Redesign a residential unit

The concept scope: architectural plans layout (in centimeters dimensions) for the building. The building has ground floor, 1st floor, and roof. I don’t need to redesign the ground floor for now but please do consider that I want to add a a private elevator to access the apartment. The first floor and the roof will be a 1 residential unit for my family. The component for this residential unit as follows:

First Floor:
1 master bed room with bath
2 bed rooms with a shared bath room
1 bedroom with a bathroom inside

Second floor/roof
Living room / dinning
Half bath for living
Kitchen

These areas can be placed in either floors where ever it fits:
laundry
office
Storage room
Housekeeper room with bath
