MDU architetti - misuratori differenziale urbano (urban differential measurers) - is an architecture practice founded in 2001 in Prato (Italy). The partner are Alessandro Corradini, Cristiano Cosi and Marcello Marchesini. The studio’s range of activities goes from urban planning to interior design, and often reaches pure intellectual meditation through theoretical projects developed in the occasion of architecture exhibitions and workshops, where the practice is invited. MDU’s action field are contemporary landscapes, physical and unphysical places on which nowadays men live. The approach starts from a study of reality as seen from an unconventional, transgressive, point of view, searching all the differences that are evident and latent inside it. Architecture takes life from the collision amongst all the alterities of the landascape. The practice has had a high success rate in national and international architectural competitions.
