Ambiance McMullan is a Montreal-based design and craftsmanship company focused on improving how spaces look, feel, and function.

We specialize in carpentry, landscape and architectural lighting, along with select projects that complement and enhance the overall design of a property. From subtle permanent lighting that highlights a home’s architecture to seasonal and holiday installations that bring warmth and character. We often work on properties where multiple small improvements come together to make a meaningful difference.

The company was founded by Aidan McMullan, driven by an interest for creative hands-on work, problem-solving, and thoughtful design. What started as a passion helping friends and family, quickly evolved into a business centered on creativity, craftsmanship, and atmosphere. Every project is approached with the same mindset of understanding the space, how it’s used, and designing something that you can enjoy and make memories with.

Unlike large, volume-driven companies, we remains highly involved at every stage. We meet clients on site, walk the property together, discuss ideas openly, and design solutions that make sense for both the space and the people who live there. From design and installation to adjustments and long-term maintenance, we believe the details matter, because they do.

Being local to Montreal means we understand the climate, the architecture, and the expectations that come with quality work in this city. We build with durability in mind, choose materials carefully, and aim for installations that age well over time.

Whether you’re looking to enhance your home with lighting, carpentry, or a combination of services, our goal is to help you enhance your property by creating an ambiance that feels effortless, refined, and uniquely yours.
