The Madrid studio of Emilio Tuñón has won the bid to expand the architecture school of the Polytechnic University of Cartagena (UPCT). Its design divides the program into three blocks: the existing building, containing administrative services and offices, set to undergo renovation; the library, thought out to take up the the rear part of the latter; and a new block for classrooms, workshops, and laboratories. On the premise of generating flexible open spaces that invite participation, the structure of horizontal trays will leave a series of perimetral galleries open to the exterior. The two buildings, the current one and the new construction, will connect through a walkway on the first floor and an access ramp rising from the ground floor.
