The new duplex house is build with a solid structure in the ground floor, made out of masonry and concrete.The basement functions as a white sag because of the swelled seepage water. From the first floor to the roof, the only stiffening wall is the concrete party wall. 

The upper and top floor is a timber structure. The outer walls in the south, east and west is a room-high trussed beam with door openings. The remaining walls are timber frames. The ceiling above the upper floor is made out of squared timber beams lying side by side.
