Windows

Glass folding doors from Panoramic Doors reach nine-and-a-half feet high to open the kitchen to the courtyard. “It's such a unique feature, especially in Brooklyn,” says Slocum. “You rarely ever see that type of thing.”

The courtyard is enjoyed from multiple vantage points, including the main living spaces and an office on the main floor, as well as a second-floor hallway and bedrooms.

After: The primary bedroom occupies an area that was formerly a study and a shared bathroom. Unfinished wood windows and white oak flooring are a new addition.

The double-height wall of windows in the living room looks out on the property and was a big draw on their first walk-through.
