Context: Ageing, Disability & Housing
This page provides a single-page orientation to the social and policy context that motivates the thesis. It is deliberately brief: every claim summarised here is developed at length in the chapters and appendices cross-referenced below. Readers seeking the full evidentiary treatment should follow the in-text wikilinks rather than treat this page as a substantive narrative.
Introduction
The thesis is set in the intersection of an ageing Australian population, the Specialist Disability Accommodation (SDA) reform programme, and the persistent under-supply of housing that fits the bodies and lives of older and disabled occupants. This intersection makes dwellings subject to constant, multi-authored change — shifting occupant needs, standards revised on their own cycles, and turnover among the actors who design, certify, and modify the home — so that an ostensibly local change tends to cascade into global re-checking across the drawings, schedules, and certificates that hold the dwelling together. Making such adaptation tractable is the design problem the thesis takes up; its name for the integrative response is representational governance. The full problem-context narrative is developed in Chapter 1 §§1.1–1.3, where the research problem, gap, and motivating social conditions are stated.
The Ageing Population
Australia is undergoing rapid population ageing, with the share of residents aged 65+ projected to rise materially across the thesis horizon. Ageing-in-place is the stated policy preference at Commonwealth, state, and territory levels, yet the housing stock that older Australians actually occupy was largely designed without regard to age-related changes in mobility, vision, cognition, or care need. The literature establishing these demographic and policy parameters is reviewed in Chapter 2 §2.1 (Housing Need as Dynamic Fit), which frames ageing as a continuous re-fitting problem rather than a discrete accessibility threshold.
Housing as Social Infrastructure
Housing in this thesis is treated as social infrastructure: a system whose performance is measured not only by unit count but by the optionality it offers across an occupant’s lifecourse and across the population it serves. The theoretical framing of housing as a substrate for bounded optionality and modular re-configuration is developed in Chapter 2 §§2.4–2.9, with the underlying complexity- and modularity-theoretic foundations laid out in Chapter 3.
The State of Australian Housing
Australian housing supply is characterised by stock dominance of detached single-storey dwellings, low rates of universal-design uptake outside SDA-funded streams, and substantial regional variation in availability and price. The empirical baseline against which the thesis’s artefacts are evaluated is summarised in Chapter 8 (the empirical substrate) and the corpus appendices (appendix-data-index).
Barriers to Accessible Housing
Barriers to accessible housing are simultaneously regulatory, representational, and procedural: standards are written in graphic form that resists machine reading; deontic force across clauses is uneven; designer workflows discard the structural information needed for downstream verification. The representational diagnosis is the substantive contribution of Chapter 5 §§5.1–5.2 (the standardisation schema) and Chapter 7 (PlaniSyn and RecPol notation), with the procedural-generation response in Chapter 9.
Conclusion
The contextual conditions sketched above motivate the thesis’s central design-research question — how to govern accessibility as a representational system rather than a discrete compliance check — and structure the artefact suite that follows.
