Iconic old Tiong Bahru Block of flats

I have taken a photo of the distinctive walk-up staircase design with it's unique U shaped and a distinctive circular "pot-hole" close to the Top of the stairs.
Close-by, Block 10A Boon Tiong Road has just TOP. However, it's multi-storey carpark is still under-construction.
But, I have taken several snap-shot of it's "protruding" staircase leading towards the upper floors of the multi-storey carpark.
You can see from the photos that this new carpark had copied the same design from the old Tiong Bahru Flats. Specifically from the photo taken of Blk 28 Tiong Bahru.
