Custom Garage & Composite Deck Built Around a Mature Maple Tree
When a homeowner in Guelph wanted a showpiece garage for woodworking and storage, LUMA faced three challenges: preserving a mature maple tree, managing water runoff from neighboring properties on a sloped lot, and creating a design that matched their existing home. The result: a custom timber frame and stone masonry garage with a Trex composite deck—built to last, designed to inspire.

What We Built



Custom Timber Framing
Hand-crafted fir timber framing designed to complement the home's existing architecture. Every beam was selected and positioned to create visual interest while respecting the mature maple tree's placement. The exposed timber details became one of the homeowner's favorite design elements—a signature of LUMA's commitment to craftsmanship.
Stone Masonry & Color-Matched Siding
The lower exterior features hand-placed stone masonry, while Gentex siding was color-matched to the existing home for seamless integration. This attention to detail ensures the garage doesn't stand out—it complements. The stonework also provides visual weight and durability, protecting the structure for decades.


Trex Composite Deck with TimberTech Railings
A low-maintenance Trex composite deck with black TimberTech Series railings wraps around the hot tub space. Unlike pressure-treated wood, composite won't rot, splinter, or require staining. Built to last 25+ years with minimal upkeep—perfect for families who want to enjoy their backyard, not maintain it.
Advanced Drainage System
The lot sits on a downhill slope with water runoff from neighboring properties. LUMA engineered a buried Big O drainage system with clean-out access around the back of the garage—diverting water away from the foundation rather than allowing it to accumulate. This proactive solution protects the structure long-term and was especially critical given the region's heavy rainfall patterns.

Designing Around What Matters:
The Mature Maple Tree
When the homeowner first approached LUMA, they had a clear vision: a custom garage that would serve as both storage and a dedicated woodworking workshop. But there was a catch—they wanted to preserve a mature maple tree that had stood in the backyard for years.
Most builders would simplify: remove the tree, build the garage, move on. LUMA saw it differently. The tree wasn't an obstacle—it was an opportunity to design something unique.
The team worked through multiple iterations to position the garage so the tree would remain the focal point of the backyard, with its canopy framing the structure perfectly. The doors were positioned for full access and operation, and the timber framing was scaled to complement—not compete with—the tree's natural presence.
But the tree challenge was just the beginning.
The Real Challenge: Site Drainage & Erosion Management
Once excavation began, LUMA discovered the real complexity of the site. The property sits at the bottom of a slope, with water runoff from neighboring homes flowing downhill. During heavy rainfall, water pooled against the foundation—a problem that would eventually lead to foundation damage, basement water intrusion, and costly repairs.
​
LUMA immediately pivoted. Instead of a simple build, the team engineered a comprehensive drainage solution: a buried Big O drainage system installed around the perimeter of the garage with accessible clean-out ports. This system intercepts water before it reaches the foundation, directing it safely away from the structure.
The homeowner later noted that this decision proved invaluable. After a year of heavy rainfall in the region, the garage remained bone dry—proof that LUMA's upfront engineering thinking prevented a future crisis.
​
This is the difference between building a structure and building a **home** that will stand the test of time.

How LUMA Designed This Project
Before a single nail was driven, LUMA created a detailed 3D render of the finished project. This isn't a luxury—it's standard on every LUMA project. The homeowner could walk through the design, make adjustments, and visualize the final result before breaking ground.
​
Why this matters:
Confidence:
You see exactly what you're building before committing.
Decisions made early:
Changes on a computer cost far less than changes on-site.
Clear communication:
The render becomes a shared reference between homeowner, builder, and trades.
​
The homeowner reflected on this: *"When Luma presented us with the 3D render, our final home looks exactly like it. They basically built exactly what they promised, and that's something I really appreciated."*
This is how LUMA operates on every project—transparent design, honest communication, and a commitment to delivering what was promised.
The Transformation: From Unused Space to Backyard Showpiece
Before:
An aging shed, an old pressure-treated deck, a mature tree, and a sloped lot prone to water pooling.
After:
A custom timber-frame garage with stone masonry, a low-maintenance composite deck, strategic drainage, and a backyard that finally feels finished.
The homeowner now has:
- Dedicated woodworking workshop and storage for tools, bikes, and seasonal items
- A space where grandkids feel welcomed and safe
- A backyard focal point that actually complements (not clashes with) the home's architecture
- Long-term protection against water damage and foundation issues
- A deck that requires virtually no maintenance—no staining, no pressure washing, no repairs
​
But here's what surprised them most: the craftsmanship details. The fir timber framing and the precision of the composite deck installation exceeded expectations. This wasn't just a functional garage—it was a showpiece.

"If a friend or anyone asked us who we'd recommend for any kind of custom build or custom project, we would say Luma Build Design hands down. They were honestly a pleasure to work with. They're super transparent and quick to respond. When Luma presented us with the 3D render, our final home looks exactly like it. They basically built exactly what they promised."

Building Custom Garages in Guelph:
What We Know
Guelph and the surrounding North Wellington region present unique building challenges: sloped lots, mature trees worth preserving, complex drainage patterns, and strict Eramosa Township permitting requirements.
​
This project is a case study in those realities. When we started, we weren't just building a garage—we were engineering a solution to a site that wanted to keep what mattered (the tree, the view, the landscape) while adding functional space that would last decades.
​
The drainage system we installed here is something we've refined over 20+ years in this region. We know how water moves through these properties. We know which townships require inspections at which stages. We know which materials and methods stand up to Ontario winters and heavy seasonal rainfall.
​
If you're in Guelph, Fergus, Elora, Elmira, or the surrounding Centre Wellington area and you're considering a custom garage, addition, renovation, or outdoor living space, you're working with a builder who understands your site's specific challenges—not a one-size-fits-all approach.
That's the LUMA difference.
Common Questions About This Project
How did LUMA preserve the mature maple tree while building the garage?
The team designed multiple iterations to position the garage in a way that kept the tree as the focal point of the backyard. The garage sits slightly offset, and the doors are positioned for full operation without interference from the tree's canopy. The timber framing and exterior design also complement the tree visually rather than compete with it. The result is a backyard where the tree feels integrated into the landscape design, not pushed aside.
Why is composite decking (Trex) worth the extra cost?
Pressure-treated wood typically lasts 10-15 years before requiring sealing, staining, or replacement. Composite decking (Trex) lasts 25+ years with virtually zero maintenance—no staining, no pressure washing, no rotting or splintering. Over the lifespan of a deck, the maintenance costs of wood often exceed the upfront cost difference of composite. For homeowners who want to enjoy their deck rather than maintain it, composite is a clear investment in both time and money.
