Illawarra & South Coast Specialists
Stone & Clay is a boutique property developer specialising in small residential projects across the Illawarra and South Coast — duplexes, terraces, and townhouses — built on deep planning knowledge and genuine local expertise.
Who We Are
Stone & Clay is a boutique property developer based in the Illawarra, specialising in small residential projects — duplexes, terraces, and townhouses — across the Austinmer to Huskisson corridor.
We develop our own sites and, for a small number of select clients, we provide end-to-end development consulting: from site identification and feasibility through to due diligence and acquisition management.
We bring together builders, architects and civil engineers to assess every opportunity thoroughly — via CDC or DA — before any commitment is made.
What We Do
We develop our own projects and guide a select number of clients through their development journey — from first brief to unconditional exchange, with full due diligence at every stage.
We identify on-market and off-market development sites across the corridor, evaluating each against planning controls, development potential and financial return before shortlisting.
Detailed financial feasibility modelling, accounting for planning constraints, construction costs, infrastructure requirements and realistic end values — not back-of-envelope estimates.
We coordinate site surveys, civil engineers, slope assessments and infrastructure reviews — identifying constraints before exchange so there are no surprises.
We manage the acquisition process on behalf of clients — offer strategy, negotiation, conditional period management and unconditional exchange, informed by deep local market knowledge.
For select clients, we provide end-to-end development consulting — site evaluation reports, feasibility studies, financial modelling and return on cost analysis tailored to your brief.
Deep knowledge of the NSW Low-Medium Rise Housing Policy, local LEP/DCP controls, flood constraints and zoning — including both CDC and DA pathways. We know what can actually be built.
How We Work
We work with a limited number of clients simultaneously. This allows us to be genuinely thorough — not just fast.
We understand your investment parameters, return expectations, preferred development type and risk tolerance before we start looking.
Active search across both listed and off-market opportunities. We screen each site against planning controls, topology, services and preliminary feasibility.
Site visits with builder and architect, survey coordination, infrastructure assessment, civil engineering review where required. We validate before you commit.
From offer strategy and negotiation through to conditional period management, CDC or DA lodgement and project delivery — we see every stage through.
Selected Work
The Edge We Bring
Mt Ousley, NSW
Two side-by-side blocks. Both too narrow individually to build anything more than a single dwelling. Our deep knowledge of the planning controls combined with a relationship with the local real estate agent gave us early sight of the neighbour’s block coming to market.
By moving quickly and securing both lots, we unlocked an amalgamated site capable of carrying four terraces — a result that was simply invisible to the market.
The insight
Two blocks that couldn’t support a duplex individually became a four-terrace site once combined. Planning knowledge plus agent relationships equals opportunities that never reach the open market.
Blackbutt, NSW
This site had been on the market for over a year. Every buyer who looked at it saw the same thing: a duplex site. Some walked away; others put in low offers. The listing sat.
We saw something different. The site sits within a newly mapped Low-Medium Rise (LMR) zone. Our access to expert planning consultants confirmed what the controls actually permitted: a triplex, not a duplex. One extra dwelling changed the entire financial equation.
The insight
A year on market at duplex pricing — unlocked as a triplex through precise understanding of the NSW LMR mapping and access to the right planning expertise.
