What Does It Mean?
GFA (Gross Floor Area) harmonisation refers to URA/BCA rule changes that took effect on 1 June 2023, standardising how strata floor area is computed. Air-con ledges and most private enclosed spaces (PES) and void areas no longer count as saleable/strata area. The practical effect is that new launch units are quoted with slightly smaller strata areas, so headline sizes shrank and PSF figures rose even where the underlying unit is unchanged.
Why It Matters
GFA harmonisation is why a "900 sqft" new launch unit today may feel like an older "950 sqft" unit — the air-con ledge and some void space no longer count. When comparing PSF between pre- and post-June-2023 projects, you are not always comparing like for like, which can distort value judgements.
