Need help figuring out rooms...

We are about to close on our second home. It is a large colonial (3850 sq ft with 2000+ sq ft basement). It has four bedrooms upstairs and a maid's quarters downstairs. We are also finishing the basement.

I don't know what room to use for what!!! My husband and I and my 17 month old daughter need a total of two bedrooms upstairs. That leaves two upstairs and the maid's quarters downstairs. Plus we still have a basement.

Where should I put the:
-playroom (basement, right?)
-exercise room (upstairs or basement?)
-my husband's office (maid's quarters because he can make noise when baby is sleeping?)

Any thoughts?

Re: Need help figuring out rooms...

Upstairs
MBR- YOU
Largest next bedroom - DC
Third Bedroom - guest room
Fourth bedroom - home office or exercise room

Maid's room - home office or play room

Basement - exercise room or play room

Will you be home with your DC or have at home care? I would want to be on the same level as the child. I think if they are older 4+ I would be fine with having the playroom in the basement. Is there a way out of the basement besides the stairs?
