Two boxes of reinforced concrete , rest fixed connected on the mountainside of one of these islands ; two modern prisms between the large colossal stones of the Brazilian coast . The volumes project outward from the mountain , almost abreast of the beach , in a 8 - meters cantilever . The house , of structural ingenuity , finds balance in the topography of the land , constituting an extensive open doorway and living space in the practically - untouched nature . In the rocks of Paraty , in the dense rain forest of the island , poisonous spiders , discover this orthogonal volume and penetrate the grass that coats the slab . Moving their fore and hind legs quickly , they reclaim the site . The spiders continue on their way into the house and penetrate into an important furniture collection of the XX century designed , among others , by George Nakashima , Luis Barragan , Lina Bo Bardi , Sérgio Rodrigues , Joaquim Tenreiro and José Zanine Caldas . The spiders become lost in the upholstered chair . section 01 © Nelson KonThe inhabitants arrive by boat : the entrance to the house , already protected by the slab , after stepping on the sand , is via a metallic bridge positioned over a crystal - lined reflecting pool . The bridge leads to stairs connecting to the lower volume . This volume contains part of the program of the house : living room , kitchen and service area . The continual internal area has a 27 - meter span and huge glass windows allow for the view , the sea . © Nelson Kon © Nelson KonThe same entrance stairs lead to the upper volume which lodges the bedrooms . In the front part of the house , retractile panels of eucalyptus sticks protect the bedrooms from the sun . The spaces that face the mountain , have small internal patios with zenital lighting and the use of exposed reinforced concrete grants a striking texture to the walls . © Nelson KonThe entire top of the house is covered with terraces , observatories for the inhabitants , for the poisonous spiders , or garden for the sculptures and for the medicinal plants and edible herbs . © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Kon © Nelson Konground floor planfirst floor plansecond floor planthird floor planfront elevationsection 01 section 02
