A mixed-use public space comprising a golden cube-shaped kiosk and a giant floating balloon, designed by David Gianotten and Rem Koolhaas of OMA, has been unveiled outside Hong Kong's recently opened K11 Musea.

Kube is at once a place to buy coffee, a place to sit and a place to hold events. The anodised aluminium kiosk, which changes colours as the light changes, opens up as a small retail unit.

Adjacent to it is a seating installation made up of stone cubes at different heights and allowing for the different orientation of the individuals using them.

This configuration is designed to foster serendipitous conversations between individuals.

The area can also be used for events like outdoor performances and cultural programming, with the harbour view providing a scenic backdrop.

For special events, a giant red balloon is inflated to act as an 'urban pin' and mark the Kube as the place to gather.

David Gianotten, managing partner at OMA, said: "The Kube is a multi-functional installation to connect people visiting K11 Musea and passers-by, who share a moment to be fully present to experience the city and possibilities of encounters."
