Hong Kong has proposed doubling the size of a digital technology hub in its Northern Metropolis megaproject and allowing landmark towers of up to 250 metres (820 feet) tall, sparking concerns among environmentalists about risks to migratory birds.The revised proposal for Lau Fau Shan, to be discussed by the Yuen Long District Council’s town planning and development committee on Thursday, would expand the planned digital technology hub from 15 to 30 hectares (6.07 to 12.14 acres), with a total floor area of about 900,000 square metres (90 hectares).Thirty hectares is about one and a half times the size of Victoria Park.Buildings near the planned Lau Fau Shan station on the proposed Hong Kong-Shenzhen Western Rail Link could reach a maximum of around 250 metres to serve as “landmarks” for the area.Depending on floor height, the tallest buildings could range from roughly 50 to more than 80 storeys.Building height limits would taper for sites located closer to the waterfront and other sensitive locations, falling to as low as about 20 metres near the historic Sha Kong Tsuen Tin Hau Temple.
