Baby proofing balcony mansion(High rise)?

I have a 2.5yo son who is very active and we are seeking to buy a mansion.

We considered buying a house and mansion, but based on the convenience, location and its price, we are pursuing to push through with the mansion.

However, after so many news about kids falling from high rise mansion, im really scared for my son, and i can imagine my everyday life that if i dont see my son all the time, i’ll be very anxious…
which means taking a shower or even just going to the bathroom for few minutes…

Aside from not letting my son outside the balcony and installing security lock in the balcony door,
Ive considered putting safety net but observing other units, i haven’t seen any unit with safety net on it…

Am i just being paranoid?
I dont want to risk it….

For those who has small children living in the mansion. How do you cope with the anxiety? Any suggestions on child proofing?
