Alliance's Buildings

[rocky]

If a player know all the information about the Alliance's Buildings I would be happy to know what is the price for each building and how it work for the contracts ? Do you need to put gold and silver at each time you renew the contracts for each building ? And is it the same with the Design Center Building ?

Thank's for your help in advance
