As part of an innovative partnership called Home Sweet Home (Lar Doce Lar) between multidisciplinary design firm Rosenbaum and TV producer Luciano Huck, the teams went through dozens of Brazilian homes doing dramatic makeovers of interior and exterior spaces. On their 48th home Rosenbaum designed a pretty amazing vertical garden that was suspended in a narrow walkway just outside the house. Response to the garden was so huge the firm quickly released design schematics (in Portugese) detailing how to build one.
