This project transformed into an apartment republic based on the diverse initial desires of the client. The subject was designing a residential unit with approximately 300 square meters area for the parents of a family, four units of 150 square meters area for children, and a possible surplus in the construction license on a 510 square meter land for sale. Proper separation of two-unit floors from each other and rebuilding a common front space of the elevator without damaging single-unit floors were considered one of the principal design challenges.
