This week Neri Oxman unveiled an AI-optimised conceptual skyscraper

This week on Dezeen, design studio Oxman revealed designs for a conceptual skyscraper formed of a stack of planted platforms.

Named Eden Tower, the structure was designed using a system devised by the studio called "ecological programming", which aims to optimise green architecture.

The project was unveiled at the opening of Neri Oxman's Foster + Partners-designed studio in Midtown Manhattan, which houses a production workshop and wet lab.

In architecture news, the Pan Pacific Orchard skyscraper in Singapore by architecture studio WOHA was named the world's best new tall building by the Council on Tall Buildings and Urban Habitat.

The building was described by the Council on Tall Buildings and Urban Habitat as "a hotel in nature" and was chosen for its demonstration of Singapore's sustainable vision.
