Why whole-site pricing does not add up the way you would expect.
When a project involves more than one element — say a deck, some new paving and a planting refresh — it is tempting to price each piece separately and sum the total. In practice, a coordinated quote for the same scope is often meaningfully different from that sum, in both directions. Shared preliminaries (site access setup, a single skip or spoil run, one mobilisation of machinery) get spread across the whole job rather than charged per element, which tends to bring the combined total down relative to three separate small jobs. At the same time, sequencing constraints — earthworks and drainage have to happen before paving, which has to happen before planting — can add coordination cost that a single-element quote never has to account for.
This page sets out planning bands for whole-site landscaping work, the specific factors that move a quote within those bands, and two worked scenarios showing how scope changes the number. If you are pricing a single element — a retaining wall on its own, or just a new lawn — the dedicated cost page for that element will give a more precise range than this whole-site guide.
Cost drivers
What actually moves a whole-site number.
Scope and sequencing move a whole-site total more than any single finish choice — get these right before comparing quotes on materials.
Planning noteA quote that lists only new work, with no line for removal, disposal or access setup, is usually incomplete rather than genuinely cheaper.
Compare procurement approaches
One coordinated quote vs. staged, job-by-job pricing.
How you procure the work changes both the total price and how risk between stages is carried.

Worked scenarios
Two whole-site scopes and how they land.
The same rough site size can land at very different points in the range once the actual element list is fixed.
Flat 400m² suburban section, three elements
A new paved entertaining area of around 40m², boundary planting along two sides, and a replacement lawn. Access is good from the street, no retaining or significant earthworks are required, and the three elements are sequenced under one contractor: drainage checks first, then paving, then planting and turf last. This scope sits toward the lower half of the Typical band, closer to $40,000–$55,000, because access is straightforward and no structural element is involved.
Sloping 650m² section, five elements including retaining
The same property type but with a level change requiring a retaining wall to create usable flat area, a deck off the rear living space, new paving, planting and drainage rework — all coordinated under one sequence. Access is restricted to a single side gate, which slows every stage, and the retaining wall height means engineering input is required before pricing can be finalised. This scope sits in the upper Typical to lower Complex range, commonly $110,000–$160,000, driven primarily by the structural elements and restricted access rather than by finish choices.
Comparing quotes
What to check before comparing whole-site quotes.
Whole-site quotes are the easiest to misread, because two contractors can define "the same job" differently.
- Confirm every quote lists the identical element list — it is common for one quote to exclude something (fencing removal, an existing deck demolition) that another includes.
- Ask whether preliminaries (site setup, access, waste disposal) are itemised once for the whole job or embedded separately in each element's price.
- Check that the sequencing order is stated, particularly which trade goes first where earthworks, drainage and structural elements are all in scope.
- Get any structural element (retaining, deck footings) confirmed against an engineering assessment before treating that portion of the quote as final.
- Confirm what happens if ground conditions differ from what was assumed at quoting — ask how variations are priced, not just the base number.
Frequently asked questions.
Is it cheaper to landscape a whole site at once, or stage it over a few years?
Doing it as one coordinated project is usually cheaper in total, because preliminaries like site access setup and machinery mobilisation are shared across all the work rather than repeated at each stage. Staging can still make sense for cash flow reasons, but it is worth budgeting for the repeated setup cost that comes with it.
Why do two whole-site quotes for what looks like the same job come back so differently?
Almost always because the two contractors have scoped different things as included. Removal of existing structures, disposal fees, drainage provision and access setup are the most commonly inconsistent line items between quotes for the same visible brief.
Does landscaping a new-build section cost more or less than an established property?
It depends on what is already there. New-build sections often need more soil preparation and sometimes retaining or drainage work the builder has not addressed, but they avoid removal and disposal of existing structures, which can offset that cost on an established site.
How much of a whole-site budget should be set aside as contingency?
A common planning approach on sites with any earthworks, retaining or drainage uncertainty is to hold back a contingency in addition to the quoted price, since below-ground conditions are the most common source of variation once work starts.
