Interlocking & Landscaping in Scarborough

Scarborough landscapes come with drama the rest of Toronto envies: table lands running to the Bluffs’ edge, ravine lots along Highland Creek, and 60-foot frontages that give a designer room to compose. They also come with responsibility — erosion setbacks, conservation rules and slopes where amateur retaining work fails within a decade. We build exteriors engineered for this geography and finished for the way you entertain.

Our hardscape follows estate practice: excavated, geotextile-lined bases compacted in lifts; concrete-restrained edges; walls with drainage stone, filter fabric and weep paths designed in from the start. On grade-challenged lots — and Scarborough has many — we terrace with armour stone and engineered walls that turn slope into usable platforms instead of maintenance anxiety.

From an Agincourt double driveway to a Guildwood bluff-side terrace with glass rails, one team designs, permits and builds.

Why Scarborough yards deserve our crews

We are one of the few landscape builders comfortable inside TRCA-regulated land. Bluffs-crest terraces, Highland Creek slope stabilization, drainage that must not accelerate erosion — we design to conservation standards, prepare the permit applications and build to the stamped drawings. Near the water, that competence is the difference between a terrace and a liability.

Away from the crest, we bring the same engineering to everyday scopes: driveways that stay flat through freeze-thaw because the base was built honestly, walkway lighting on separate zones, and planting plans keyed to Scarborough’s exposed, lake-influenced microclimates — tougher conditions than downtown gardens ever face.

Slopes, trees and TRCA rules for Scarborough exteriors

Standard interlocking needs no building permit, but Scarborough’s geography triggers others: retaining walls over one metre require engineered permits; driveway widenings and curb cuts go through Toronto Transportation Services (three to six weeks); and private trees over 30 cm diameter are protected by City bylaw, with permits and replanting plans required to remove or injure them.

The big one is conservation. Properties within TRCA-regulated areas — the Bluffs crest through Guildwood and Scarborough Bluffs, the Highland Creek and Rouge corridors — need TRCA permits for grading, walls, pools and structures, typically four to eight weeks. Erosion-hazard setbacks from the bluff edge are non-negotiable; we design within them from the first concept.

Client Words — Scarborough

Everyone else refused to touch our slope near the Bluffs. They got the TRCA permit and built terraces our whole street comes to see.

Frequently Asked Questions

Driveways install at $18 to $30 per square foot — most Scarborough doubles run $12,000 to $28,000. Terraced backyard projects with retaining walls range $60,000 to $180,000 depending on slope and stone. Design fees credit toward construction.

Usually yes, within the erosion-hazard setback TRCA establishes for your lot. Regulated-area permits take four to eight weeks and govern grading, walls and structures. We handle the application and design inside the approved envelope — our crest-side projects have all passed first review.

Terracing with engineered walls converts slope into flat, usable rooms; costs scale with height and length, typically $85 to $150 per face foot for armour stone or CMU-clad systems. Walls over one metre need permits and engineering, which we include in the scope.

Non-regulated projects booked in winter typically break ground in April or May. TRCA-regulated scopes should design by January to hit spring — the conservation review consumes four to eight weeks. Construction itself runs two to eight weeks for most residential scopes.
