With Casa Leopoldo Building, PSA Arquitetura Employs Mashrabiya to Accentuate Distance from the Street and Bring Dynamism to Its Layout
Leopoldo Couto de Magalhães Jr. Street, in São Paulo’s Itaim Bibi district, is home to Casa Leopoldo, a high-end residential development designed by PSA Arquitetura for Bolsa de Imóveis. Situated in one of the city's most coveted addresses, the project is just two blocks from Avenida Brigadeiro Faria Lima and Avenida Presidente Juscelino Kubitschek.
The building offers apartments with three or four suites, featuring floor plans ranging from 335 m² to 821 m². Panoramic linear views unfold from glass-enclosed balconies that span across all façades. The floor slabs extend beyond the railings, emphasizing the design's lightness and elegance, creating the illusion of simply stacked layers.
The building's volumetric design is divided into horizontal segments symmetrically organized to convey harmony and lightness. This concept is further highlighted by the way the slabs appear loosely stacked, as though freely connected by slim supporting pillars, resulting in a cohesive and slender composition.
Horizontal and perpendicular lines form a grid that is denser around the central section of the façade but gradually dissipates toward the edges, allowing the building to integrate gracefully with the city skyline.
The primary challenge for the design team was crafting a high-end project on a lot considered compact for the segment, measuring 1,300 m². “This constraint required the team to perfectly align the program with the needs of future residents,” explains Pablo Slemenson, the firm's founding partner. Consequently, the common areas are streamlined, including a pool, gym, sauna, massage room, and playroom. Instead of a traditional event space, the design features an expansive lobby equipped with a lounge. All spaces were designed to consider and enhance the surrounding urban landscape.
The layout balances integration and privacy. Alongside efficient floor plans—a hallmark of PSA Arquitetura—the project also prioritizes seamless internal circulation. One example is the direct connection established between the service area and the private quarters of each apartment.
To address the proximity between the building and the street—a result of the lot's compact dimensions—the team drew inspiration from Arabic architecture. “We tackled this issue by incorporating a metallic mashrabiya into the façade,” Slemenson explains. “This creates a sense of separation between the interior and exterior, offering greater privacy from the street,” he adds.
The mashrabiya consists of a lattice that also regulates the entry of natural light and ventilation. In Casa Leopoldo, it filters the ground floor's interaction with the urban space, shapes the development’s identity, and underscores the concept of structural lightness. The interplay of voids and solids, in which windows are seamlessly integrated, introduces rhythm and dynamism to the layout.
The mashrabiya contrasts with the robustness of the exposed solid brick cladding, chosen for its durability. Resistant to weather, rust, and degradation over time, the bricks also offer natural thermal and acoustic insulation, helping regulate indoor temperatures and reduce external noise.
Casa Leopoldo marks the 13th project developed by the firm for the same client. Since its inception in 1998, PSA Arquitetura’s partnership with Bolsa de Imóveis has been one of its most enduring and successful collaborations, merging the versatility of exceptional design with São Paulo’s premium locations.
