The 9th century lake fortress consisted of 16 houses, with a habitable area of 10–30 m². The houses were built of horizontal logs, with gently-sloping roofs, made of spruce or birch bark, as well as turf, and served at the same time as the ceiling. In the middle of the room was a clay oven for heating and cooking. The houses had no chimneys: when the oven was heated, the smoke flowed out of openings in the gables and through the door. The entrance into the house always was located in the left side of the facade. To the right of the entrance porch there was usually a small ancillary structure, where food and inventory were stored, in some of them a small cattle was kept.
