The previous record for the borough was an $11 million Brooklyn Heights brownstone, which sold in in 2012.
The newly listed townhouse is also in Brooklyn Heights (via Curbed).
Located on Willow Street, the 1800s-era home has been renovated with a modern kitchen and appliances, but its listing at Brown Harris Stevens says it retains its original French doors and wood-burning fireplaces.
It has six bedrooms and four and half baths, with the entire top floor of the mansion dedicated to a master suite with cathedral ceilings and exposed wood beams.
