Let me try to diagram it:
[build subnet]----[router]----[dhcp server]
- the router will have ip helper address/es configured pointing to [dhcp server]
- dhcp server will be configured to serve a pool of addresses from [build subnet] and desired dns information
Result: Any host attached to [build subnet] and using dhcp will be forced to get information from [dhcp server].
So the answer is "yes", but you also need a router, hope this makes it clearer
