Designing the building number 17 in the early stages was quite a difficult task for architects because of its massiveness and difficult relief. Therefore, it was decided to break the massive form into several smaller ones. Due to this, we successfully and with caution entered it in the residential complex “Semytsvit”. Thanks to the architectural solutions that were offered to the customer, the building has an unusual planning of apartments. This step makes it unique both externally and internally. Building № 17 is a prime example of how solving difficult problems leads to interesting ideas and good results.
