A structural designer may soon be selected for a planned 50-m-tall representation of a white horse, which, if realized, would be taller than the Statue of Liberty, sans pedestal. The horse, if constructed, would “overlook” the London-Channel Tunnel Railroad and a new real estate development in Kent, 30 km east of London. The nonprofit Ebbsfleet Landmark Project Ltd. recently chose artist Mark Wallinger’s horse concept and has committed $1.5 million to advance the project through design. Futurecity Ltd., London, is managing implementation, including selection of a structural firm. Photo: Ebbs Fleet
