This week on Dezeen, the Serpentine Pavilion by Japanese architect Junya Ishigami was unveiled in London, but the event was overshadowed by the unexpected resignation of Serpentine CEO Yana Peel.

Built to resemble "a hill made out of rocks" Ishigami's pavilion has a roof made up of 61 tonnes of Cumbrian slate. It is held up by 106 thin columns in a grid pattern.

The architect told Dezeen his aim was to "make the architecture part of the landscape rather than making it an independent building".

The pavilion opening coincided with the resignation of chief executive Yana Peel.

Peel cited a "concerted lobbying campaign" and "toxic personal attacks" against her and her family as the reason behind her decision to quit.

Yinka Ilori is the man of the moment with two new projects this week, following the opening of The Colour Palace last week. The London-based designer created the exhibition design of a Somerset House show celebrating 50 years of black creativity in the UK.

Meanwhile in the south of France, Ilori provided a place for strung-out ad execs to release their inner-child in a playground featuring a see-saw and roundabout emblazoned with popular Pinterest colours.

In the US, Studio Gang revealed new renders of its extension to the American Museum of Natural History in New York, which will add further galleries, a theatre, a library and classrooms for visiting students.

On the west coast, Second Home's LA outpost will open in September this year designed by Spanish practice SelgasCano, who revealed plans this week. Located in West Hollywood, it will feature vibrant yellow working pods and plenty of greenery.

Also in architecture news, Foster + Partners revealed plans for a project further north up the Pacific coast. Proposed for Santa Clara, the Uber Air Skyport will provide a hub for the company's proposed flying taxi service, due to launch in 2023.

Elsewhere, Japanese architect Sou Fujimoto completed a project with French collaborators with Nicolas Laisné, Dimitri Roussel and OXO Architectes. The L'Arbre Blanc tower in Marseille, France, features jutting balconies.

In fashion, designers branched out into new territory. Roksanda Ilincic designed a penthouse apartment in the Gasholders development in London's King's Cross.

Set over three levels, the apartment is awash with the blush pink, berry and navy tones that forms Ilincic's "brand DNA".

Elsewhere in London, Royal College of Art student Laura Kraup Frandsen chose not to present a graduate collection, instead staging a "die-in" demonstration with climate change activists Extinction Rebellion and piling up the studio's textile waste from the last few months.

Projects enjoyed by readers this week included a selection of small Japanese houses that offer complete privacy, a speculative aircraft with V-shaped wings from KLM and a Norwegian cabin that provides a year-round retreat for a family of five.
