Twycross ZooThe Challenge Continuing its policy of expansion, Twycross Zoo commenced construction of its new £7,000,000 Himalaya Visitor Welcome Centre in March 2009. Himalaya was designed to emerge naturally from the landscape, and the use of local sustainable materials, ground source heating and landscaping to attract biodiversity were considered fundamental to the development. Design and construction of Himalaya was entrusted to Kier Marriott Construction Ltd, through its Nottingham office.  Various options were considered for the car parking, but bearing in mind that materials used on the previous car parking areas had not always been an unqualified success, the Gridforce ground reinforcement system was selected and approved.  After a 12 month construction period, the Himalaya Centre opened to visitors in March 2010.
