The site is very central, between an ar- terial avenue, Avenida Faria Lima, and a metropolitan infrastructural axis [road and railway] built on the Pinheiros river shore. Also, the site is exactly under the airport conical zone, meaning all flights coming from Rio de Janeiro fly over the site about each 7 minutes. Pool and solarium were displayed as par- allel volumes. Two columns were located in the 1 m wide gap between them. The 12 m span is faced on one side by beams supporting the pool and on the other by beams that support the solarium and also hang the floor underneath. Structur- ally, the mass of the pool counterweights the volume which holds inhabited spac- es. In other words, water is balanced by the beach. © Nelson Kon t11918
