Located in the trendy DUMBO (down under the Manhattan bridge overpass) neighbourhood of Brooklyn, New York is One Main Street; a 126-unit loft conversion by David Walentas (creator of the DUMBO neighbourhood) in 1998. The former cardboard box factory was originally built in 1915 and features a beautiful clock tower.

Walentas renamed it the Clocktower Building with the pièce de résistance being a 3-floor penthouse spanning over 6,813 square feet (633 sq. m) and defined by four 14-ft glass clocks on every wall. The three bedroom, 3.5 bathroom penthouse offers 360-degree views, soaring 16-50 ft ceilings, a glass-enclosed private elevator and a skyroof cabana and open deck.

The property was first listed in 2009 for a cool $25 million but has remained unsold on the market, unable to find a buyer willing to purchase what would be the most expensive property ever bought in Brooklyn. In 2011 the property was re-listed for $23.5 million and was also offered as a $50,000/month rental.

In 2012 the list price was again dropped to $19 million but no suitors were found. This year, Corcoran Group Real Estate is handling the listing with an asking price of $18 million. If you or anyone you know might be interested, feel free to contact them direct.
