Guild Buildings all max out at level 9. All buildings will be in your Guild Territory. All buildings will cost you resources daily from the Guild Warehouse.
Here is a List of Buildings for your guild and their specific functions.
The first building you create in your guild territory is your Guild Hall. This determines the level of your guild.
This building will hold the resources for you to upgrade the rest of your guild buildings. You will not be able to upgrade any other building without this being the same level as your guild hall, however once Guild Hall is 9 you should not need the Warehouse upgraded past 8 for any other buildings.
This building you need so that you can have more members in your guild. I do not suggest upgrading this building to much as it will just eat resources.
Here you will find your guild skills, all guild skills are passive and they take effect in every battle that you enter. Each skill will need to be upgraded as well as learning each level.
All Skills in your Military Base are based upon a percentage according to level.

Everyone gets excited about their guild shop, you can buy various items in here from potions to gear to resources and vouchers.
In your Guild Shop you can use Guild Coins to purchase gear, troops, potions, recipes, vouchers and other miscellaneous items needed for cooking and forging.
As a Guild Leader you can set limits to how much of certain items each of your members in your guild can purchase. However, remember that not every person in the guild will save guild coins for most of these items.
Guild Shop Gear Section
As seen so far the Gear only ranges from Level 50 to Level 70. (may change with higher Guild Shop, still waiting on results)
Guild Shop Troop Section
Of course the troops will be specific to your civilization.
Guild Shop Treasure Tab
This section is where you can buy Resources, Potions and Vouchers. Vouchers can be set on a limit for each Level a Guild member may be. Example: Leader can purchase 100 a day whereas a new Recruit can only purchase 10.
Voucher respawned daily = [ 44 + (3*CZ count) ] * CZ count
