This week on Dezeen, Gensler revealed visuals for a temporary worship space at Notre-Dame and Rael San Fratell studio slotted pink seesaws into the US-Mexico border wall.

On Tuesday, international architecture studio Gensler revealed its proposal for Pavillon Notre-Dame, a temporary place of worship in the square in front of the 850-year-old cathedral.

It is designed to host church services and markets while Notre-Dame's gothic rooftop and spire is restored, following the fire that tore through it in April.

Meanwhile in the US, architecture studio Rael San Fratello installed three pink seesaws between the metal slats of the US-Mexico border wall.

Designed for children on either side to play together, it is one of five projects by architects and designers in recent years that challenge the divisive structure built by president Donald Trump.

Elsewhere in the US, New York studio SO-IL revealed its proposal for affordable housing in the fast-growing city of León in Mexico. The studio promotes infilling urban sites rather than continually building in the city's poorly-serviced outskirts.

AECOM released visuals of a sports complex for the Los Angeles Clippers basketball team that is designed to resemble a ball "swishing through a net".

Other architecture news this week included Fraser Brown MacKenna Architects obtaining planning permission to build micro-homes in England using shipping containers, and OMA winning a competition to develop a waterfront conference centre in Shenzhen.

The third annual Antepavilion was also completed. Designed and built by Maich Swift, the playful rooftop structure is topped with a light beacon and will be used as a canal-side theatre.

Dezeen revealed it will be hosting its first ever Dezeen Day – an international architecture and design conference that will set the agenda for the global design community.

It will take place at a prestigious central London location on the same day as the Dezeen Awards winners' party, and feature a keynote lecture from a leading international figure alongside panel discussions and movie screenings.

In the design world, London's V&A museum acquired a series of objects from Extinction Rebellion that demonstrate how the activist group has used design to influence public and political opinion.

Sustainable fashion also hit the headlines when Helsinki Fashion Week's founder told Dezeen that the industry "needs to rapidly develop" beyond animal leather, and Norway's consumer watchdog criticised H&M for "greenwashing" its Conscious collection.

Patent applications were filed this week on behalf of a machine called Dabus, which used AI to design a plastic food container and a flashing light.

If successful, it is believed that it will be the first machine to have been recognised as a creator by patent offices, setting a legal precedent.
