IP Scheme: Different Vlans & Subnets on each floor for same Data / Voice/wireless

Dears, 

I'm designing IP Scheme as below, so just want to know that it is fine or will have some issues?

Floors of each branch have different Vlans and Subnets (3rd octect) for the same like Data / voice /wireless. 

Vlan 10 (Data)  ground F 10.10.10.X

Vlan 11 (Data) 1st F 10.10.11.x

Subnets divided by physical buildings is better.  

If sub-divided by floors, what guarantee do you have that a wireless client won't get an IP address meant for floors THREE FLOORS UP/DOWN?

Except of wireless, what about data /voice?
