De-Risking Disability Housing: SIL Demand, SDA Mismatches, and Data Insights with Hong Knowling
When investing in or scaling disability housing, how do providers and developers ensure they are building or leasing in areas of genuine demand—rather than falling into oversupplied traps?
In this eye-opening episode of SILosophy, host Tania Gomez is joined by Hong Knowling, founder and director of PPC Urban (Planning Property Consultants). Hong specializes in social infrastructure, town planning, and data analytics, helping investors, developers, and service providers navigate the complex planning permissions, zoning laws, and demand data across Australia.
Hong and Tania break down the common pitfalls in Supported Independent Living (SIL) and Specialist Disability Accommodation (SDA) acquisitions—from $3M property mistakes and biodiversity zoning traps to interpreting NDIS data sets. They also discuss why national data often hides local demand mismatches, the rise of clustered housing models, and how to properly de-risk disability housing investments under NDIS reform.
Key Content Covered In This Episode:
The Hidden Risks in Property Acquisition: Real-world examples of costly town planning, zoning, and environmental study traps (including $80k cultural heritage reports and biodiversity restrictions).

The SDA Supply-Demand Mismatch: Why regional areas with cheap land suffer from oversupply while high-demand metropolitan areas remain underserved.
SIL vs. SDA Market Dynamics: Addressing the 7,000+ SIL providers operating in Australia, the shift toward mandatory registration, and why residential head-leases require proper due diligence.
Clustered Housing Models: How the sector is shifting toward smaller, clustered homes to optimize SIL staffing efficiency without compromising participant independence.
Comparing Disability Housing to Childcare Assets: Capital requirements, pre-leasing structures, planning approvals, and risk profiles across government-regulated sectors.
