MINUSPLUS is 20 years old. Besides what we think about architecture, who are we together? Who would I be without MINUSPLUS and what would MINUSPLUS be like without me? Our designs are always the result of teamwork, a joint creation. However, during continuous collaboration, individual outlines are not clearly defined. We thought that this birthday would be a good opportunity to respond. Now we are creating together separately. A mashup is a musical work that creates a new, independent work from two or more existing songs. We used this method to create our objects now. One element of the mashup is MINUSPLUS, or a design that is dear to me, and the other element is ME.
