A Stunning Muskoka Boathouse on Fairyland Island

Project Spotlight:
A Stunning Muskoka Boathouse on Lake Rosseau

At Gonneau Building Group, we pride ourselves on being the Muskoka boathouse builder families trust for generations. Our latest completed project — a breathtaking boathouse on Fairyland Island in Muskoka's Lake Rosseau — is a showcase of custom waterfront construction and generational craftsmanship.

A Legacy Three Generations in the Making

This is not just another waterfront project — it’s part of a generations-long relationship. For three generations, this family has contracted the Gonneau family to build, renovate, and maintain their cherished island property.

During this most recent build, one of our trusted trade partners uncovered a remarkable piece of history: a wooden door frame with the carved signature of Irwin Gonneau — Grandfather of our president, Eric Gonneau — from nearly 70 years ago, when Irwin originally installed the door on the adjacent Bunkie.

A Vision Brought to Life

Our client envisioned a boathouse that was more than a place to store boats — it needed to be a luxury waterfront space for gathering, entertaining, and relaxing year-round.
We worked closely with them to bring that vision to life, blending heritage craftsmanship with modern design. This custom waterfront build now offers:

  • A custom kitchenette for easy meal prep and entertaining
  • A spacious dining area for gathering after a day on the water
  • A cozy lounge space perfect for enjoying the lake in any season
  • High-end finishes and durable materials designed for lake life practicality

Why This Project Stands Out

This Fairyland Island boathouse is more than a project — it’s a story. It’s proof that generational craftsmanship still has a place in modern construction.

From the first blueprint to the last detail, every step reflected our commitment to quality, durability, and timeless design. It’s a build that will be enjoyed for generations — just as it has been for the past three decades
