Kaiserstraße, located in Blumenau, Brazil, is a seven-unit residential that redefines urban housing by blending the privacy and richness of a house - verandas, courtyards, vegetation - with the advantages of vertical living. Located on a historic avenue once lined with villas, its stepped, sculpted form meets strict setback rules while maximizing light, ventilation, and panoramic views. Each apartment occupies a full floor with terraces, private pools, and integrated planters that allow mature trees to grow, turning the façade into a living vertical garden, enhancing the city's biodiversity.
