Homespun condo action, Carroll Gardens edition: The owners of 74 Second Place are in the process of converting their five-story, double-wide townhouse into four condo units. According to the construction crew working on the project, sales on the three-bedroom, two-bath apartments will start later this month. The landmark building dates back to the early ’20s, and since the units are going to be floor-thoughs they’ll probably each stretch a couple thousand feet. No word yet on prices. With all the massive condo developments going on in Brooklyn, it’s always interesting to hear about a small-scale conversion. Anyone out there contemplating—or in the process of undertaking—a similar project? GMAP P*Shark
