High Line is proving to be an increasingly strong magnet for developers

With the next section of the elevated Chelsea park known as the High Line poised to open next month, New York developers are gearing up numerous projects along the route in hopes of capitalizing on rising interest in the area.

The High Line has helped transform an area that remains a long walk from public transportation, offers less retail than other downtown neighborhoods, and until recently was associated with crime and industrial blight.

The second section, which is slated to open sometime in June and will run from 20th Street to 30th Street, is a less-developed area but has already attracted new construction.

Hanging sculptures designed with or without your input represent one of three options that A.R.T. offers at unusually reasonable prices.

Donald Rattner, a friend who is a successful architect, is branching out – almost literally.  He has started a business called A.R.T., which Don characterizes as “a new way to create, collect and think about contemporary art” by making high quality, original art more accessible to more people.

He and his wife Gaby opened a pop-up store in Brooklyn’s pulsating DUMBO (near Grimaldi’s impossibly popular restaurant) that I visited a few days ago, and I was blown away by the quality of the design and the level of creativity.  Best of all, the prices are within reach of many consumers.

The average price of one module ranges from $38/unit to $55/unit for the shelf art and $45 to $60 for the wall art per module, with a minimum order of two or three units, depending on the line. Mural art runs $8-10 a square foot.
