Located in the capital of São Paulo, in the neighborhood Jardim Paulista, Edifício Therezinha was the client 's choice for her new home. Built in the 1970s, featuring modern influences and rationalist touches, the facade design stood out for the abundance of windows, allowing generous sunlight into the apartment.

The office's role in helping select the property made a significant difference, as layout studies were conducted during the purchase negotiations, ensuring the client the ability of the project to meet her needs. With an area of 134m2, originally the apartment consisted of two suites, one bedroom, a restroom, a living room with a balcony, and a kitchen integrated with the laundry.

The client's initial desire was to integrate the entire social area and create a spacious and cozy suite. For this purpose, the project was conceived with a focus on tranquility and harmony between spaces, allowing visual permeability throughout the apartment. The renovation project integrated the balcony with all spaces, offered the possibility to adapt the TV room and office into a guest room, restored the original window frames, and created an intimate area with a bedroom, closet, and bathroom.

During the demolition, only one wall was maintained, and a single plumbing wall was constructed, serving the entire apartment. In the social area, the former bedroom was integrated into the living room, featuring a versatile layout that can be adapted to a TV room  and office or a guest room, through the complete closure of the space using a sliding freijó wood panel.

In the kitchen, a support counter was created to facilitate quick meals and ensure interaction with who is cooking. The social areas are delimited differently than usual, as the exposed concrete beams on the upper slab define the layout.

In the intimate area, the project created a single generous suite with a closet and a bathroom with an immersion tub. The central element of the project is a curved bench that runs through the entire social area and the client's room, born from a challenge encountered during demolition.

The window frames of the dining room and bedroom have an inverted beam that prevents internal-external integration at the same level. Therefore, the idea of creating a curved bench, providing visual harmony to the project, enhancing the spatial qualities of the environment, and creating new gathering spaces.

The client was actively involved and detail-oriented in all the project processes. With clear intentions and references, her briefing emphasized the use of natural materials to bring warmth to the spaces and visual comfort through subtle tones. The predominant materials in the project were: Wood, present in freijó carpentry and tauari flooring. Beige cement in the balcony floor, bench and kitchen counter. Exposed beams and pillars with treated concrete surfaces, exposing the building's structure. Terracotta ceramic cladding on the balcony railing.

Cementitious cladding on bathroom walls. Terrazzo flooring in wet areas (bathrooms, kitchen, and laundry). Replacement of old frames with iron frames following the original facade design. The combination of these materials resulted in a neutral natural color palette, bringing a sense of lightness and harmony to the environment. Carefully selected furniture contributes to the apartment's coziness, combining raw woods in tables and benches with the delicacy of the velvet couch (Casa Ática).

The curation includes a mix of contemporary furniture (Estúdio Orth, Casa Ática, Ries Estúdio) with designed furniture by the architectural office (dining table and office table) and classic design (Percival Laufer, Wishbone Chair, Lina Bo Bardi, Cesca Chair). The presence of greenery and vases both on the external balcony and internally, blend with Brazilian and Argentinean artworks, the client's country of origin.

The lighting design predominantly uses indirect fixtures, revealing the use of direct fixtures only for specific areas for manual tasks, such as the office desk, dining table, laundry, and kitchen.
