From this interesting link , where different projects are ranked, I discovered that the Design is from Takenaka corporation. It is named also a cooperation with the McCartney store planning Office for the interior. They were wise enough to accept a Japanase firm to sing their exterior.
The dseignof Takenaka might be a spin off of their previous creative successes, but it still playing well with such wild antagonists (Miu Miu and Prada, read Herzog & De Meuron-)
From the web, it seems during nights it even looks more interesting that during daytime.
IN the same day where we enjoyed the new store of Miu Miu, we discovered many stores that has british brands, taht were not there before. I guess it was a positive effect of the London Olympics, and in general of the increased access to English Schools all over the country. Aoyama is the end of Omotesando, so it is quite the same neigbourhour but it has some up class notes here and there. Like for instance if you, one day want to buy a Bugatti, you have to go up there.
Or there is a Noh Theatre space just few steps from this McCartney store. It has performances only once every month on fridays evenings….so there is also the jazz club, called Blue Note if I am not mistaking the name….and so and so…
