The blue roof is made out of parts from various eras: oldest are from the 60's (and so a little deformed), including the uncommon Double Convex / Double Concave; newest are from 2013, from a store's pick-a-brick wall.
Between the town hall and the Octan service station, some city vehicles.
The bicycle paths are red because here in Brussels these are usually sand-red... and I had much more red than sand-red.
Same for the brown poles near the pedestrian crossing: they imitate the wooden poles seen in Brussels.
Yes, there is a bike laying on the ground, it felt before the photo shoot and saw it only after I finished. Same for a small bush in one of the garden. And maybe other things I missed...
