This street is right in the city centre of Antwerp. It has decent density, human proportions, a good width between buildings, greening, space shared between transport modes, pedestrian and cycle friendly, decent materials.
In many ways it's nothing fancy, just a really good street.
Postscript: I subsequently discovered that this is a city-wide project to incorporate 'garden streets' (Tuinstraten) incorporating sustainable urban drainage, urban greening and biodiversity. Read more about Tuinstraten here
