Homeowners planning a yard usually think in pictures, and the pictures contain both halves at once: stone, planting, lighting, furniture, all finished on the same afternoon.
Yards do not get built that way, and the order matters more than almost any other decision. Get the sequence wrong and you pay for parts of the job twice.
The two halves, defined
Hardscape is the built, non-living part of the yard. Patios, walkways, driveways, steps, retaining walls, edging, the pad under a fire feature, the platform under an outdoor kitchen. It is excavation and aggregate and stone, and it is essentially permanent.
Softscape is everything living, plus the soil that supports it. Lawn, trees, shrubs, perennials, beds, mulch, topsoil. It changes every year, it fills in, and it can be adjusted.
Underneath both sits the part that belongs to neither and governs both: grading and drainage. Where water goes. It is decided first, it is invisible when finished, and it is the reason projects fail. We cover the full scope of that work in what landscape construction actually includes.
Why hardscape goes first
Hardscape construction is a heavy operation. Excavators, aggregate deliveries, material staging, wheelbarrow routes across the lawn, cuts made with a saw that throws dust over everything nearby.
Run that through a finished planting bed and the bed is finished in a different sense. Run it over new sod and you get compaction that the grass never recovers from, which is a slower and more confusing failure because it looks fine for the first month.
The reverse order is easy. Planting into a completed hardscape layout is straightforward work, the bed lines are already defined by the stone, and nothing heavy has to cross anything delicate.
There is one honest exception: large-calliper trees sometimes have to go in while machine access still exists, because a mature tree cannot be carried through a finished side yard by hand. That is a planning decision made at design, not a reason to reverse the sequence.
Underground before anything
Whatever else phases, the buried work does not.
Lighting conduit, irrigation lines, gas runs to a fire feature or outdoor kitchen, drainage pipe and any electrical: all of it goes in while the ground is open. Adding a low-voltage lighting run after a patio is set means lifting the patio, and the labour to do that costs more than the lighting did.
This is the single most common regret we hear on second-phase projects. The stone is beautiful and there is nowhere to put a light.
How the money divides
On a first project, hardscape almost always takes the larger share, and there are three reasons.
It is expensive per square foot, because most of the cost is below the surface. A patio is roughly a third of its cost in visible stone and two thirds in excavation, disposal, aggregate and compaction. Our base depth guide explains why we go past the ICPI minimums on Ottawa clay, and why cutting that depth is the false economy that produces a rebuild in year three.
It is permanent, so mistakes are expensive. A shrub in the wrong place is a Saturday. A patio in the wrong place is a demolition.
And it is what makes the yard usable. Planting makes a yard beautiful; hardscape makes it a place you can stand, walk and put a table on.
Softscape, by contrast, is genuinely phaseable. Trees can go in this year and the perennial layer next, and the yard improves rather than looking unfinished, because plants are expected to fill in over time.
What softscape is doing that stone cannot
None of that means planting is decoration. It does specific work.
It manages water. Beds absorb and slow runoff that stone sheds; a yard that is entirely hardscape moves more water faster, and it has to go somewhere.
It moderates the space. A large paved area in full west sun is genuinely hot in July. Shade, even young shade, changes when that space is usable.
It screens. In Barrhaven, Kanata and Stittsville subdivisions where lot lines are close, planting is what makes a patio feel private, and it does it better than a fence because it does not draw attention to the boundary.
And it softens the geometry. Hardscape is straight lines and hard edges. Without planting against it, a well-built patio reads like a loading dock.
Choosing plants that survive here
Ottawa is Zone 5a on Natural Resources Canada’s plant hardiness map, and the tag on a plant at a big-box store is frequently written for a warmer market.
Exposure adjusts the number in both directions. A windswept, snow-scoured spot behaves colder than 5a. A sheltered south-facing foundation bed behaves warmer and will carry things that would not survive across the yard. Salt exposure near the road and driveway is its own constraint, which we cover in the front yard landscaping guide.
Timing matters for lawn. Sod establishes reliably from late April through early June and again from late August through October. Midsummer sod can work with aggressive watering, and most people overestimate how aggressive they will be.
Plants we install carry a one-year replacement warranty when the aftercare plan is followed. Our scope is design and construction rather than ongoing maintenance, so you get a written aftercare plan at handover.
Boulevard work is a special case
If your plan reaches the strip between the sidewalk and the curb, that is City right of way rather than your property.
Ottawa permits residents to garden there without a permit under the Use and Care of Roads By-law, with real limits: nothing above 1.0 metre, 0.75 metres inside a corner visibility triangle, no trees, no hard materials such as rocks or pavers, no irrigation, and no changing the slope.
That last pair rules out extending an interlock walkway or setting boulders out to the curb, which is a common and well-intentioned mistake.
A workable phasing plan
If the whole yard is not happening this year:
- Phase one: grade, drainage and everything buried. Including conduit and sleeves for things you are not building yet. This is the phase not to compromise.
- Phase two: hardscape. Surfaces, walls, steps, the structural side of any outdoor living features.
- Phase three: soil and structural planting. Real topsoil depth, trees, hedging, the bones.
- Phase four: the layers. Perennials, mulch, lighting fixtures on the conduit already in the ground.
Phases three and four can spread across several seasons cheerfully. One and two cannot be reordered without paying twice.
Planning yours
We do both halves, which means the sequencing is our problem rather than yours, and nobody is standing in your driveway arguing about who compacted what. Our hardscaping and landscaping pages set out the full scope, and the gallery shows both working together on real Ottawa lots.
