A former West Village firehouse at 78 Morton St., which was later converted into a grand townhouse, has just entered contract for close to its $21.8 million asking price.

“It’s a self-sustaining home, at a time when people may be shying away from shared spaces like garages and gyms at condo and co-op buildings,” says Christopher Riccio, a broker at Leslie J. Garfield, who shares the listing with Matthew Pravda and Elana Zinoman.

The soon-to-be owner and final price paid are not yet known.

Built in 1864, the renovated 25-foot-wide home is 7,281 square feet, and comes with three bedrooms, four bathrooms and two powder rooms. And thanks to its previous firehouse use, there’s also a garage with space for four cars — a rarity in the city — and an excavated cellar.

Fun details include a gym, a sauna, a wine room and an entertainment lounge with a pool table. The home also has a hidden office, up to 27-foot ceiling heights, and a wood-burning fireplace.

Design details show the home’s firehouse history, from framed payroll records and local neighborhood advertisements to the firehouse’s original spiral staircase.
