Classic brownstones are what's selling in Brooklyn these days, and that was what Gary and Jessica Pollard were looking for in 2006. Instead, they ended up with 305 Degraw Street, a 25-foot-wide, 60-foot-deep brick townhouse, hired architect Michael Ingui of Baxt Ingui Architects to give it an extremely modern renovation, and have now put back on the market for $8 million. The house, which the Pollards paid $1.875 million for, was just featured in the Times, and includes, most notably, an 18' x 10' wall of nine species of plants that runs up the first two stories, with an automatic irrigation system feeding it from the basement. Other highlights include a garage, a finished basement with media room, an elevator, and an all-glass rear facade. In short, this is a very, very cool renovation. It's also by far the most expensive single-family townhouse ever listed in Cobble Hill. 233 Warren Street, a few blocks north, set a neighborhood record in November when it sold for a hair over $6 million.
