This week on Dezeen, we rounded up ten supertall skyscrapers from the world's best-known architects that are set to appear in cities around the world.

Buildings over 300 metres, known as supertall skyscrapers, are becoming increasingly common.

While they were previously predominantly designed by tall-buildings specialists the latest supertalls are being designed by some of the world's best-known architecture studios, including BIG, Foster + Partners, Zaha Hadid Architects and Dorte Mandrup.

In design news this week, French car brand Peugeot has unveiled a rebrand that included a redesign of its lion logo. Introduced to mark a new era of electric car manufacturing, the redesign removed the lion's body from the logo for the first time in almost 50 years.

"The new logo reflects our changing model line-up and new philosophy around living in the moment, and we are very excited to showcase both the logo and the brand identity to our customers this year,"  said Julie David, managing director of Peugeot UK.

This week also saw the launch of Studio Roosegaarde's ultraviolet Urban Sun light. According to the studio, the product was designed to "clean public spaces of coronavirus" to make outdoor spaces safer.

However, in an interview with Dezeen, the studio revealed that the light can only be used at night and people using it still need to wear masks and observe social distancing rules.

In an opinion piece on Dezeen writer Mimi Zeiger stated that it was "time to abolish the architecture critic".

Zeigler made the suggestion as she believes that many newspapers' architecture critics are not equipped to deal with our current time of crisis.

In Tokyo, architecture studio Suppose Design Office completed two monolithic concrete buildings.

A "floating" concrete toilet designed by the studio opened alongside the Sendagaya Station near Tokyo's Olympic stadium, while its founder Tanijiri Makoto completed a home for himself and his family featuring dark living spaces that open onto a sheltered terrace.

Popular projects this week included a private villa in Tulum with a living room that opens on to an outdoor swimming pool, a house in the Netherlands that is arranged around a patchwork of courtyards, and an all-black restaurant in Tokyo designed by Snøhetta. 

This week's lookbook focused on green kitchens.
