What do you do when your terrace backs up to Manhattan's most popular public space? Well, if you're a person with a normal desire for privacy, you build a fence, or at the very least plant some tall bushes. If you're gallerist Marianne Boesky, you have your landscape designer construct a 16-foot-wide buffer out of organic, dynamic driftwood. The L-shaped terrace of Boesky's coveted Chelsea apartment (which I featured way back in 2007) sits five feet from the High Line, a planted pedestrian walkway along the former elevated freight railroad of the West Side Line, which reopened as a park in June. I imagine many homeowners might head straight to the picket line upon learning that their private space would become public. Boesky, on the other hand, headed straight for design. Her solution is beautiful, don't you think?
