Why big nations struggle with housing while land-scarce Singapore succeeds — a 2025 deep dive into policy, affordability, and design.

In 2025, a curious paradox stands out in global housing: some of the world’s wealthiest and most advanced economies — including the UK, Canada and Australia — are now among the hardest places to buy a home. Prices have surged, supply has lagged and home-ownership has slipped out of reach for younger generations.

And yet, another wealthy, globally competitive nation with some of the tightest land constraints in the world — Singapore — has managed to keep home-ownership broadly attainable and widely distributed.

Why has this divergence happened? What explains why large nations with abundant land struggled, while a dense city-state succeeded?

This article explores that paradox. High national income alone does not guarantee housing affordability. Sustained accessibility depends on deliberate policy design, long-term discipline and housing systems that prioritise stability over short-term sentiment.

We compare the paths of the UK, Canada and Australia — where affordability pressures have intensified — with Singapore, where home-ownership rates remain among the highest in the world. From there, we distil key lessons for the future.

When Wealth Doesn’t Buy Affordability

Why big nations struggle with housing while land-scarce Singapore succeeds — a 2025 deep dive into policy, affordability, and design.

One might expect that high-income economies should be better placed to provide affordable housing: higher wages, stronger institutions, better infrastructure. Yet the data show a very different pattern.

According to the 2025 Demographia International Housing Affordability Survey, major Australian cities such as Sydney, Melbourne, Adelaide and Brisbane are now classified as “impossibly unaffordable.” In some of these cities, the typical home costs more than nine times the median household's annual income — a level widely considered beyond reach for most buyers.

In Australia, Sydney’s housing market has become one of the least affordable in the world. In 2025, the typical home in Sydney was priced at around 14.7 times the median household income in New South Wales — a ratio that even exceeded Hong Kong in one affordability ranking.

In the UK, although house-price growth has slowed, affordability remains stretched: for example, in England private renters paid on average 36.3% of household income on rent in 2024, above the 30% threshold often used as an affordability guide.

The paradox is clear: being a wealthy country or having high GDP per capita does not guarantee affordable housing. Instead, it appears that structural design of the housing system, regulatory levers and supply mechanisms matter more.

Why the UK, Canada & Australia Fell Into Crisis

Why big nations struggle with housing while land-scarce Singapore succeeds — a 2025 deep dive into policy, affordability, and design.

Let’s examine how the “rich country first” affordability problem unfolded in three major economies.

United Kingdom

The supply response has been constrained for decades by planning friction, heritage restrictions and slow build rates.

The official data show that many households spend far above the 30% income benchmark on housing; affordability is described as “locking a generation out”. 

The scale: The UK’s Office for National Statistics (ONS) found that purchasing an average-priced home in England in recent years would require 8.6 years of average disposable income — a dramatic increase from decades ago.

Policy responses (e.g., help-to-buy schemes) arguably boosted demand without sufficiently addressing supply, adding upward price pressure

Canada

Australia

Housing in Australia has become one of the least affordable globally. In its biggest cities, the typical home now costs over nine years’ worth of a household’s income — far beyond what is considered affordable.

Rents and price-to-income ratios are hitting record levels; for example, to afford the median unit rent, a person in Australia needs to earn at least A$130,000 in 2025 according to a campaign report. 

Australia is facing a major housing supply shortfall. By 2029, the country is projected to miss its target of building 1.2 million homes by roughly 462,000 — a gap that will keep affordability pressures elevated.

Common themes across all three

Credit-fuelled demand, investor participation, weaker public-housing/social-housing buffers.

Supply lags and cost inflation (labour, materials, land) that kept upward price momentum even in slower growth phases.

Policies in these countries treated housing mainly as a market product, not as a public good designed to support citizens.

These countries show that when high incomes, strong aspirations for home ownership, easy access to credit and weak supply planning come together, affordability can break down much faster than expected.

Singapore’s Contrarian Design — From Scarcity to Stability

Why big nations struggle with housing while land-scarce Singapore succeeds — a 2025 deep dive into policy, affordability, and design.

By contrast, Singapore’s outcome stands out: high home-ownership, relatively controlled affordability (in global comparison) and a system designed for resilience. Key pillars:

Public-housing backbone

As of 2024, more than 77% of resident households in Singapore live in Housing & Development Board (HDB) flats.

