19th century townhouse gets dreamy LEED-certified reno (with its own elevator)

<p /> Everything old is new again at <a href="http://www.corcoran.com/nyc/Listings/Display/3883394">4 Bedford St.</a> The 4,432-square-foot West Village townhouse was originally constructed as a three-story home in 1829, before it sprouted a fourth level about half a decade later. It's been through several changes in the years since, most notably a gut renovation in 2014. Today, the stately Federal-era facade belies a polished, decidedly 21st century interior, completely with state-of-the-art appliances, a <a href="http://inhabitat.com/our-top-picks-from-noho-design-district-2012/lindsay-adelman-sonos-speakers/">Sonos</a> audio system, motorized window treatments, one-touch air-conditioning, and video intercom panels on every floor. High-speed Internet is a given, of course. And if stairs prove to be a chore, you can zip from floor to floor in your very own elevator.

<p /> Thanks to the efforts of real-estate developer <a href="http://dyalcompass.com/">Candace Dyal</a>, 4 Bedford has its green bonafides, as well.

<p /> The property boasts LEED Gold certification for features such as its green rooftop, which was "designed to maximize eco-friendly possibilities with its ability to retain rainwater, and improve energy efficiency and air quality," according to its listing.

<p /> Other details include an open-plan kitchen, a deck and garden, a multipurpose recreation room, bedrooms with en-suite baths, and capacious his-and-her walk-in closets.

<p /> The look is thoroughly modern: an amalgamation of hardwood, brushed steel, and white marble.

<p /> "Setting the new standard in eco-friendly townhouse living, 4 Bedford is a rare and unique residence located in the sought-after Greenwich Village Historic District II," the listing continues.

<p /> None of this comes cheap, of course.

<p /> Just blocks away from Washington Square Park, the well-appointed home will run you about $12.5 million in change.

<p /> The building comes with 5 bedrooms and 6.5 bathrooms.

<p /> A large great room leads into the living and dining areas.

<p /> The rooftop deck offers ample room for entertaining.

<p /> Corcoran calls the green rooftop the building's "pièce de résistance."

<p /> Piqued your interest? <a href="http://www.corcoran.com/nyc/Listings/Display/3883394">Corcoran</a> is holding an open house between 2:30 p.m. and 4 p.m. on February 12.
