Land Selection

Finding the Right Foundation

Typical Duration: 2–6 Weeks

STAGE OVERVIEW

Land Selection

Not all land is equal. A block may appear perfect on paper but present significant engineering or planning challenges that add tens of thousands of dollars to your build cost. Our team evaluates land from a construction and design perspective before you commit, assessing orientation (north-facing living is ideal in South Australia), slope and retaining requirements, soil type and potential reactive clay issues, access to services (sewer, gas, NBN), proximity to bushfire attack level zones, and applicable council Development Plan overlays. For knockdown-rebuild projects, we conduct a thorough assessment of the existing structure and any heritage or character overlay restrictions that may affect your design freedom.

STAGE CHECKLIST

What Happens at This Stage

  • Site orientation analysis (solar, prevailing winds)
  • Slope and retaining wall requirements assessment
  • Soil report review (Class A through P classification)
  • Council zoning and overlay check
  • Bushfire Attack Level (BAL) assessment where applicable
  • Existing services and connection cost review
  • Knockdown requirements (if applicable)
INSIDER TIPS

What to Know at This Stage

01

A soil test (geotechnical report) should be conducted before purchase wherever possible — soil class dramatically affects slab and foundation costs.

02

Steep blocks can add $50,000–$150,000 to building costs due to retaining walls and site preparation.

03

Check if the block is in a Regulated or Significant Tree zone, as removal can be costly and time-consuming.

FREQUENTLY ASKED

Questions About This Stage

Absolutely. We strongly encourage you to involve us before signing a contract on any block. Our pre-purchase site assessment could save you from a costly mistake.

A geotechnical (soil) report classifies the land's reactivity and bearing capacity. This determines the type and cost of your slab or foundation system — potentially adding tens of thousands if highly reactive.

Yes — some of our most striking homes are on challenging terrain. We design to work with the landscape rather than against it, but we are transparent about the additional costs involved.
