The Mulholland Legacy
Since 1968, the Mulholland name has stood for craftsmanship, integrity, and relationships that last. Founded by the late Jim Mulholland, the company was built on a foundation of quality that continues today through second-generation builder Ian Mulholland and third-generation builder Tanner Mulholland.
Working side by side, Ian and Tanner blend generations of hands-on experience with modern building science, thoughtful design, and transparent communication.

The Mulholland Difference
Satisfied Customers
“We recently had the pleasure of working with Tanner and his crew who did an outstanding job renovating our cottage. From start to finish, they were professional, knowledgeable, and meticulous in their work. They listened to our needs and concerns, providing valuable insights and suggestions on how to achieve the desired outcome. The finished result exceeded our expectations and we couldn’t be happier with the transformation. We would highly recommend Mulholland Construction Company to anyone in need of renovation work.”

“After bringing my Family to Canada from South Africa 32 years ago, it has been a real pleasure to work with pretty much the whole Mulholland family. From Ian’s mother Cathy, finding the Heritage Home we still live in to this day, to Ian and at times his Father Jim ,working over a period of time on pretty much every corner of this old girl. Ian did an addition with a family room, renovated our kitchen, and gutted the entire 2nd floor. He also constructed a new front porch and completed a major part of our landscaping. Ian was always working side by side with his team which kept things moving along as scheduled.”

"Mulholland Construction did an outstanding job on our cottage on Georgian Bay. From the beginning of the project, Tanner and his team were incredibly helpful, demonstrating professionalism and honesty every step of the way. They guided us through each decision with care and expertise, ensuring everything went smoothly. The in-house interior designer was a game changer, bringing our vision to life and making a significant difference in the overall outcome of our project. We can't say enough good things about this team. Highly recommend!"
