A quick update as I’ve just seen a new view of the Woolwich Tesco development. It shows a tower facing onto General Gordon Square.
Looks as though the square will be surrounded by towers, what with the proposal for a hotel tower by the train/DLR station.
EDIT (Summer 2012): This is not what is now under construction. The tower is not going ahead at this moment. Nor is the twisting building just behind.
