To begin with the price war, it start off from Esparina EC in 2010, Quartz as private launched in 2006 which is before Esparina and at a price much lower.
After Esparina, follow by Austville EC, Prive EC, River Parc EC, ATT, Luxurie, Riversound, boat House, Twin Waterfall EC.
At this point, land bidding was 300+ppr for EC and 500+ppr for private next to MRT in D19.
A hype came in 2012, when Watertown launch in Punggol MRT, a mix dev that is a managed mall with land bid at $1b, nobody knows the actual ppr for the resi components, I estimate around 700+, 2mth into launch online speculate their price over 1500psf, that is partially true with only a few units cross that mark before discount, overall their average price was around 1200psf.
Next, Parc Centro bid at lower land price and ppl though it was going to launch at 800 to 900 psf, but it turn out higher, others like Riversail, Heron Bay EC, Lafesta, Jewel continue this hype in D19, until Treasure Crest EC and Rivercove EC in SK hit 1.1k psf.
Point is, where is all this price hike came from? Demands?
Developer land bidding war?
Or because of a mix dev, then in Yishun North Park mix-dev 1400psf didn't really push the price up in that area except for Miltonia.
EC being sandwich segment between DBSS and PC, it's land bid price is becoming a benchmark, for subsidised housing, the loan amount to a buyer combine 14k income, 1.5mil ppty is just beyond what some had pointed out.
This segment itself had elevate from targeting budget buyer, HDB upgrader to the rich parents first timer kids.
