Architect and interior designer Art Gensler

This week Art Gensler and Helmut Jahn passed away

This week on Dezeen, German-American architect Helmut Jahn and Art Gensler, co-founder of the world's largest architecture studio, passed away.

Gensler, above, died aged 85 in his sleep at his family home after a long illness. The American architect and interior designer co-founded Gensler, now the world's largest architecture studio, in 1965.

The studio designed large-scale architecture projects, including the 632-metre-high supertall skyscraper the Shanghai Tower, which is the world's second-tallest building.

Gensler also created interiors for brands such as Apple and Gap, as seen in our roundup of eight of the studio's projects.

Plans revealed for Colosseum amphitheatre's retractable floor

The Italian government approved plans to create a remote-controlled retractable floor for the Colosseum arena in Rome.

The floor, which was designed by architecture studio Labics and Fabio Fumagalli with engineering firm Milan Ingegneria, will replace the original Colosseum floor that was removed in the 19th century.

It will be retractable so that visitors can see the complex of lifts used to bring animals and gladiators directly into the arena beneath the stage.
