Empty the building, leave its sculptural brick enclosure exactly the way it is, and implant in it a massive heart of concrete. This was the strategy followed by Tadao Ando when he transformed an old residential block in the city of Chicago into the non-commercial exhibition space known as Wrightwood 659. Completing the revamped construction is a terrace which, crowning an atrium that rises the entire height of the building, is bound to delight visitors with the spectacular views it offers. The new art center was inaugurated in time with the opening of ‘The Challenge,’ the show currently on view at the Centre Pompidou in Paris that presents the oeuvre of the now 77-year-old Japanese master, who has already survived five organ extirpations. The exhibition might well be a good-bye.
