Some believed they had pinpointed the exact location.

One user wrote: “Serangoon North Avenue 3. Some of the nicest and biggest flats in that cluster, but also some of the worst accessibility by public transport, even till today.”

Another added: “Looks like Block 550+ at Serangoon North Avenue 3, but it was probably filmed from a different block.”

Armed with those clues, the OP did some detective work and came up with a theory about the filming spot. “I did a bit more exploring and think that the MV was probably shot from Blk 550A (the MSCP) facing east.

“You’ll see the following blocks from left to right: 548, 549 (the block at the back that you were referring to), 550 and 554. Mavis Hee was probably standing on the rooftop of the MSCP, or perhaps the MSCP was not yet built at the time of filming.” MSCP refers to multi-storey carpark.

Turns out the mystery had been bugging more than one person.

One commenter wrote: “[This is] a question that I have had for quite a while. Love this era of flats much more than the flat and boring blocks of the 80s. The 90s flats really feel like the best era.”

Another suggested: “You should do a YouTube video of your find.”

So, would you have guessed Serangoon North?
