The great blog http://influxinsights.com/ recently wrote about a tiny coffee shop in New York that is differentiating them from big corporate competitors by using architecture as the main tool.
Few big retailers have really seized the potential of a profound belief in architecture.
Of course some fashion retailers have impressing flagship architecture and also Apple have grasped the potential. But I guess many more ordinary and non-lifestyle chic brands could get their uniqueness from this. Maybe even a funny building for a Toy-store could work.
