Housing Policy Evidence.
From People Who Build.
We run development, project management and construction in Greater Adelaide — which means we hold first-party data on what actually gets built, what it costs, and how long it takes. We publish research from it and share it with government.
Housing shortage is Australia’s defining challenge, but designing policy is hard without ground-truth. How long does delivery really take? Where are the bottlenecks? Why are costs rising? Our answer comes from projects we deliver ourselves — not from lagged surveys.
Our Evidence Base
The Housing Supply Challenge
Australia’s housing shortage is real. But designing effective policy requires understanding the delivery side of the problem precisely.
Supply Visibility
Planning approvals are visible; what actually gets built is not. Many approvals never break ground, and DA approval does not predict construction timelines or outcomes.
Current approach: annual reports (6–12 months out of date) and voluntary builder surveys.
Cost & Affordability
Median prices rise, but the drivers are hard to see from outside. Is it materials, labour or land? Where does cost sit in the chain? Secondary data rarely says.
Current approach: theoretical pricing models and builder-reported summaries.
Policy Effectiveness
Policy is designed, implemented and then rarely measured against real-world delivery outcomes before the next policy cycle begins.
Current approach: measuring inputs (approvals granted) rather than outcomes (dwellings completed).
The Consequence of Planning Without Data
Some policies work, others do not. You keep both because you cannot tell the difference. Supply remains constrained despite policy intent.
Funding flows to housing initiatives without knowing which has the highest impact, so everything is funded equally.
Builders blame approvals, lenders blame capital, residents defend neighbourhood character. Without ground-truth, the actual bottleneck stays hidden.
The DDDI Difference
We develop, manage and build residential projects in Greater Adelaide ourselves. Our evidence is first-party: real project timelines, real invoice ledgers, real trade pricing, real outcomes — and published, peer-reviewed research built on top of it.
What Our Data Can Help With. Four Applications.
Practical ways planning departments, treasury officials and housing teams can draw on first-party delivery evidence.
Supply Insight
Understand what actually gets built, from someone who builds
- • First-party visibility of a live development pipeline in Greater Adelaide
- • Project-level timelines from planning approval through to completion
- • Ground-truth on the gap between approvals and dwellings actually delivered
- • Delivery-side context for interpreting official supply statistics
- • How long does a townhouse project really take, approval to handover?
- • Why do some approved projects never break ground?
- • What does the delivery pipeline look like at suburb level?
- • Where do projects most commonly stall, and why?
These are the kinds of questions our first-party delivery data can help answer. We don't model supply from surveys — we build it, and we record what happens.
When you combine all four applications:
- •Know the pipeline: Ground-truth on what is actually being delivered (Supply Insight)
- •Know the costs: Where cost pressure really builds (Cost Analysis)
- •Test the evidence: Peer-reviewed research on delivery questions (Policy Research)
- •Communicate clearly: Practitioner briefings your teams can rely on (Briefings)
The Data Behind The Research
We do not rely on high-level estimates or theoretical modelling. Our evidence base is built directly from our own development, project management and construction operations.
