This is the floor plan of a simple 4 room flat:
However, its layout will be slightly altered - due to two women:
Yes. Main bedroom will host me! But, I will change the main bedroom's toilet to become a toilet for bedroom #3, which will host my mum and my maid.

So, it will be a main bedroom without a toilet? No choice, I have to change the service balcony to become a walk-way to my "new" main bedroom's toilet - which means that the current kitchen's toilet will have a new door opening. Service balcony will be sealed up to allow a walk-in wardrobe to be built. Kitchen's toilet's original door opening will remain, for guests to use the toilet whenever required. Otherwise, this original door will be locked most of the times.

Kitchen will become pitch dark when service balcony is sealed. So, no choice. Wall that separate the kitchen and the living room will be hacked half to allow more natural light to come in. Too much cooking will cause smoke/oil vapour to escape into living room then (with this new half-wall). So, the other half will be sealed all the wall up with glass.
So, that's a slight change: and an expensive one too.
