The Kurssi house was moved to Seurasaari from Kuortanee, Southern Ostrobothnia. The house was owned by the same family from the 1700s until 1915, when the museum bought the main building. The Kurssi house consisted of nearly 20 buildings, including a stable, granary, barn, sauna, well, hut, barn, wood shed, and a threshing floor.

The centre of the two-storey building was a room where people cooked, ate, slept, made crafts, danced and played.

The barn in the courtyard was not originally part of Kurssi house. The barn is from a house in Sippola, a neighbouring village of Kurssi. Today, there is a children's summer house downstairs, where children are allowed to play.
