This is a row of shops in Shenton Park, Onslow Road. Word on the street is, they were designed by Iwanoff. I have no more info apart from that sorry. They are concrete block, and they do develop some interesting patterns. It seems like it could be Iwanoff as he was just experimenting with the concrete block, yet to fully jump in the deep end. If som very interesting! They are just nice, I dont have much more to add. Go visit them. And there is the SODAA place next door, very very good!
