The renovation of this apartment in São Paulo was designed to highlight the art collection and provide comfort and functionality for a family – a couple with two small children.

The neutral tone of the finishes and surfaces, such as the terrazzo flooring with white stones, along with the exposed concrete ceiling and columns, allows the architecture to take a secondary role in spaces filled with paintings, sculptures, and designer furniture. Initially, a dropped ceiling was planned, but during demolition, the flat slab was revealed to be a strong architectural element and was kept in the final design.

The integration of indoor and outdoor spaces was incorporated into the layout to enhance the sense of spaciousness and create a visual connection with the surrounding greenery. The living and dining rooms are integrated, while the kitchen and breakfast area are more secluded, as requested by the clients. The inclusion of a mudroom in the hallway and the use of the private circulation area optimize the layout and provide smooth flow throughout the apartment – especially for the children.

Electrical installations played a central role in the project. While the absence of a dropped ceiling presented challenges, it was also key to shaping the apartment’s architectural identity.
Lighting was handled through magnetic track systems, allowing flexible positioning of light sources so the client can change the artwork placement and always ensure it is well lit. The air-conditioning and invisible sound systems were installed in the wall in such a way that, when in use, the source of the sound is undetectable.

The furniture is a mix of antique pieces and contemporary designs, many of which were created by Arthur Casas himself, such as the Panam sofa and the Côncava sideboard.
