Why Chuan Park Is Pre-Harmonisation
The en bloc sale date determines which rules apply — not the launch date. One critical timeline explains everything:
Every D19 Development — Harmonised or Not?

True PSF Comparison — Adjusted for Liveable Area

How Chuan Grove's Harmonised Status Benefits You
- No AC ledge charge — $80K–$181K savings vs Chuan Park
- Lower BSD base — purchase price on smaller sqft = less stamp duty
- Better rental yield — income vs. 100% liveable purchase price
- Transparent resale — apples-to-apples with all future harmonised projects
- Every sqft in your title is sqft you can walk on and furnish
- Cleaner floor plans — no oversized bay windows padded into strata
- More efficient living rooms — developers maximise actual floor plate
- Better-shaped rooms — AC ledge protrusions eliminated by design incentive
The Comparison Trap — Why Most Buyers Get This Wrong
When Chuan Park launched in November 2024, I watched the queue form before sunrise. These were families from Serangoon and Bishan who had been waiting 14 years for a new condo next to Lorong Chuan MRT. What nobody explained clearly at the showflat was that the quoted floor area included the AC ledge — a slab of concrete outside the window that nobody lives on. A 3BR buyer paid approximately $127,000 to $142,000 for that ledge.
Chuan Grove gives those same buyers a second chance — and a better one. Not because the location is superior (it is next door). It is better because every square foot at Chuan Grove is liveable floor plate. At $2,600–$2,700 psf on a harmonised basis, Chuan Grove is effectively cheaper per functional square foot than what Chuan Park buyers paid.
My advice: do not compare quoted sqft. Compare liveable sqft. Add up what you are paying per room. I will run that comparison for you before you sign anything.
