The National Theatre is on the South Bank of the Thames. Here is a view, looking East from Waterloo Bridge.
As you see, there are gates across the walkway. The Theatre is closed, and the walkways are closed.
My drawing shows the empty theatre, and the empty walkways. The theatre restaurant, which is on the left of the drawing, is also closed and empty.
The walkways, in true 1960s style, are at “podium” level, above the traffic. Below me as a drew, people walked and cycled, and traffic passed on the nearby road, Upper Ground. Grass and buddleia grow in the cracks. Life continues, but at a different level.
This drawing is 25cm by 16cm, 10 inches by 6½ inches on Arches 300gsm watercolour paper. It took 1½ hours. I did a preliminary sketch first, shown in the work-in-progress photos below. The colours are Buff Titanium, Neutral Tint, and Lunar Earth, all Daniel Smith watercolours, over De Atramentis document black ink.
I’ve drawn the South Bank before:
