting. We ensured the transition between the old and the new was seamless, so the extension feels like an evolution rather than an intrusion.

The Engineering: The Invisible Heavy Lifting
While the visual result is one of airy elegance, the behind-the-walls reality was a complex puzzle of steel and wood construction. To achieve the expansive fenestration (marketing-speak for massive, beautiful windows) and the soaring cathedral ceiling, we had to engineer a structure capable of withstanding Montreal’s snow loads without bulky, intrusive support columns.
We essentially built a high-performance skeleton to house a delicate heart. This included a total overhaul of the infrastructure—plumbing, electrical, and high-efficiency heating/cooling systems—ensuring this heritage home performs with the reliability of a 2024 build.
The Details: Where Luxury Lives
If the structure is the bones, the finishes are the skin. One of the standout features of Oxford is the flooring. We installed heated floors beneath engineered wood that was custom-made to match the grain and width of the home’s original 1920s floors. To ensure an exact match, the wood was stained and finished on-site. It’s the kind of detail that most people won’t notice immediately, but it’s the reason the room feels right.
From the intricate wall appliques to the carefully curated textures, every inch of the interior was designed to elevate the residential experience into a refined retreat.

The Question on Your Mind: “Does all that glass make the house cold?”
It’s the most common concern we hear: “I love the look of a cathedral ceiling and floor-to-ceiling windows, but will I be wearing a parka in my kitchen in January?”
The answer is a resounding no. Provided the engineering is sound. By using high-performance thermal-break glazing and integrating radiant heating beneath those custom-matched wood floors, we created a thermal envelope that stays cozy even when Montreal’s winter is at its worst. You get the view of the snow without its chill.

Expert Recommendation
If you are considering a heritage renovation, I highly recommend reading The Architecture of Happiness by Alain de Botton. He explores how the spaces we inhabit influence our moods and well-being. The Oxford project is a living embodiment of his philosophy: that a home should be a physical manifestation of our best selves.

Architecture is a visual medium. Reading about it is one thing. Seeing the light hit that cathedral ceiling is another. Click here to view the full Oxford Portfolio Gallery to see the interplay of textures and the scale of the masonry work for yourself.
What’s Next?
A project like Oxford doesn’t just happen; it requires navigating the complex world of municipal heritage permits. In an upcoming post, we’ll break down “The Heritage Hurdle: How to get your dream extension approved by the city without losing your mind.” Understanding these constraints early is the first step toward reaching your own residential goals.
