On the north west, there were six houses which were stayed in two lines and the road which leads to train station with fences were occupied the west and south parts of apartments. Near the road the farm was situated with some trees.

The bunch of trees were all chopped on the south and were replaced by two apartments on the left hand, with the road between them, stretching from south to north. The new facilities were added, including two factories on the north west and another above the lake. The bridge was constructed between new houses and a factory leading to north.
