I think the older readers, should have no problem, but those below 40 or so may find it a bit challenging. So please let them have a go first.

7nine is right. (See comments) It used to be the Spore Polytechnic located at Prince Edward Road and is now called Bestway building. And as you can see from the photo below, it houses the Mediacorp TV12 and other organisations.
But did you know that it was also home to the University of Singapore's** Engineering Faculty? I studied there. This was during the early years of the Engineering Faculty and so they were temporarily housed at what was called the Prince Edward Campus. The main campus was at Bukit Timah and the Medical Faculty was at Singapore General Hospital. When the Kent Ridge campus was completed (in 1977?), the Engineering Faculty was shifted there making it the first faculty to occupy the new premises.
I was in the area last Thursday and decided to pay a visit and have lunch at the canteen. Of course I was armed with my camera and took several photos. Unfortunately, it was an cloudy day, and the pictures did not turn out well.
Anyway, when I have more time, I will blog about my time in this place. I hope they don't tear it down soon. But I realized that some portions to the rear has already disappeared to make way for the viaduct.
** In those days, there were only two universities in Singapore. People referred to them as SU and NU - that's short for University of Singapore and Nanyang University. And, yes, there was also only one polytechnic.
