unless you want to bring the few hundreds residence down with you....otherwise, spent your money else where to get a bigger unit. Cheers

guys if you need to hack better get an engineer to point out which wall can be hacked which wall cannot be hacked .... although an experience contractor also can point out ...

concrete elements (columns/beams/walls) ... please do not disturb
brickwall (clay/sand) ... you are welcome to hack ...

Highly not recommended to do it this way. If you disturb the structural element too much, you might cause the building collapses.

normally i would do a huge coring on the ceiling n it looks like a duplex. but i dunno whether its legal onot

Looking at the scenario, i better scrap my idea of buying neighbouring unit

Anyway, learn few construction terms in this thread especially about 'rebar' ...next time talk to contractor also can lagak a bit

when we say a support wall cannot hack, does this mean small hacking for concealed wires also not allowed?

what about drilling a small hole to add a power socket right beside an existing socket?

Small hacking can, but must patch back with non shrink grout.

small small sure can la...
as long as not potong / hack the steel bar inside if wall is consider as loading wall.
if u only hack the surface cement or just remove little cement of the loading wall will cause building runtuh..
then u really need to re-consider still staying at the condo or not ...

ok, but play safe plan a 2nd route which is more inconvenient.

those walls that are part of exterior wall of building, also can do minor hacking for wiring?

cause it's all hacking whether big or small was told cannot hack support walls but never mention big hack or small hack.

also is it ok to drill a small hole tru the support wall to route a wire pass it? any consideration of the hole location, like cannot too close to the wall/ceiling?

If have 2nd route, better use it then.

the 1st route would be ideal unless structural integrity is a concern, if by 2nd route will be longer route, more hacking and certain locations i could not put the sockets without using exposed routing.

what about drilling a small hole for a Cat6 cable to pass, is it ok? coz no other way other than drill a hole tru the window which is not ideal.

For load bearing component, ideally better do not touch it.
But if really no choice then just do it. This is because the structural engineer always allow some safety factor when they do the design.
