There is a particular frustration that comes with shopping for a new apartment in Melbourne right now. The listings look polished, the renders are generous with natural light, and then you check the floor plan. Somehow, what is being marketed as a two-bedroom apartment in 2026 occupies less space than what your parents would have called a generous one-bedroom.
It is not your imagination, and it is not a coincidence. It is the outcome of an industry optimising for its own survival, and buyers are absorbing the cost.
The shrinkage is real, even if the data understates it
The Housing Industry Association has tracked residential floor areas across Australia for decades, and the direction of travel is unambiguous. According to HIA analysis, the average size of new apartments in Australia was just over 118m² in 2022/23, down from 119m² in 2008/09, with the average floor area declining by 0.6 per cent over that period.
That headline number undersells what has actually happened. Aggregate averages smooth over the reality that in the inner-city markets, where most buyers are actually competing, the compression has been far more pronounced. The studios that are dressed up as one-bedrooms, the second bedrooms that cannot fit a double bed, the “study nooks” counted as rooms in marketing copy: none of that shows up cleanly in a national floor area average. The number is telling a polite version of the story.
The HIA notes that the shift toward apartments has been one of the most significant changes in Australian housing trends over the past 30 years. What that framing leaves out is the value judgment embedded in it. The shift toward apartments is not simply a lifestyle preference. For a large and growing cohort of buyers, it is the only option left, and developers know it.
Developers are not villains, but their incentives are not yours
It is worth being clear about why apartments keep shrinking, because the answer is not malice. It is maths.
Land in inner Melbourne is expensive. Construction is expensive. The only variable a developer controls is how many dwellings they can extract from a given site. More dwellings per floor means more revenue to cover fixed costs. Smaller apartments are not a design failure; they are a rational response to an economic constraint being passed quietly onto the buyer.
Rider Levett Bucknall forecasts construction cost growth of 4.0 per cent in Sydney and Melbourne in 2026, with costs that have moderated from their post-pandemic peak but remain well above historical norms. Every time those costs rise, something has to give. Usually, it is the floor plan.
As ProSolution explains, when replacement costs rise faster than market values, developers either stop building entirely, which reduces supply and lifts prices for existing stock, or they pass the costs on, which lifts prices across the board. There is no version of this dynamic that ends with buyers getting more space for less money.
The supply problem is not going away
The people who set prices in this market are not sellers or developers. They are the simple arithmetic of how many people need a home versus how many homes exist. Right now, that arithmetic is working against buyers, and it will for some time.
CBRE research shows Melbourne apartment delivery is expected to average around 9,000 per year over 2025 to 2030, against demand for housing stock likely to average 38,000 per year over the same period. That is not a gap that closes quickly. It is a structural condition that takes years of sustained building to correct, and sustained building requires development economics that currently do not stack up for most projects.
The knock-on effects are already visible. Urban Property Australia recorded more than 7,200 apartment sales in Melbourne’s Inner-City region over 2025, the most active year since 2015 and 42 per cent higher than the 10-year average. That volume is not a sign of a healthy, well-supplied market. It is a sign of pent-up demand being absorbed by whatever stock happens to be available.
Prices reflect it. REIV data shows one-bedroom Inner-City apartments sitting at $380,000, two-bedroom apartments at a median of $635,000, and three-bedroom apartments reaching $1.13 million as at December 2025. Rents are at record territory too. Median Inner Melbourne apartment rents hit $600 per week by December 2025, up 5.3 per cent over the year.
The new-build premium is real and worth questioning
Here is the part of the conversation that rarely gets said plainly: new does not automatically mean better value, and in the current market, there is a reasonable argument that it often means worse value.
CBRE data shows newly built two-bedroom apartments trading at a 30 per cent price premium to older vintages. You are paying that premium for better finishes, improved energy performance, and contemporary amenities. What you are frequently not getting is more space. In some cases, you are getting less.
An older apartment in a well-located, low-rise building often represents a more honest exchange of money for liveability than its shiny, newly constructed counterpart down the road. That is not a universal rule, and building condition and strata health matter enormously, but it is a calculation more buyers should be making explicitly rather than defaulting to new because new feels safe.
What this means for buyers making decisions now
KPMG has forecast Melbourne unit prices to rise 7.1 per cent in 2026, and the fundamentals that underpin that forecast are not going away. Supply is constrained, population is growing, and rents are high enough to support investor demand even at elevated prices.
For buyers, that means waiting for the market to correct itself is not a sound strategy. The conditions producing these prices are structural, not cyclical. What is more productive is deciding clearly what you are buying and why.
Analysis from PropTrack and REIV data points to low-rise boutique apartments under 20 units with low strata fees, close to trains, hospitals, or universities, as the category offering the most reliable rental demand and resale depth. That is not a surprising conclusion, but it is one that gets drowned out by the marketing noise around a new off-the-plan product.
The market is telling a straightforward story right now. Apartments are getting smaller. Prices are going up. And the forces behind both trends are durable. The question for buyers is not whether that is fair. It is what to do about it.
