GTA design-build · since 2016
GTA landscaping,
engineered to last.
Alterra designs and builds patios, interlock driveways, retaining walls, pools, and full backyards across the Greater Toronto Area — set properly the first time, and backed by a workmanship warranty.
WSIB-registered crews
HomeStars Best of 2020What we build
Five trades, one crew, one plan.
From the base course to the last light fixture, every part of the yard is handled by the same team — so nothing falls through the gap between contractors.
Hardscaping
Interlock driveways, patios, retaining walls, natural stone, walkways, and outdoor kitchens — set to hold their line for decades.

Explore enhancementsHow we work
Every build starts as a survey.
We read the land before we touch it — grade, drainage, sightlines, how you'll actually use the space. Then we set true north and build to it. Four steps, no surprises.
- 01
Consultation
We walk the site with you, talk through goals and budget, and map what's possible before anything is promised.
- 02
Planning
You get a clear plan — materials, layout, and timeline — with 3D previews on large builds so there are no surprises.
- 03
Execution
The crew builds it with progress updates along the way, so you always know where the project stands.
- 04
Follow-Up
We do a final walkthrough, sort out any details, and stand behind the work with a 3+ year warranty.
Our signature
We orient every build to your land.
The compass rose we set into this driveway is the same idea behind every Alterra project: find true north for the space, then build to it — square, level, and made to last.
The work
Real GTA projects, start to finish.
In their words
Homeowners across the GTA, on the record.
Real projects, real GTA neighbours — Alterra's own customers, in their words.
Alex and his team built a new expanded patio with lighting. The team was efficient and friendly… They worked hard each day and completed the job quickly and well. We highly recommend Alex at Alterra and will most certainly use his company for future landscaping needs. 10/10
We had a great experience with Aleks and his team to build our backyard patio. They were punctual, professional and finished the project on time. The price is also very fair. Most importantly, the work is of high quality. No shortcuts were taken. We are so happy with the results.
We had our backyard fixed by them and I couldn't be happier with the design and cleanness of their work. Alex and his team are very professional, on time and helpful. I strongly recommend them.
Alterra built multiple retaining walls, interlocked my driveway, put fresh sod in my backyard (after leveling it), and built/repaired some fences. All of this work was done in less than 2 weeks. I would highly recommend this team for any small or big landscape project!
The company
Led by Alex, built by a crew that shows up.
Alterra started in 2016 as a small, close-knit team and stayed that way on purpose. You deal with the people doing the work — the same crew, not a call centre — and every project is registered with WSIB and backed by a 3+ year warranty.
