What’s the ugliest building in Westminster?

Nova Building, Victoria, SW1

As the Nova Building, Victoria, SW1 scoops the national award for ugliest building in the UK for 2017, what is your ugliest building in City of Westminster for you? 

For myself it has to be Burne House, Bell Street, NW1 owned by BT behind the Edgware Rd (Bakerloo line) tube station. It is easily the ugliest building in my neighbourhood. Please see below.
