Commercial land development & project builders — WA

We build commercial WA — from land to handover.

We find the option, prove the numbers, shape the concept, construct it, commission it and manage it as an asset. One team. One accountable party.

Discuss your project See the work

Tested and priced before anyone commits.

Feasibility, buildability and a realised cost, worked through before a contract is signed.

One contract. One accountable team.

Land, design, construction and commissioning under one roof. Nothing is passed across a gap.

Local trades. Senior people on every job.

A considered number of projects, so quality and communication never get diluted by volume.

From land to handover.

Occupied, income-producing and maintained by the team that built it.

Land doesn’t become an asset on its own.

An agent sells the land. A consultant runs the numbers. An architect draws it. A builder prices it. An operator leases it. Five parties, five contracts, five versions of the truth — and the risk sits in the joints between them.

01 Agent Sells the land and moves on. Paid at settlement, whether or not the site can carry the building you need.
02 Consultant Runs the feasibility on assumed costs, before a builder has priced a thing. The numbers look right on paper.
03 Architect risk lands here Designs to the brief before anyone has priced it. When the tender comes in over the feasibility, the redesign, the delay and the cost all land here.
04 Builder Prices the drawings in front of them. Whatever the design missed comes back as variations, after the contract is signed.
05 Operator Leases and runs the building, and inherits every compromise made upstream: the layout, the finishes, the running costs.

Built. Apart. Together.

One team, from opportunity to asset.

Most developments pass through five hands. Site Construct is one: a niche commercial project builder with its own land acquisition and development division, from sourcing the site to managing the finished asset.

The same people who find and prove an opportunity are the people who build it and hand it over.

Working alongside reputable architects, engineers and designers in WA and across Australia, with access to equity and investment firms nationally.

We take care of all the dirty work — subdivide, develop, construct, commission, manage and maintain the investment asset. Nothing is passed across a gap, because there isn't one.

Worth knowing

  • 28 days

    Concrete is specified at its 28-day strength. What went down this month is still gaining strength next month, which is why a programme that treats a pour as finished on the day is a programme in trouble.

  • Your council, not a standard

    Car parking rates come from the local planning scheme, not a national rule. Two identical warehouses in two local governments can owe a different number of bays — and that lands on the site area before anything is drawn.

    The general conditions most Australian commercial head contracts start from. What gets changed in the special conditions is usually where the risk actually moves.
