It is the C-Houses-8. There are 8 clients who are separated from each others and have different life styles. Each of them expected an organization according to their personalities and usages. This point gave the important idea of the main design. They were expecting to be separated from each other on the whole building system. So they are mostly separated from each other now. Sometimes they touch gentle to each other and sometimes totally separated. A main concrete core holds them together. They are plugged to it. The whole system has both concrete and steel structure as composite system. Materials are changed according to clients/users personalities and requirements.
