About
Building with Intention

Jamie Koffler, Founder & Principal
KDB Group was founded on a simple principle: that the process of building a home should be as considered as the home itself.
Jamie Koffler established KDB Group to bridge the gap between design vision and construction reality. With a background spanning both disciplines, Jamie brings a rare fluency — understanding not just what makes a space beautiful, but what makes it buildable, lasting, and true to its intention.
Every KDB Group project begins with listening. We work closely with homeowners and their design teams to understand not just the brief, but the sensibility — the way light should fall, the materials that should greet your hand, the details that make a house feel unmistakably yours.
Our work is concentrated in Toronto's most distinguished residential neighbourhoods, where we've earned a reputation for thoughtful execution, transparent communication, and a genuine care for craft. We're selective about the projects we take on because every home deserves our full attention.
What We Believe
Craft Over Convention
We don't follow formulas. Every project demands its own approach, informed by the home, the site, and the people who will live there.
Design Sensitivity
We understand design intent — not just the what, but the why. This fluency allows us to protect and elevate the architect's vision through construction.
Transparent Process
Clear communication, honest timelines, and no surprises. We believe the construction process should feel as considered as the finished home.
Material Integrity
We're particular about materials and the trades who install them. Quality is felt in the grain of the wood, the set of the stone, the silence of a closing door.
