If ever there was an opportunity missed to plant proper trees in a London street, Exhibition Road was it (Buildings February 3). It will not, I hope, be taken by future designers of streetscapes as a good example of urban landscape architecture.

Rather than broad, high trees down the centre of this wide boulevard, we have a line of narrow metal masts. No delicate tracery of branches in winter and soft canopy of leaves in summer — instead, something cold, clinical and heartless. It’s very disappointing but perhaps we learn from our mistakes.
