Residents groups such as Open Shoreditch and the Jago Action Group say the scheme would have a "disjunctive effect on the streetscape" and have passed on more than 1,000 letters of protest, including Whiteread's, to the council. In a 2008 open letter, Whiteread and other artists said such plans risked "destroying" a "unique" creative hub. A heritage impact assessment by Richard Griffiths Architects for residents said that the tower would be "alien" to the area and failed to meet conservation guidelines.
