If you've rented a plot with no ground resources (wood, stone, moss or coffee beans), you can construct a building on it. Every plot has a place for one building only. The buildings can be divided into production and extraction buildings, due to their purpose.
Extraction buildings are various mines and quarries. They are built upon the deposit to increase the efficiency of extraction and the number of workers who can work on it simultaneously. Every extraction building fits for one type of resource.
Production buildings aim at creating the materials or goods of the higher level from the raw materials or processed resources, i.e., tools, construction supplies, means of transportation. Every production building can produce a particular list of goods.
