Just a block or so away, a four-story, red brick house at 315 East 18th Street, near Second Avenue, which was owned by Mr. Mitchell and his wife, Heidi Mitchell, a freelance writer, sold for $9.35 million. The buyer used the limited liability company Life 2.0 in the transaction.
The gut-renovated Greek Revival structure, built around the turn of the last century, has 5,788 square feet, which includes six bedrooms, four full baths and two half baths, and two wood-burning fireplaces.

The Brooklyn townhouse market has been especially active, said Mr. Garfield, the broker, especially in neighborhoods like Cobble Hill and Brooklyn Heights.

A brownstone at 81 Pierrepont Street, a quick stroll from the Brooklyn Heights Promenade, was purchased by Mr. Aghazadeh for $12.5 million from the Brooklyn Home Company. It had been on the market for $14.5 million.
The fully renovated 1845 Greek Revival building, situated in the Brooklyn Heights Historic District, is five stories high, 25 feet wide and encompasses 8,250 square feet. There are six bedrooms, five full baths and three half baths, along with a wine cellar, gym and media room.
The ample outdoor space includes a 900-square-foot roof terrace with a kitchen, a 21-by-25-foot rear garden and a 25-by-9-foot terrace off the main bedroom suite on the third floor.
