Check out this amazing building designed by Willy Muller Architects - it's the Barcelona Flower Market. I'd be shopping for flowers every weekend if I lived in Barcelona! I like the fact that the vertical bands of colour were inspired by ariel views of flower fields.
Also on The Cool Hunter I found this Vila Sofa store in Amsterdam designed by Tjep. It looks like a cross between Interior and Set Design. Not surprisingly the brand Vila Sofa is positioned a little like IKEA where products are warehoused on site and reasonably priced. In addition to the simple use of just four colours (red, white, grey, black) I also love the clever cutouts in the facade - oh that chandelier!
