Hi.
You won’t find solution in any of the books. What i feel is that every building should be unique..
It is simple as you don’t have two same personalities, two ditto faces.. then you can’t even have two same buildings. So for that u have to think like your client because the spaces you gonna design is for your client.
So if you are not having your objective (client). Then choose one.. Any great personality, and profession (any thing). And think as that person thinks about every spaces in your unit and i am sure you are gonna end up with a masterpiece.
Lots of luck..
