Suggest a solution(s) for more than 16 VLAN’s scenario?

Scenario: We have to set a business center on a complete floor, it have 21 different Cabins / offices, cisco access points, one internet line will be shared, one server will be shared by all cabins/offices but privacy HAS be maintained while using internet and network resources. As I can creat on 16 Vlans (maximum), I need other plus best solution(s)s for the above. Thanks
