Interlocking and Landscaping: How to Plan a Combined Backyard Project

Most backyard transformations aren't one project — they're two. Interlocking and landscaping cover different halves of the same yard: the hardscape (patio, walkway, retaining wall) and the softscape (lawn, beds, plantings). Plan them as one combined project and each half makes the other better; plan them separately, in the wrong order, and you'll watch a machine drive across your month-old sod to reach the patio dig. Here's how to sequence a combined project so nothing gets built twice.

The iron rule: hardscape first, softscape second

Interlocking is construction. It involves excavation, tonnes of granular base material, compaction equipment, and cut-offs and gravel moving through your yard for days. Every bit of that traffic is fatal to new lawns and freshly planted beds — so the pavers, walls, and steps always go in first, and the living things go in around the finished structure. The bonus is precision: once the patio edge exists, sod meets it in a crisp line and beds wrap it exactly, instead of everyone guessing where the hardscape will eventually land.

Hardscape is the skeleton, softscape is the skin — and nobody puts the skin on first.

The planning sequence

1. Design the whole yard on paper first, even if you build in phases. Where do you sit, walk, play, and store things? The layout drives everything downstream.
2. Settle drainage and grading before anything is built. Water has to go somewhere — away from the house, not into the neighbour's yard. This is also the moment to consider permeable pavers, which let stormwater soak through instead of running off; Toronto's regional conservation authority (TRCA) promotes exactly this kind of low-impact design for good reason.
3. Build the hardscape: excavation, compacted granular base, pavers, walls, steps. In our freeze-thaw climate the base is the whole ballgame — it's why patios stay flat or don't.
4. Amend and grade the soil the construction phase disturbed. Post-construction ground is compacted ground; sod and gardens planted straight into it struggle.
5. Install the softscape: fresh sod against the new edges, then beds, shrubs, and trees.
6. Finish with mulch, lighting, and the details — the cheap layer that makes the expensive layers look intentional.

The sequencing mistakes we get called to fix

• Sod first, patio second: the classic. The excavator arrives in June and the month-old lawn leaves in wheelbarrows. Softscape always waits.
• No staging plan: pallets of pavers and tonnes of gravel need somewhere to sit — decide up front whether that's the driveway or the future lawn area, because whatever they sit on is getting redone.
• Grading each phase separately: the patio contractor grades for the patio, the sod crew grades for the lawn, and the seam between them ponds every time it rains. One grading plan, set before anything is built.
• Forgetting the underground layer: irrigation lines, landscape lighting wire, and downspout extensions cost little to trench while the yard is torn up, and a fortune to retrofit under finished pavers.

Budgeting a combined project

Rough GTA proportions: hardscape is the expensive half — interlocking commonly runs in the tens of dollars per square foot installed, driven by excavation and base work — while sod and garden beds cost a fraction of that per square foot. That asymmetry is useful: getting the hardscape footprint right matters enormously, while softscape can flex to fit the remaining budget, and can even be phased into next season without redoing anything, as long as the design was drawn as one. One crew handling both halves also means one accountable schedule and no finger-pointing at the seam between trades — the same argument we make for design-build gardens.

Where to start

Timing-wise, combined projects fit best in two windows: start hardscape in spring and the sod and gardens follow in early summer, or build hardscape in late summer and plant into September's ideal establishment weather. Either way, the design conversation should happen a season ahead — good hardscape crews book out, and rushing the sequence is how yards get built twice.

Start with the design conversation, not the paver catalogue. Our interlocking Toronto service handles the full hardscape side — patios, walkways, driveways, and retaining walls engineered for Ontario winters — and because we also do sod installation and garden planting, the whole sequence above happens under one roof, in the right order, with one quote.
