Check what's actually in the build contract before assuming landscaping is covered.
New-house build contracts vary widely in what landscaping scope, if any, is included. Some include a minimal allowance — basic grading and turf, perhaps — while others exclude landscaping, fencing and even driveway surfacing entirely, leaving the section as bare compacted clay at handover. Assuming a fuller scope is included than actually is, and only discovering the gap after settlement, is one of the most common budgeting mistakes new-house owners make.
The practical fix is to read the contract's landscaping-related clauses specifically and early, then treat any gap as its own budget line — reserved separately from the house build budget, planned in stages if needed, rather than squeezed in as an afterthought once the mortgage and moving costs are already committed.
01 · A staged approach to budgeting
Three budgeting bands, from minimum-viable to full brief.
Compliance minimum
Enough grading, ground cover and drainage to control mud and dust and meet any final inspection or bond-release condition — often the priority immediately at handover.
Functional baseline
Basic lawn, a practical path or access surface, and enough planting to stop the section looking unfinished — a reasonable first stage after settlement.
Full brief
The complete landscaping vision — hardscape, structures, a considered planting palette — usually planned and budgeted as a later, separate stage once the household understands how the site is actually used.
Contingency
New-build sections often reveal surprises once ground is opened up — compacted subsoil, unexpected drainage issues — so a contingency allowance is worth including at every stage, not just the first.
02 · What drives the number, beyond finish level
Four factors that move a new-build landscaping budget.
03 · Before settlement
Confirm the gap before it becomes a surprise.
- Read the build contract's specific landscaping, fencing and driveway clauses rather than assuming a standard scope.
- Get a rough written estimate for the compliance-minimum stage before settlement, not after.
- Set landscaping and fencing budgets as separate line items from the house build budget.
- Include a contingency allowance for subsoil preparation, since this is a common new-build surprise.
Budgeting new-house landscaping: common questions
Is there a standard percentage of build cost to set aside for landscaping?
There's no single reliable rule, because it depends entirely on what the build contract already includes and how ambitious the eventual brief is — treating it as its own itemised budget based on actual site condition is more reliable than a rule of thumb.
Can landscaping be added to the mortgage?
This depends on the lender and loan structure — it's worth discussing directly with your lender or broker rather than assuming either way.
Should I get landscaping quoted before or after settlement?
Getting a rough estimate before settlement, even if the work happens after, helps avoid budgeting surprises — final quoting is easier once you can access the site directly.
