Built on Craftsmanship. Driven by Detail.
Building Your Vision
Harrison Custom Contracting is a full-service residential construction company focused on high-quality custom builds and renovations. From year-round homes to seasonal cottages and waterfront structures, we approach every project with the same commitment to precision, durability, and design integrity.
We believe great construction starts long before the first shovel hits the ground. Our team works closely with homeowners, designers, and trades to ensure each build is carefully planned, transparently managed, and expertly executed — with no shortcuts and no surprises.
Whether you’re building from scratch, transforming an existing home, or adding a statement outdoor structure, our goal is simple: deliver spaces that feel intentional, functional, and built to stand the test of time.
CustOM Homes
From concept to completion, we build fully custom homes tailored to your lifestyle, land, and long-term vision. Every detail is thoughtfully designed and expertly executed, with a focus on craftsmanship, quality materials, and timeless results.
Luxury Garages
More than storage, our detached garages are designed as premium, multi-use spaces. From high-end finishes to custom layouts—including golf simulators and entertainment zones—we create garages that match the luxury of the home itself.
Home Remodels
We transform existing spaces into beautifully functional homes. From luxury kitchens and spa-like bathrooms to full basement renovations, our remodelling work blends smart design with precise construction to elevate how your home looks and lives.
Decks & Boathouses
We design and build custom decks and boathouses suited for waterfront living on Muskoka lakes and Lake Simcoe. Built to withstand the elements and complement their surroundings, our structures balance durability, beauty, and effortless outdoor enjoyment.

Garage Loft and Shed
What Our Clients Say
"My husband and I hired Harrison Custom Contracting to install 3 faucets and a water softener/filtration system for us. They did an amazing job, they were very professional and the price was right. So when it came time for us to grade/landscape our newly built property, it was an easy choice to use Harrison CC since we knew that it would be done right, quickly and for the right price. They exceeded our expectations and the quality of their work is impeccable. We plan on using them to finish our basement in the coming year, and I have no doubt it will be amazing!! I would highly recommend Harrison Custom Contracting!!"
Quality Work, Good Prices, Reasonable Timeline
What Our Clients Say
"When looking to do interior renovations on a rental property - I was searching for a local company with experience and previous work to look at. Harrison Custom Contracting was exactly that. With previous work shown to be more than what I was asking for, no job was too small. From demolition, to plumbing, to kitchen install & flooring and all other details, they did it all. They were efficient, easy to communicate with, and could answer any questions with recommendation. I would and will be recommending Ethan & HCC to anyone looking to have renovations or builds completed. These guys really do it all. Thanks again boys."
Home Renovation
What Our Clients Say
"If you are looking for a very personable, efficient and effective contracting firm, then choose Harrison Custom Contracting. Ethan positively contributed to our recent renovation of a 27 year old Lakehouse. He made constructive recommendations that enhanced the overhaul project tremendously. Most people cringe at the thought of doing a complete Reno but working with Ethan actually made this project fun. Yes fun. Ethan made communication with us a priority. Because we did not live near the project site, Ethan FaceTimed regularly and sent photo updates. We are so pleased with the finished project and would work with Ethan and his team again."
