Named after Roy Kostuk’s first project, Mayfield Custom Homes has been creating a personalized home building experience for customers in core Toronto areas since 1988. Our work on custom builds, renovations and commercial construction has established Mayfield Custom Homes as a trusted, dependable and client-focused family business.

Roy works with his son, Matt, and his trusted trades to provide you a personalized and hands-on experience, ultimately transforming your dream into reality. From start to finish, Roy and Matt are personally involved in every project; overseeing the work, communicating with you and consulting with their trades, guaranteeing your building experience is a positive one.

What sets Mayfield Custom Homes apart is our approach. We value quality and attention to detail. As a family business, we understand the importance of a home, and thus every design and decision is made carefully. We build homes that we would be proud to have our own family live in.
