The first building that we HAVE TO build is the keep (this building unlocks the ability to build other buildings in the city) for this the following is requried:
Joist: 15 - 10 ash = 1 total = 150
Bick: 20 - 10 sandstone = 1 total 200
Plain facade: 5 - 10 silver = 1 total 50
Brace: 10 - 10 copper = 1 total 100
So 150 ash, 200 sandstone, 50 silver, 100 copper
You are all highly encouraged to help out with his, I'll let you know when all the resources have been gathered. Then we'll start on the next building.
