Corporate Architecture

D+E Soluções em Turnkey is a seal of union between Duomo Architectura and E+Office. It’s not a social reason. It is a joint venture between two companies that have been operating for 20 years in the corporate architecture segment. We unite our core competencies. We associate the same identities and cultures, enhancing an exclusive and professional service.

Through this union, we share our obligations. The Projects, Management and Construction stages are more valued and integrated. With professionals and teams dedicated to each process. These are two companies that have shared the construction site for 10 years. Constantly evolving. D+E is the formalization of this progress. It’s addition and division. It’s stress-free work.
