Flats are structurally designed to last 400yrs with safety margin.

You go to 45yr old flat it is still excellent after one round of upgrade.

Even if a cluster of apartment buildings is structurally sound and can withstand the ravages of time for several decades to come, the buildings will still be bulldozed to make room for modern skyscrapers, if the city planners have their say. By modern standards, and esp SG's lofty standard of excellence, aging high-rise buildings are an eyesore. 

The AMK Sers blocks are adjacent to the CTE. Somewhere down the road, I can imagine architecturally wonderful buildings - built on the site of the erstwhile AMK sers flats - greeting motorists cruising along the expressway day in, day out. Travellers will be wowed too, and modernists would surely love that, and that would be in perfect keeping with SG's world-class image. Haha.
