Brazilian architect Paulo Mendes da Rocha is captured at work in this photoset by photographer Marc Goodwin, which offers a behind-the-scenes glimpse of 20 architecture offices in São Paulo.

The São Paulo series is the latest in Goodwin's project to document architecture studios in cities across the world, following recent trips to workplaces Mexico City, Panama City and Los Angeles.

The set includes the workplace that Paulo Mendes da Rocha, one of Brazil's most celebrated architects, has occupied since 1979. Goodwin said that meeting the 90-year-old architect, who he captured holding an architecture model, as a "highlight" of the trip.

"He was staggeringly youthful for a man nearly 90 years of age," Goodwin told Dezeen. "I am quite sure he has more energy than me and he spoke without pause about several of his projects, walking around the room to point out and pick different models to explain them together with technical facts interspersed with witty anecdotes."

"It felt a bit like meeting Le Corbusier and was a great honour," he added.

The workplace of Studio MK27, founded in the 1970s by Brazilian architect Marcio Kogan, and FGMF Arquitetos, founded in 1991, are among the offices captured.

The photographer, who runs the studio Archmospheres, toured 20 offices in total – providing evidence of its booming architecture scene. He found a number in a cluster together.

"The studios are nearly all within a few blocks of each other in the Higienopolis neighbourhood which is a kind of living breathing museum of modernism," Goodwin said.

"I think that speaks to how closely knit the architectural community is there," he added.

In addition to this, a number of the workplaces host more than one studio: 23 Sul Arquitetura, Casa 14 Arquitetura, Entre Arquitetos, CR2 Arquitetura and Casa RA Arquitetura and Design are all located in one office building, along with structural engineering firm MR2 Soluçoes Estruturais.

Verso Arquitetura's office includes an atelier for a porcelain painter.

Most of the studios are pared-back, with many featuring exposed concrete ceilings and beams, and white-painted walls.

"The spaces where stripped down and functional, perhaps reflecting the economic downturn and political crisis the country is going through," he added. "Each person I met with expressed great concern over the future of Brazil."
