I recall reading in another thread that it's hard to find a confectioner shop, alchemist shop and mill all on the same plot. I actually have all three on one of my plots in Izzon Crest. I just changed out the T1 PB for a T1 connie and made it open to the public. We even have a water well on the other side of town. And a vault on the castle plot for those who need it.
So help yourself to the use of that plot. It's straight in front of the port pad so you can't miss it. Just look for the Mill. Sorry but I can't open up the silos though. All the silos up there are pretty much in constant use by my guild.