By one estimate, the home-ownership rate in Singapore climbed from ~30 % decades ago to ~90 % today.

Strong land-use and supply planning

The Government acquires and releases land on a managed schedule, integrates settlement, transport & amenities.
The land-scarcity narrative translates into policy that treats housing not purely as a commodity but as a nation-building lever.
Singapore’s approach is straightforward: the Government actively plans land use, reinvests land value into public housing, and steps in early to stabilise the market. This combination helps keep home ownership widely accessible and sustainable.

Demand management and owner-occupier prioritisation

Relative affordability

In the 2025 Demographia International Housing Affordability Survey, Singapore was ranked among the more affordable markets worldwide. The typical home here costs about 4.2 times the median household income — far lower than the ratios seen in cities like Sydney or London

Though not “cheap” by any means, the number signals that the system is working sufficiently to prevent the extreme multiples seen elsewhere.

Culture of ownership & retirement-saving alignment

The Central Provident Fund (CPF) system channels retirement savings into housing options, aligning incentives for ownership. 

The normative framework encourages ownership rather than long-term renting for citizens.

In short: Singapore didn’t rely on the market to self-correct. It engineered high ownership and controlled affordability through system design.

Why Other Countries Hit the Wall First — and Singapore Didn’t

Putting it together, the story becomes one of structural design and policy discipline.

Where Other Advanced Economies Struggled

As incomes rise, people naturally expect property values to keep increasing. That fuels investor demand. When supply cannot keep up, prices climb even faster, and affordability declines

Markets treated housing as an asset rather than a social platform: the value-investment loop took precedence over housing access.

Governance often responded after the problem, rather than pre-emptively designing for affordability.

Why Scarcity Became Singapore’s Advantage, Not a Weakness

The narrative anchored housing to state policy, not just market dynamics.

Ownership was treated as a collective foundation for citizens (not just an investment).

Supply-side planning combined with strong demand-control (citizen-first, regulated investor entry) maintained balance.

Credit and debt-growth were constrained (loan-to-value, debt-servicing ratio, etc.), avoiding speculative debt bubbles.

In other words: Wealth without careful planning can create instability, while land scarcity paired with deliberate design and discipline builds long-term resilience.

What Singapore Still Needs to Watch

Why big nations struggle with housing while land-scarce Singapore succeeds — a 2025 deep dive into policy, affordability, and design.

We are not immune to pressures. The stable outcome is an achievement — but not a guarantee.

Middle-income squeeze
As private housing prices continue to climb, middle-income households may face affordability headwinds even in Singapore. The system must remain responsive.

Global flows and private segment risk
Investor sentiment, global capital flows and private housing price momentum can still test the system’s buffers. Continued vigilance remains essential.

Right-sizing, ageing population & household size decline
The average household size is shrinking (3.09 persons in 2024) and demographic change is coming. The housing delivery model must adjust to smaller households and ageing residents. 

Affordability perception & sub-markets
While the broader numbers look healthy, some segments (premium private condos, landed homes) may become out of reach for many. Managing market stratification remains important.

Sustaining supply discipline
Even with managed land, the interplay of supply, cost inflation (labour, materials) and global shocks (pandemic, supply-chain) could test housing delivery if unaddressed.

Final Perspective: Deliberate, Not Lucky

The key lesson for policymakers, developers and homeowners is clear: housing resilience is not something that happens by chance. Singapore’s ability to sustain high home-ownership and relative affordability is the result of decades of intentional design and discipline.

In many advanced economies, market forces and rising incomes were expected to support affordability — until they didn’t. The housing challenges we see across developed markets today are less about wealth constraints and more about the absence of long-term structural planning.

For us at PropertyLim Brothers, one point stands out: system design matters. Beyond site, layout or transaction strategy, it is the broader policy infrastructure — land-release planning, financing rules, demand controls and long-term governance — that shapes housing stability.

Owning a home should not hinge on timing or luck. It should be guided by a framework that balances aspiration, accessibility and stability across generations.

For buyers in Singapore, the takeaway is simple: look beyond prices and headlines. Consider the system behind the market, how supply is planned, and how demand is managed. Even in a high-income, land-scarce nation, long-term stability is possible when the fundamentals are sound.
