I can ask the Contractor to ask the homeowner, but that has not worked so well in the past.
I will see if he can get a answer.

This sculpture is called Karma, by Do Ho Suh. It was on exhibit in front of the Albright-Knox Art Museum in Buffalo NY in 2013; could be seen on their website at http://www.albrightknox.org/collection/collection-highlights/p:3/r:10/ when I checked today. I don't know if it is part of the museum's collection or on loan. It is a very impressive piece of art.

The artist made three of this piece. The one pictured is in the Besthoff Sculpture Garden at the New Orleans Museum of Art.
