There were three established houses in the village by the 17th century, and they were called Kohmo, Rasi and Huhko. Each house was divided into two in the 18th century and subsequently got the prefixes Iso (big) and Vähä (small). Four of the former six houses remain today: Iso and Vähä-Kohmo, and Iso and Vähä-Rasi. The houses still stand on their original 18th century sites. Both of the Huhko houses have been joined to the Iso-Rasi house.
The Kylämäki Village is surrounded by fields, meadows and pasturage, which is a sign of the long-lasting coexistence of man and nature. These traditional biotopes are sustained by pasturing and reaping. The flora of the area is also mapped regularly in order to monitor the development of the species.
