A Subtle Shift That’s Changing Home Values
If you’ve been following Singapore’s property news lately, three letters keep popping up — GFA. Short for Gross Floor Area, it’s the invisible metric behind every condo brochure, valuation report, and launch price tag. And now, thanks to something called GFA harmonisation, it’s being rewritten.
At first glance, it sounds like administrative housekeeping — a technical clean-up between agencies like URA, SLA, and BCA. But in reality, it’s far more consequential. This quiet change to how floor space is measured could ripple through the entire property market — from how developers design homes, to how buyers interpret “value,” and even how older flats are perceived on the resale market.
So here’s the million-dollar question: could this harmonisation make your home worth more — or less — in the years ahead?
What Is GFA Harmonisation — and Why It Matters
To understand what’s changing, we first need to decode three simple letters: GFA, or Gross Floor Area. In essence, GFA represents the total floor space within a property — everything that can be built, used, or sold. It’s the foundation on which developers price units, valuers assess properties, and buyers decide whether they’re getting good value for money.
Until recently, however, that foundation wasn’t consistent. Different agencies in Singapore — URA, SLA, and BCA — each had their own way of calculating GFA. What counted as “floor area” for one might have been excluded by another. As a result, things like air-conditioning ledges, double-volume spaces, and private roof terraces were sometimes left out of the equation, giving certain projects the appearance of more space or better value than others.
That’s where GFA harmonisation comes in. By unifying these measurements across all government bodies, the new rules ensure that every square foot — whether it’s a balcony, a void above your living room, or a narrow ledge outside your window — is now part of the official tally.
The goal is simple but significant: to make property measurements transparent, consistent, and fair. Developers, valuers, and buyers will finally be speaking the same language — one where every inch of space is accounted for, and every price tag reflects the true size of what’s being sold.
How It Changes the Math: Measuring Space, Pricing Value
Before GFA harmonisation, developers had a clever way of making their projects look more affordable — by excluding certain non-livable areas from the saleable size. Spaces like aircon ledges, planter boxes, or high-ceiling voids often didn’t count towards the total Gross Floor Area. That meant the price per square foot (PSF) looked lower on paper, even though buyers were technically paying for some of that “free” space anyway.
Now, under the harmonised rules, every inch counts. Those once-exempted spaces are included in the official floor area, leaving developers with less room to disguise the true cost per foot. The PSF naturally appears higher — not because prices have skyrocketed overnight, but because the way we measure value has become more transparent.
Here’s what that looks like in practice:
| Project | PSF Pricing | Sellable Space (sqft) | Purchase Quantum |
|---|---|---|---|
| Pre-Harmonisation | $2,400 | 990 (includes ledges) | $2,376,000 |
| Post-Harmonisation | $2,600 | 883 (excludes ledges) | $2,295,800 |
At first glance, the post-harmonisation unit seems more expensive — $2,600 PSF versus $2,400. But look closer, and the total purchase price actually dips slightly, because the measured space is smaller and more accurate.
The key takeaway: GFA harmonisation doesn’t automatically make homes costlier — it just changes how value is calculated and perceived. The numbers on paper may look higher, but what buyers are paying for is now more honest, transparent, and comparable across projects.
Impact on New Launch Prices: Smaller, Smarter, and Pricier per Foot
For buyers scrolling through new launch listings, the first thing that jumps out post-harmonisation is the higher PSF (price per square foot). On paper, it looks like developers have suddenly raised prices. In reality, they’re simply working within a new measurement system — one that counts every inch of space, including areas previously excluded from the official size.
That shift has changed the way developers design. With less “free” floor area to play with, they’re re-engineering unit layouts to be smaller yet smarter. Expect to see more compact floor plans, multi-functional furniture, and clever use of vertical space — all designed to squeeze more usability out of fewer square feet. Some developers are also embracing innovative floorplate designs and open-plan configurations to preserve a sense of spaciousness without inflating the official GFA.
The result? PSF prices rise, but the overall quantum — the total price you pay — may stay roughly the same. What’s really changed is perception: buyers are now paying more per foot, but they’re also getting a truer reflection of what that foot includes.
In short, transparency has improved, but affordability feels different. The numbers have shifted — not because homes suddenly got pricier, but because Singapore’s property market is finally speaking a single, standardised language of space.
