The Williamsburgh Bank tower is being renovated into hyper-expensive luxury towers so exclusive that you can’t even get into the website without registering. And, Brooklyn’s tallest building will eventually lose some of its view to Bruce Ratner-Frank Gehry City. (Nice to know that Loss of View is one of the great democratic institutions of urban life, biting both the rich, the poor and the in between in the you know what.)

So, Sunday’s Fort Green Association House Tour could be your last chance to take in the view from an upper floor of the tower, unless you happen to be in an income bracket to buy an apartment at the new One Hanson Place. (Asking price for the penthouse: a mindboggling $2.5 million. Studio are only $350K, though.)

The tour will include an upper floor of the tower, the interior of several of the neighborhoods more interesting residences and a stop at the “Fort Greene Modern” exhibition at the Irondale Center.

Tickets are $20 in advance or $25 on the day of the tour, and are available online from the Fort Greene Association or can be purchased at Lafayette and Fulton Street near BAM on Sunday.
