This week on Dezeen, we revealed that after a decade of driving innovation at IKEA, design studio Space10 has closed its doors as it had "achieved what we initially set out to accomplish".

IKEA's design research lab Space10 closed yesterday, 1 September, after nearly 10 years of producing innovation-led projects on behalf of IKEA.

"Space10 was never meant to last and, after a decade working with IKEA, we have achieved what we initially set out to accomplish," said Space10 co-founder Kaave Pour.

Our AItopia series on the growing impact of artificial intelligence (AI) drew to a close this week as we published Dezeen's policy on using text- and image-generating technologies.

Also in an opinion piece as part of the series, Zaha Hadid Architects principal Patrik Schumacher wrote: "I am not at all worried about facing the newly empowered competition enabled by AI".

To mark World Skyscraper Day tomorrow, we asked readers to vote for the best skyscraper from the past year from a shortlist drawn up by the Dezeen team.

There is still time to vote, with the winner set to be announced tomorrow, 3 September.

In South America, we published a series of pictures by Chilean photographer Cristóbal Palma of the notorious Villa 31 slum in Buenos Aires ahead of its redevelopment.

"It had a funny kind of metropolitan feel because it was so dense, with up to six or seven storeys of construction," Palma told Dezeen. "I got the sense that, although it was very poor, there was a lot of pressure to have land there."

In the US, labour organiser Architectural Workers United filed an Unfair Labor Practice charge against architecture studio Snøhetta.

The organisation claimed that Snøhetta discriminated against employees during a recent union drive.

This week, we also spoke to Apple's retail sustainability lead Rebecca Cully, who explained how the brand is pushing for carbon transparency in the supply chain to reduce the impact of its stores.

"There's so many brilliant products out there in the world, and so many incredible companies that are doing some really interesting things, but as far as innovation is concerned, if we can't identify a partner who's absolutely committed to transparency it's a no-go," she said.

Projects that turned readers' heads this week included a blue-stained timber and terracotta-brick structure in a park in Geneva, a pink housing block in Los Angeles and a Courvoisier bar designed by Yinka Ilori.

Our latest lookbooks spotlighted open-plan interiors where dining tables take centre stage and renovated mid-century homes that marry period and contemporary details.
