Is It True No More Wall Hacking For Old Tampines Flat?

[wtc 0]

Hi,

I'd been told recently that HDB does not allow wall hacking for the old flats in Tampines (blk 800s and 200s) anymore? That must go to MP to make noise in order to get it?

Something about that the old flats were built with solid and thick concrete, hacking will caused problems with the upstairs & downstairs neighbours' flat.

Has anyone got permit to hack in Tampines recently?? Thank!
