The Gallery | Progress on Kolkata's community space in the sky

Images have been released showing progress on the project to build a community space 100m above the ground in India.

Deya – which means cloud in Bengali – is being built between two residential towers in Kolkata.

The four-storey connecting structure will contain a range of facilities for residents including a party deck; swimming pools; sporting facilities such as basketball court and a putting green; a boardroom; and a cinema.

A 12-hour lifting operation took place last summer. 

Hossein Rezai, group director at earthquake engineering specialists Web Structures, which is working on the project, said: “The Deya is not directly connected to the towers. It is a completely separate structure and is allowed to move independently by resting upon four isolator bearings.

“There are two on each tower and each weighs 14.5t. These bearing sit on concrete plinths that in turn rest on a reinforced concrete slab over 2.5m-deep structural steel girders.

“The bearings themselves are specially designed and tested with energy dissipation to ensure that after an extreme earthquake or high winds that the Deya returns to its original position and the tower structures are not damaged.”

This video from last year shows the lift taking place:
