The proposed Flying Garden Tower showcases sustainable, modern architecture in a new urban district development.

In one of the latest developments in sustainable building design, Austrian architectural firm Coop Himmelb(l)au’s Flying Garden Tower proposal has been selected for the Gateway Gardens urban district development.

The design features a tall polygonal tower with hanging greenery that brings nature directly into the space.

Forming part of the Frankfurt Airport City in Germany, the Gateway Gardens district is planned to be a first-class urban node featuring modern architecture and plenty of soothing foliage to provide a fresh stimulus to the region.

Envisioned as a commercial landmark housing many corporate companies in one of Europe’s main transportation hubs, the Flying Garden Tower’s striking polygonal profile will be easily recognisable from its surrounds. Standing 67 metres tall, the building will be highly visible from any part of the airport and nearby roads, as well as from the air.

Environmental efficiency
The Flying Garden Tower’s elliptic shape and orientation have been calculated to optimise the building’s environmental efficiency.

The east and west facades, which are subject to high solar exposure, are protected by the buffer zone of the atriums as tall as the building itself with suspended “flying” gardens. The north- and south-facing facades are optimally aligned in terms of office energy efficiency and were designed to enable flexible and adaptable spatial layouts.

This synergy between architecture and energy design answers the specific requirements of the Gateway Gardens master plan. Instead of cramming in maximum development, it envisages generously spaced open areas with intertwined green elements, allowing its occupants to experience nature in a direct way.
