Room Sizes (Approx)

So to try and get some ideas for my first designs, the most sensible way to tackle this appeared to be to work out which rooms I would need to incorporate in the design. I attempted to break it down as such: Antony - Studio, Exhibition (Internal + External), Bedroom, Bathroom (Ensuite)
Rodrigo - Performance + Recording Studio,, Entertainment (Internal + External), Bedroom, Bathroom (Ensuite)
Pablo - Studio, Entertainment (Internal + External), Bedroom, Bathroom (Ensuite)
Shared - Kitchen, Entrance Hallway, Lounge

By the process of elimination and thinking which spaces can be contained within one another, I worked out the following list of spaces I will need:

Studio x3
Bedroom + Ensuite x3
Kitchen
Lounge
External Exhibition
Internal + External Entertainment

The scanned image below show approximate sizes for the individual spaces.




The next image is the approximate sizes for the shared rooms.
