The building occupies the site located at the corner of Santa Magdalena and Avenida Andrés Bello. For approval, the draft sectional plan filed for interior passages of the Providencia district, which was designed by the architect and town planner GermanBannen in 1973. Costanera Lyon 2 finally completed the interior passage known as Plaza del Sol, which originated in 1978 with Dos Caracoles under the Banner Master plan.
Structure
The structure was designed based on a rigid reinforced concrete frame and core that allows for the transfer of all the vertical and seismic loads through the façade to the foundations by 39-foot-long reinforced concrete diagonals leading down from the third floor to a slab capital 28 inches thick located in the first basement. The proposed structure allows 100% free plans to users. The proposed structure functions as a thermal mass reducing energy consumption used in heating and AC for the offices.
XIV Venice Biennale
Costanera Lyon 2 was selected to be exhibited at the XIV Venice Biennale. For the exhibition, we created a 71-pound exo-structure based on the compression of 21 pieces of marble that transfer the loads to each other to the base, exactly as the building does.
