vegetation

Bench beneath a tree. A effective, simple and nice configuration.

However it is the tree and the effect is has on the street that is really worth noticing. It leans out and provides shade, it transforms this short stretch of the street into something calmer and more welcoming.
It also reminds me of a paper architecture proposal by the Russian (ex paper-) architect Alexander Brodsky suggesting a retirement home for football players. A courtyard building surround a football field , with a tree placed asymmetrically to provide shade from the sun so the old players could rest.

This one tree suggests to me a manifest of a city consisting of a series of smaller interventions.
