I wonder if it will take off!
A trendy cube style commercial shop's were created in London's Shoreditch area, which over the last 5 years or so became a very trendy area. So someone created little shops, really tiny, in cube shapes, and they rented it out to big brands as well as independent's. Last time I saw Calvin Klein had a small unit. These are really tiny unit's just enough for one or two people stand inside. However, although most of them were rented out, I don't think they became as successful as the planners had hoped, because I don't see them springing up in other areas of London or other areas of the country! Or I could be wrong, and they were successful.
