This revamp of a parlor floor in a brick Boerum Hill row house was two-fold. First, Brooklyn-based architect Alicia Balocco opened up an existing 17-foot extension on the 20’x40’ building with a bank of aluminum-framed glass doors; a new atrium-like skylight spanning almost the full width of the building lets even more sun shine in. She also improved the kitchen layout and added a bathroom with distinctive tile walls.

Then, local interior designer Julia Mack (that’s Julia in the photo, above) gave the clients, a couple with two teenage kids, the fresh and modern look they wanted. “The house didn’t have a lot of lavish detail,” Mack says. “It seemed a perfect opportunity to bring in some modern design and not feel you were turning your back on anything that was already there.” As always, Mack made a special effort to work with local suppliers in sourcing furnishings both vintage and new.
