With so much construction (new condo, MRT) in Singapore, the bad air and heavy vehicle is everywhere. There was this time while the Ion, 313, Orchard Central, Knightsbrige and Mandarin Gallery was being built, D9 Orchard Road probably had the worst air, you can literally smell and see the concrete dust floating in the air. This locality is Jurong East right near Lakeside? I think the air is pretty ok - if this is bad, then West Coast nearest to Jurong Island would be 100x worse? Sometimes, it's just perception. The grass always look greener at the other side
At least the area is not too dense or crowded with concrete. But $1000psf for 99LH in Jurong is also not my cup of tea lah. If one really want to partake in the Jurong Lake story (which take some time to materialise), I would rather go Hillview/Upper Bukit Timah with FH condos, more exclusive, surrounded by lush greenery/nature reserves and future MRT.
