Work starts on Ukraine waterpark scheme
Construction work has now commenced on one of the world's largest retractable aluminium-domed indoor waterparks in Donetsk, Ukraine, which is due to open early next year.
The 61,000sq ft (5,667sq m) Aquatoria attraction is being developed by Canada-based group, OpenAire, and is intended to help boost tourism to the Donetsk region.
OpenAire's free-standing dome structure will comprise an aluminium truss and will be 86ft (26m) in height, with a retractable design that will open up to 50 per cent of the waterpark.
The design consists of four retractable roof panels, which can open in less than 10 minutes and expose the interior of the attraction to sunlight and fresh air.
"[Our design and engineering team] achieved this ambitious vision with a completely unique, breathtaking design that promises to become an area landmark," said OpenAire president Mark Albertine.
