Stop. Before you go further, check this. Most buyers compare prices, layouts and MRT distance. Very few ask whether they can comfortably hold the property through interest rate changes, career changes, or retirement.

**A JadeScape buyer who paid $1,900 psf for a 1,055 sq ft 3-bedroom in 2020 was also paying for 47 sq ft of air-con ledge, concrete she could never furnish or stand in. She didn't find out until a friend's Thomson Reserve floor plan showed her what $0 charged for non-liveable space actually looks like.**

**Direct Answer:** JadeScape launched in 2018, before URA's GFA harmonisation rules. Its quoted strata area still includes air-con ledges and bay windows, roughly 4 to 5% of every unit. On a 3-bedroom at today's $2,350 psf resale, that ledge alone costs an estimated $94,000 to $125,000 for space you cannot use.

## What The Market Is Telling You

JadeScape's 1,206 units split across five bedroom types: 236 one-bedders at 527 sq ft, 403 two-bedders at 646 to 775 sq ft, 265 three-bedders at 904 to 1,152 sq ft, 261 four-bedders at 1,259 to 1,647 sq ft, and roughly 41 five-bedroom and penthouse units at 2,099 sq ft. Every one of those square footage figures is the number printed on the floor plan and the number the psf calculation is built on.

What most resale listings will not tell you is that JadeScape was launched in 2018, four years before URA required Government Land Sales projects to harmonise strata area with actual liveable floor area. That means air-con ledges and bay windows, features every post-2023 launch quotes as $0 because you cannot stand on them, are baked into JadeScape's quoted square footage and therefore into every psf figure you see advertised.

On the 2020 resale example that started this article, a 1,055 sq ft 3-bedroom at $1,900 psf included 47 sq ft of AC ledge, roughly 4.5% of the unit. Scale that to today's pricing: a comparable 3-bedroom at $2,350 psf resale carries an estimated 40 to 53 sq ft of non-liveable ledge, which works out to $94,000 to $125,000 paid for space you cannot furnish.

## What The Market Isn't Telling You

This is the category-defining gap between an agent who sells you a psf number and an adviser who tells you what that number actually buys. Across JadeScape's 11 unit-type variants, the wasted cost from non-liveable strata area ranges from an estimated $49,000 on a 1-bedroom up to $247,000 on a 5-bedroom Suite, the widest gap because larger units carry proportionally larger ledges and bay windows.

This matters most when you put JadeScape's headline psf next to a harmonised project like Thomson Reserve or the upcoming Thomson View Residences. The raw psf gap between JadeScape and a fully harmonised newer launch two stops down the corridor can look like 20%. Adjust JadeScape's resale psf for its ledge, and that gap on a true liveable-psf basis narrows to roughly half that, closer to 10%.

Neither number is wrong. They are answering different questions. The 20% headline gap tells you what you pay per square foot on paper. The adjusted number tells you what you pay per square foot you can actually live in, which is the number that should drive a buying decision, not a listing headline.

## What James Thinks You Should Do

I would not walk away from JadeScape over the ledge issue alone. It is priced into every unit at the estate, so it is not a JadeScape-specific penalty against the rest of the resale market around it, only against post-2023 harmonised new launches.

Where it matters is in a direct, unit-for-unit comparison. If you are choosing between a JadeScape resale unit and a Thomson Reserve or Parcel A unit at a similar headline psf, do the liveable-area math before you decide, not after. A 4.5% difference in usable floor sounds small until you translate it into a six-figure number on a 4 or 5-bedroom unit.

If you already own at JadeScape, this is not a reason to sell. It is a reason to price your exit conversation around liveable psf, not headline psf, especially once Thomson View Residences launches fully harmonised and gives buyers an easy side-by-side comparison.

Secondary — Liveable PSF, Worked Out For Your Unit

I can run the actual liveable-area math on any JadeScape unit type against Thomson Reserve or Parcel A, so you're comparing what you can live in, not just the headline number. No pitch, just the working.

## James's Note

I once measured out an AC ledge on a JadeScape floor plan with a client at a viewing, 44 sq ft on a 3-bedroom unit. She had been comparing the psf against a Thomson Reserve unit for two weeks without knowing that ledge existed. It changed her offer by more than the agent's commission on the deal.

## FAQ

Why can't I compare JadeScape and a new launch on headline psf alone?+−

JadeScape launched in 2018, before GFA harmonisation. Its quoted strata area includes air-con ledges and bay windows you pay for but cannot use. Post-2023 GLS launches like Thomson Reserve and Parcel A are fully harmonised, so every psf you pay there is floor you can stand on.

How much does the AC ledge actually cost a JadeScape buyer?+−

On a 3-bedroom unit at $2,350 psf resale, the estimated 40 to 53 sq ft AC ledge costs roughly $94,000 to $125,000\. Across the 11 unit types at JadeScape, the wasted cost ranges from about $49,000 on a 1-bedroom to $247,000 on a 5-bedroom Suite.

Is JadeScape really 20% more expensive to live in than a harmonised launch?+−

Not once you adjust for liveable space. The headline psf gap can look like 20%, but adjusting JadeScape's resale psf for its ledge narrows the real liveable-psf gap to roughly half that, closer to 10%.

Does the non-liveable space issue affect JadeScape's resale value?+−

Not against other pre-2023 resale stock in the area, since most older District 20 condos share the same pre-harmonisation quoting convention. It matters specifically when comparing JadeScape against a fully harmonised new launch.

Should I still buy JadeScape knowing about the ledge charge?+−

That depends on what you are optimising for. JadeScape gives you a known, tenanted, immediately liveable asset today. A harmonised new launch gives you full liveable-psf value but with pre-completion risk. I walk clients through both sides against their specific timeline.
