The diagonal support, which dominates the two sides of the cube, was made for a reason and thus became the dominant element of the building structure. The kindergarten, which consists of basement+ground floor+one floor, is located near the existing building, storey G+4. In that situation, the designed building should be able to mark itself as equal in that place. This is achieved through a diagonal that supports the broken plane of the roof, and overall corresponds to the dominant pitched roof on the existing residential building. In this way, the expected illusion of the size of the projected object is achieved. In addition to this effect, the diagonal bracing and the broken plane of the roof nullify the perspective that decreases on both sides of the building, which is perceived from the main communication, so it is perceived as significantly larger. The position of the birdhouses on the roof part has proven to be effective in terms of directing the view upwards, and also has a positive effect on the dynamic effect of the entire composition.
