Semibreve Studio compresses a 55-square-meter (592 sq ft) footprint into an act of memory, organizing the entire plan around a single burgundy cylinder rather than around square footage. Designed by the Brazilian architecture firm Estúdio Clara Nahas for CASACOR São Paulo 2026, the project marks the studio’s debut at the show and functions as a posthumous tribute to the architect’s mother, a professional pianist. The result reads less like a showroom installation and more like a private reckoning staged for public view.
Parque da Água Branca hosts this year’s 39th edition of CASACOR São Paulo 2026, which runs from June 2 to August 9 and gathers 70 environments inside a historic 1929 park where the surrounding buildings predate the city’s vertical sprawl. This edition’s theme, “Mente e Coração” (Mind and Heart), asked participants to treat the home as a space for reconnecting with personal purpose — a brief Estúdio Clara Nahas answered literally rather than as a mood board.
A biographical investigation, not a showcase, is how the studio frames its own CASACOR São Paulo debut. Nahas built the project around her “trunk of memories,” an inventory of objects tied to her mother’s early influence, rather than around a stylistic statement for the show. “My mother was directly linked to the universe of art. I feel I am an architect today only because I was raised in an environment where I could be exactly who I wanted to be,” she said.
The name carries the project’s entire logic: Semibreve, the whole note in musical notation, is the longest note a score can hold, demanding a pause before its full value registers. Nahas translates that sustain architecturally, into a space built to slow its occupants down rather than move them through it efficiently. “Home is the place of recognition; an uninterrupted connection between the tangible and memory,” she said in a statement.
Entry runs backward on purpose. Rather than opening straight into the social areas, Estúdio Clara Nahas designed an inverted flow plan: visitors cross the bedroom and study before reaching the living room. The sequence works as a sensory filter — intimacy comes first, openness second — reversing the domestic hierarchy that usually puts reception ahead of privacy.
One burgundy cylinder does the organizing. At the center of the plan sits a cylindrical volume in a bordô tone, lower than the room’s exposed-beam ceiling and positioned to house the bathroom on one face while its exterior curve is carved into a study desk and vanity on the other. The strategy of resolving an entire floor plan through a single saturated-color volume recurs elsewhere this year — bump studio applied comparable logic in a Genoa apartment, folding one yellow joinery piece around two non-parallel walls to do the same structural and symbolic work.
Todeschini supplies the connective tissue, executing the custom cabinetry throughout, including a greenish Giardino-finish kitchen sideboard that extends into a niche for the architect’s mother’s original vinyl record collection, set against a Da Vinci quartzite countertop. Compressing a full program — kitchen, bedroom, study, closet, and bathroom — into 55 square meters (592 sq ft) without sacrificing continuity is a constraint several studios have tackled differently this year; medioestudio reached a comparable footprint in a Madrid renovation by using color rather than partitions to define zones within an equally compact plan.
Curation doubles as tribute. The dining area’s Arezzo table and Girafa chairs sit beneath a pendant crafted in golden grass by Quilombola artisans, while the living room’s Bowl armchair by Lina Bo Bardi anchors a selection that foregrounds women in Brazilian design and art — from Cristiana Bertolucci’s Cúruma side table to a 1935 woodcut by Maria Bonomi. Architect Maurício Arruda, a longtime collaborator from Nahas’s years in his São Paulo office, led the styling.
Above the study desk, a shelf of hourglasses catches whatever light reaches the cylinder’s red-tiled curve. The objects recur in Nahas’s memories of her mother and now sit as the one detail in Semibreve Studio that asks for nothing beyond attention — no function, no explanation, just a measure of time passing in a room built to notice it.
