While we carefully restored this majestic Park Slope limestone row house, the new insertions were sleekly modern. This high contrast shows in details like the cast glass globes hung over the ornate wood stair.

We used soapstone not only for the kitchen counters, but also for the baseboards and floor border. And a mod-stained glass door lightens the heavy wood wainscot of a traditional dining room. Downstairs, an oversized aquarium gives the TV room an under-water vibe. And out of doors, we sculpted the garden and rooftop into open-air rooms for dining and lounging.
