If you'd like to found your own farmers' club, you can do so as soon as you have reached level 10 as well as a free building lot, you can construct a club house on your farm. After the club house is erected on your farm, you can always enter it directly. You are the landlord and can decide who can enter your club house and who can't. You can appoint an assistant and start club quests. If you demolish the club house, it will be automatically constructed on a free building lot of the assistant. If he doesn't have a free building lot, the farmers' club will dissolve.
