For detailed examples, see our backyard project price list or try our interlock cost calculator. Every backyard is built by a family-run interlocking contractor in Ottawa, not a subcontracted crew.
Our Ottawa crews design and build complete backyard interlock projects. We coordinate every element – patios, walks, walls, steps, planters, and lighting – so the finished backyard works as one outdoor living space. We handle grading, drainage, and lawn restoration so the result is ready to enjoy on day one.
Ottawa frost line is 4 feet. A 4-inch base lifts the second winter. Backyard patios get 8-10 inches of compacted base, walkways 6-8, driveways 10-12.
Same family-owned crew runs every project. Headcount stays at 11 so the lead installer is on-site 80% of every install.
Local crew that knows Ottawa soils, frost line, and municipal requirements. Quick callbacks if anything ever needs attention.
Same-day reply on phone and email every business day. The other 14 took 48.
Both certificates available before any project starts. No grey-market crews on your property.
Freeze-thaw rated for Ottawa winters. We do not install discount lines that fail year two.

I would definitely recommend this company, the entire planning process was great with awesome communication and the work ended up at a fairly reasonable price. If i ever need landscaping services again im coming back 100%
The new interlock completely changed the look of our place. Really pleased with the finished job.
The team was great and I would definitely hire them again. Thank you so much

Techo-Bloc, Permacon, Unilock, Belgard. Natural stone capping. Low-voltage lighting. Drainage gear sized for Ottawa rainfall. All picked during your on-site visit.
Kanata. Backyard transformations across Kanata Lakes, Bridlewood, Morgan’s Grant, Beaverbrook, and Katimavik. Typical Kanata builds: 400-600 sq ft patio + seat wall + steps – $11,000-$20,000 plus HST range.
Barrhaven. Backyard builds across Half Moon Bay, Stonebridge, Longfields, Davidson Heights, Chapman Mills, and Strandherd. Small Barrhaven lots need clever multi-purpose design – seat walls that double as planters, etc.
Orleans. Backyard work across Avalon, Fallingbrook, Chapel Hill, Convent Glen, and Queenswood Heights. Sloped Orleans yards often need multi-level patios with retaining walls, usually starting around $15,000 plus HST.
Nepean. Backyard transformations across Centrepointe, Tanglewood, Crestview, and Trend-Arlington. Mature Nepean yards mean tree-aware design and shade-friendly paver colours.
Stittsville. Large-lot backyard builds across Jackson Trails, Crossing Bridge Estates, and Amberwood. Stittsville supports full outdoor-living builds – outdoor kitchen, multi-level patio, integrated lighting – $40,000-$80,000+ range.
Gloucester. Backyard installs across Beacon Hill, Blackburn Hamlet, and Hunt Club. Gloucester slopes often need engineered retaining walls before the patio – we design and build both together.
Manotick. Estate-scale backyards across Mahogany, Manotick Estates, Long Island, and Manotick Village. Pool surrounds, outdoor kitchens, multi-level entertaining spaces – $35,000-$80,000+ typical, with outdoor kitchens quoted after the site visit.
Riverside South. Backyard builds across Honey Gables and the Riverside South village. New-build yards usually start as bare grass – we design from scratch with patio, walks, and planters.
Centretown. Tight courtyard backyards across the Golden Triangle and Centretown West. Small downtown spaces benefit from built-in seating, planters, and vertical garden walls.
Westboro. Heritage backyard installs across Westboro Beach, Highland Park, and McKellar Park. Older Westboro yards often have mature plantings worth preserving – we work around them with careful excavation.
Alta Vista. Backyard transformations across Heron Park, Faircrest Heights, and Playfair Park. Sloped Alta Vista yards usually need a retaining wall + patio combination – we design both as one project.
The Glebe. Heritage backyard builds across the Glebe and the Old Ottawa South border. Narrow lots, neighbour-adjacent fence lines, original heritage hardscape – careful design and access coordination.
