We can categorize this as HDB Plus category.. LOL!!!
Actually after reading thru the GLS documents, it does seem that JDen will be plagued with non-stop construction after TOP from surrounding sides at different times. For example the ITH is expected to complete by 2027 and the temporary bus interchange is expected to be in use until 2028. That would mean Plot 2 which is beside J'Den could see construction happening from late 2028 onwards with plot 3 which is in front of ITH commencing 2030 onwards. Plot 1 which is at Genting Hotel side will be the first to be developed likely from 2026 after the site is awarded next year. The big unknown now is the Regional Library site and what will happen after it moves to the ITH in 2027. That plot has the same plot ratio as Jden.
In summary, Jden residents could be enduring non-stop neighboring construction from TOP in 2027 until well into mid 2030's.
