Who We Are

We find it, build it, and guide you through it.

Stone & Clay is a boutique property development and consulting firm operating across the Illawarra and South Coast corridor. We work across the full development lifecycle — from identifying the right site to delivering the finished product — with a small number of clients at any one time so every project gets our full attention.

Our core focus is small residential development — duplex to townhouse scale — where we act as both developer and specialist consultant. We identify opportunities, run the numbers, manage acquisitions, and where engaged, oversee the entire development from DA through to completion.

For clients who need expert guidance without a full development partner, our consulting arm provides independent feasibility analysis, planning advice, site assessment, and acquisition strategy — backed by a trusted network of builders, architects, engineers and real estate agents who validate every opportunity before you commit.

What We Do

From brief to unconditional

Every engagement is bespoke. We don't list properties — we find, analyse and secure them on your behalf, with full due diligence at every stage.

01

Site Identification

We source on-market and off-market opportunities across our coverage corridor, screening against your budget, development type and return requirements before you see them.

02

Feasibility Analysis

Detailed financial feasibility modelling accounting for planning constraints, construction costs, infrastructure requirements and realistic end values — not back-of-envelope estimates.

03

Technical Due Diligence

We coordinate site surveys, traffic engineers, slope assessments and infrastructure reviews. No surprises after exchange.

04

Acquisition Management

We negotiate on your behalf with full awareness of local market conditions, planning risk and comparable transactions — protecting your position at every step.

05

Off-Market Sourcing

Our direct outreach program identifies landowners considering selling before they list, giving our clients access to opportunities that never reach the open market.

06

Planning Advisory

Deep knowledge of the NSW Low-Medium Rise Housing Policy changes, local LEP/DCP controls, flood constraints and zoning — we know what can actually be built.

How We Work

A rigorous process. Every time.

We work with a limited number of clients simultaneously. This allows us to be genuinely thorough — not just fast.

01
Initial Brief

We understand your investment parameters, return expectations, preferred development type and risk tolerance before we start looking.

02
Site Search

Active search across both listed and off-market opportunities. We screen each site against planning controls, topology, services and preliminary feasibility.

03
Due Diligence

Site visits with builder and architect, survey coordination, infrastructure assessment, traffic engineering where required. We validate before you commit.

04
Acquisition

Offer strategy, negotiation, conditional period management and unconditional exchange. We see it through to settlement.
