Housing governs the maximum population your castle can hold. Your keep will house some peasants, but when it is full you will need extra housing for additional workers. Each hovel placed will increase the castle’s maximum population. Peasants are needed to work in your farms and workshops. Any spare peasants will stand around the camp fire waiting for work. There are 6 sizes of hovel available. The largest hovel houses 10 peasants and the smallest only one person. The size of a hovel is dependant on how far from the keep you build it. The largest hovel can only be placed right next to the keep, but the tiniest hovels can be built far away from it. How many hovels you build is a balancing act. Building lots of hovels will mean you have more peasants around your camp fire available to work, but all those peasants will be consuming food, which can quickly empty your granary.

A market is vital for oiling the wheels of your castle economy. Along with taxing your population the market is the only other way to generate gold. The market allows you to buy and sell all goods from a single location. Clicking on the market will bring up the trading panel. On it, you can view the goods the traders are offering before deciding what you wish to buy or sell. The market also features some advanced buying and selling tools not available in the stockpile, granary, armoury and keep. By setting an autobuy and an autosell price for a good, the market will automatically buy or sell that good at that price, allowing you to concentrate on other areas of your economy.
