I've been away fro awhile so was interested to take a look at this and was rather shocked by its appearance. If you're going to experiment with local streets at least have the decency to weatherproof it properly. It's looking pretty shoddy in what I take to be a fairly short space of time. A resin coating would have stopped it looking so cheap so quickly.
I was trying to give them the benefit of the doubt with regard centering as it looked to be so from one end, but decided it was just a shoddy job. It's uneven arrangement also suggests a trip hazard. Is this the level of training for architects these days?
