Toronto & GTA · Expert Craftsmanship
Built to Last
Backyard structures should feel like an extension of your home, not an afterthought.
In Toronto, that means building for real conditions: freeze-thaw cycles, moisture, shifting ground, and year-round use. At SZ Obsidian Builds, we approach every project from the ground up, with a focus on structure, durability, and long-term performance.

Serving Toronto & Greater Toronto Area
Premium Construction
A detached garage is one of the most valuable additions you can make to your property. It adds storage, protects vehicles, and increases resale value when built correctly.
We build garages that are square, level, and structurally sound from day one, not something that needs constant fixing.
Whether you need:
Single or Double Car
Storage-Focused
Fully Finished
Workspace Solutions
More homeowners are turning their backyard into functional workspace. But a backyard office needs more than four walls and a door.
Storage Solutions
A shed should solve problems, not create them.
Shift over time
Take on moisture
Fall apart quickly
Proper base and leveling
Framing that holds up structurally
Materials that handle Toronto weather
Clean, functional design
From simple storage sheds to fully customized builds, we match the structure to your needs.
Professional Spaces
If you need a dedicated space to build, work, or store equipment, a workshop needs to be built differently than a basic structure.
For equipment and heavy loads
Layout for your tools and workflow
Proper airflow for safety and comfort
Easy access and workflow design
“We build workshops that are practical, durable, and designed around how you actually use the space.”
