This project reuses an unfinished 10 storey steel structure dating from 1969. It was structurally inadequate but its reuse rather than demolition represented a cost saving of 15%-20%. The design concept determined that external elements applied to strengthen the building would function as architectural spaces, which also served to create the additional floor area required for circulation. Internally, two concrete stair cores connect and strengthen floors. On the façade, trapezoidal concrete elements provide additional area and allow the transfer of lateral forces. Similarly, space frames incorporate elevators and service ducts. A new underground auditorium at the base of the building and glass curtain walling complete the project.
