Talk to us about building your cottage or boathouse dream

From the initial foundation to the final coat of paint, Shorline Construction is dedicated to building quality boathouses for the Muskoka Lakes. We take pride in our work and we believe the results speak for themselves.

“My wife and I used Shorline Construction Limited to build a boathouse at our first cottage and we were so pleased we hired them to build our new cottage and boathouse in Muskoka. Again we found them to be very professional, thoughtful and concerned about quality work and looking after details. They are now building cottages for our sons. We would highly recommend Shorline Construction to any one considering building in Muskoka.”

  • “We chose Grant initially because David had recommended him for the boathouse and then for the main house there was no question that we loved Grant’s respect for detail and time. The boathouse was finished on schedule and his finishing detail is fabulous. Grant promised a finish date for the main house and this was really an important part of why we chose Shorline for this project but also we truly love the fact that Grant and his crew put so much pride in their individual craftsmanship. Each and every member of the team, from stonework, carpentry, finishing details and paint put 100% into their aspect of the project, which of course produces a spectacular end result. I know that when this building is finished we will not be disappointed”
