One-of-a-kind penthouse at Baker Square, this stunning two-story corner residence combines historic charm with thoughtfully updated living. Exposed brick, oversized plantation-shuttered windows, and an open-concept kitchen, dining, and living area create a warm and inviting first floor filled with natural light. The main level also features a spacious primary suite with en-suite bath, a second bedroom and full bath, plus in-unit laundry for everyday convenience.A graceful turned staircase off the living room leads to the second-floor den, highlighted by a dramatic five-foot ceiling atrium. Just a few steps beyond, French doors open to PM309’s private rooftop deck and garden—approximately 400 square feet and the only private roof deck at Baker Square. Beautifully enclosed with Walpole fencing, the rooftop retreat offers granite pavers, double electrical outlets for grilling and entertaining, and a lush garden of potted trees and plantings maintained with an irrigation system.