Impact on Resale Properties: The Unexpected Winners
Ironically, the biggest beneficiaries of GFA harmonisation may not be shiny new launches — but older resale properties. Homes built under the previous measurement rules often boast larger floor plans, higher ceilings, and generous terraces or ledges that wouldn’t fit within the new GFA definitions today. What was once considered “inefficient space” is now becoming a mark of distinction.
As 99.co notes, these older units may see renewed demand, precisely because they offer what new projects can’t — a sense of volume and openness. Buyers who prioritise liveable comfort over compact efficiency are beginning to recognise the value in these pre-harmonisation layouts.
According to PropertyNet.sg, this shift could translate into price resilience or even appreciation for well-located resale condos. As developers trim sizes to stay competitive under harmonised rules, older homes with “bonus” space — from double-volume living areas to spacious balconies — are suddenly seen as rare gems in a market of ever-tighter footprints.
In other words, while harmonisation levels the playing field for new builds, it also redefines what spaciousness is worth — and older homes, with their generous proportions, may emerge as the quiet winners in this new age of precision.
Ripple Effects: Land Prices and Developer Strategy
GFA harmonisation doesn’t just affect buyers — it also reshapes the way developers play the land game. With previously “free” spaces now officially counted, site efficiency drops, meaning developers extract less saleable space from the same plot of land. This directly tightens profit margins, prompting more cautious bids during Government Land Sales (GLS).
As a result, the market may see a short-term slowdown in land auctions or more conservative pricing strategies for new launches. Developers are also compelled to squeeze every square foot smarter, experimenting with innovative layouts, compact units, and multi-functional spaces to maximise value without inflating costs.
In the bigger picture, these shifts align with the government’s long-term goals: a more transparent, consistent property market where pricing reflects true floor space, and design innovation is encouraged. While developers adjust their strategies, buyers ultimately benefit from homes that are better planned, more functional, and aligned with a standardised measurement framework.
Market Dynamics: Transparency vs. Perception
One of the subtler effects of GFA harmonisation is how it changes perception. Buyers scrolling through listings may see higher PSF figures and assume that homes are suddenly more expensive — without noticing the efficiency gains in layouts or the inclusion of previously uncounted spaces. This creates a brief period of market confusion, where perception and reality don’t always align.
Over time, however, the market is expected to stabilise. Buyers will become more savvy, comparing units based on true usable space rather than just PSF, while developers adjust their designs and marketing to highlight functionality and layout efficiency.
It’s a delicate balancing act between transparency, affordability, and perceived value. Short-term, some buyers may hesitate or overpay for appearances; long-term, the standardisation fosters trust and consistency. Developers, in turn, may pivot to smarter floor plans, clearer pricing, and enhanced features to appeal to discerning buyers, while buyers learn to read between the numbers, valuing usability over headline prices.
The outcome? A market that’s more rational, more informed, and ultimately more efficient, even if the first few months feel a little disorienting.
What This Means for You
For Homeowners: Your property’s value may shift in subtle ways under the new GFA rules. Homes with larger, older layouts that include features now excluded from new builds could see resale appeal and potential appreciation. Understanding how your home’s floor space is measured will help you make informed decisions if you’re considering selling.
For Buyers: Don’t be dazzled by PSF alone. Focus on usable space, layout efficiency, and practical features. A smaller unit with smart design may offer better liveability and long-term value than a larger unit whose measurement inflates its price on paper.
For Investors: GFA harmonisation opens a window to undervalued resale properties. Look for older units with generous terraces, high ceilings, or layouts that maximise usable space — these “hidden gems” could outperform newer launches constrained by the harmonised measurement.
Quick Takeaways:
✅ Look beyond the PSF — measure true usable space.
✅ Older resale homes may offer rare spaciousness.
✅ Developers are designing smarter, not always bigger.
✅ Transparency is improving, but perception may lag reality.
✅ Stay informed; your knowledge is your advantage in this evolving market.
The New Language of Space
GFA harmonisation is more than a technical tweak — it’s a redefinition of how we measure, value, and perceive space. The system has become fairer and more transparent, but with that clarity comes a reshuffling of value: what once seemed expensive may be reasonable, and what appeared spacious on paper may now be measured more accurately.
For buyers and homeowners alike, the key takeaway is clear: think in terms of true usable space, not just numbers on a floor plan or PSF tag. By understanding the real dimensions and functionality of a home, you gain a more accurate picture of value and potential.
Looking ahead, this shift promises a smarter, more consistent property market, where transparency isn’t just a regulatory box ticked — it’s a foundation for better decisions, more innovative designs, and homes that truly meet the needs of those who live in them.
