Hot on the heals of his practice's headline-grabbing Pyramid of Peace, the firm has come up with a startling new design for a 100,000m 2shopping and leisure centre - a scheme observers have already dubbed the 'Broken Brolly'.
The Khan Shatyry entertainment centre, which will sit at the northern end of the new city axis, will rise 150m from its elliptical base and is set to become Astana's tallest building.
Dwarfing the 62m-tall pyramidal Palace of Peace and Reconciliation, the new centre will house an 'an urban-scale internal park' and shops, and is being billed as a year-round entertainment venue.
The building will be clad in EFTE supported by a soaring central mast, which will allow 'light to wash the interior spaces, while sheltering them from extreme weather conditions.'
The park will rise up in series of undulating terraces - the highest of which has been earmarked as a viewing deck - and will boast a tropical water park complete with wave pools, a river and a waterfall.
There are also plans for 40,000m 2of retail space, a range of cafés, restaurants, cinemas, and covered car park facilities.
