Park Slope passive house condo with quirky, monolithic facade asks from $1.5M

See what went into making this eco-friendly building come to life

A quirky Park Slope condo that stands like a shiny black monolith among red-brick neighbors has now launched sales on its three apartments. The boutique condo was built to Passive House standards, and if that isn't evident from taking one look at the four-story structure's facade, here are some details that will illuminate it further.

What appear to be black windows on the building's southern facade are in fact solar panels or as the developer officially describes it, "high efficiency black-on-black solar array." The facade also features reclaimed Ipe, a Brazilian walnut that was milled from boardwalks destroyed during Hurricane Sandy. The building's windows are triple glazed to better regulate temperature and sound.

Inside, the apartments have reclaimed heart pine wood floors that were milled from beams within the former Domino sugar factory, structural beams from a building across the street that were used to create built-in shelves and staircases, and LED lighting that uses 80 percent less energy than an incandescent bulb.

The three apartments in the building are a garden-level triplex with a two-level garden, a full-floor two-bedroom with a balcony, and a triplex penthouse with a private roof deck. The apartments are asking $2.795 million, $1.495 million, and $2.995 million respectively, and Corcoran's Behzad Amiri is handling sales.
