Handcrafted Outdoor Structures In Southern Ontario
We build custom heavy timber pergolas, pavilions, and covered outdoor rooms using quality Douglas Fir timbers and proven craftsmanship.
Every structure is built with strength, durability, and long-term outdoor performance in mind — made to handle Ontario weather and look beautiful for years.
Built for Ontario Weather
Outdoor structures in Southern Ontario need to stand up to a lot — hot summers, heavy snow, rain, wind, and constant freeze-thaw cycles.
That’s why we build with strong Douglas Fir timbers and focus on proper design, solid joinery, and durable finishing. The result is a structure that feels substantial, looks timeless, and is built to last.
Why Douglas Fir?
Douglas Fir is one of the best choices for heavy timber outdoor construction.
It offers excellent strength, natural beauty, and long-term durability. Its rich grain, solid feel, and structural performance make it ideal for pergolas, pavilions, and covered outdoor spaces.
When properly stained and maintained, Douglas Fir ages beautifully and continues to perform well in demanding outdoor conditions.
Handcrafted In-House
Each structure is carefully built in-house with attention to detail from start to finish.
From timber selection and layout to cutting, fitting, staining, and installation, we take pride in doing the work properly. These are not lightweight backyard kits — they are substantial outdoor structures built with real craftsmanship.
