Covering 340 square meters, the residence on São Paulo’s north coast, in the Recanto do Una condominium in Barra do Una, São Sebastião, has been transformed through a retrofit signed by La Rous Studio, the firm led by architect Larissa Perna. Owners of the property are Bruno Karra, founder of BAW Clothing, and Carol Matiello, a communication and brand content strategy specialist; the couple already have one child and are expecting another.

Kitchen renovation includes Celmar cabinetry and a Taj Mahal quartzite countertop, opening onto the dining and living areas.

Social areas, the reflecting pool and green space stood as the main targets of the intervention on the ground floor. An outdoor kitchen area that previously featured a worn wooden deck was redesigned to connect directly to the pool, completely overhauled, and to the garden, landscaped by Alessandro Terracini. New window frames, with slimmer, more open spans, increased natural light in the social areas.

According to the studio’s lead architect, the project stems from a dialogue between architecture, lifestyle and contemporary identity. Perna said the goal was turning the home into a retreat able to balance São Paulo’s urban energy with coastal calm, informed by close attention to the owners’ habits.

Karra and Matiello share a creative universe tied to urban culture, aesthetics and contemporary lifestyle. Such duality guided the distribution of the renovation, divided between ground floor, second floor and a mezzanine on the top level. Four suites occupy the upper floor, designed with abundant light and views of the surrounding vegetation.

Objects with Stories to Tell

Five chairs signed by names in Brazilian design furnish the living room, including pieces by Sérgio Rodrigues, Carlos Motta and Zanine Caldas. Sérgio Rodrigues’ Tajá armchair and Carlos Motta’s Timbó sofa share space with Luisa Moysés’ Trancoso armchair and Encontro buffet, both made for the Breton brand. Rounding out the selection are Jean Gillon’s Jangada armchair and Zanine Caldas’ Chair I.

Several other pieces complete the scene, among them works from Casa Atika, Estudio Dentro and artist Rosalva Siqueira, whose vase from the Cracas Marítimas collection reinforces the room’s repertoire of Brazilian original furniture. Meanwhile, Hogar pendant light, from Ola Luminárias Acústicas, made of mushroom material and awarded by iF Awards, lights the room with an unconventional material. Wood-and-green-marble fruit bowls from Guatemala, signed by Ola Luminárias Acústicas, add to this curation, alongside Arco tray.

Time Carved in Stone

Perna pointed out that one of the renovation’s main challenges was turning an existing structure into a contemporary house while maintaining and strengthening its relationship with nature. Enlarging the openings and designing new window frames allowed maximum integration between outdoor space, landscape and interior, according to Larissa Perna.

Staying true to that logic, the studio chose Brazilian stone, applied in organic cuts that dialogue with the original building’s Roman stone. Continuity between the preexisting structure and new intervention comes through in this choice, according to the architect’s reading. In the pool, Bari Green marble cladding, of Indian origin, contrasts with the stone’s lighter tones and highlights water as a central element of the outdoor experience.

Unlike the rest of the home, the kitchen countertop received Taj Mahal quartzite, chosen for its durability and distinctive veining. Custom cabinetry carries the Celmar signature, and an open span links the room to the living area, following the integration logic applied throughout the building. Traces of the earlier construction also remain on the facade, restored with the original wood structures preserved.

In the Shade of the Jasmine-Mango Tree

Positioned at the center of the lot, a jasmine-mango tree guided the irregular shape of the reflecting pool’s edge, designed around its trunk. Terracini’s landscape solution turned the tree into a structuring element of the surroundings, preserved since before construction as a point of contemplation between the outdoor kitchen, pool and the rest of the lot.

On the top floor, meanwhile, the mezzanine was conceived as a self-care space, with a gym and an open terrace. Choice of program reflects the couple’s routine: Karra keeps up high-performance running workouts, while Matiello practices yoga regularly. Installed on the lawn, an ice bath underscores this focus on physical recovery, incorporated into the layout as an extension of the outdoor wellness area.

Such emphasis on raw materials also guides the residence’s color choices, Perna noted. Bari Green marble’s deep green creates contrast with the travertine’s lighter tones, while wood and other natural elements sharpen visual integration with the garden and landscape.
