Grand double doors reveal the inviting front parlor topped by soaring 11-foot ceilings. A stately fireplace anchors the space, and extra-tall windows feature ornately carved enframements and the original shutters that can be found on all street-facing exposures. A shouldered archway adds grandeur while concealed pocket doors reveal a dramatic library surrounded by built-in cabinetry, a fireplace, an authentic pier mirror and lush backyard views. An adjacent study is the perfect spacious and bright home office. On the garden level, the formal dining room welcomes gracious gatherings with its generous footprint, gorgeous wainscoting, built-in buffet and fireplace. The adjacent butler's pantry aids in effortless entertaining, and the sprawling eat-in kitchen is filled with extraordinary southern sunlight. Painted tin ceilings, exposed brick and the original wood-burning stove nod to the home's historic origins while the large pantry adds convenience for busy modern households. Outside, the delightful garden creates a tranquil urban oasis for al fresco dining and lounging under the canopy of a giant maple tree. Inside, a powder room, closets and laundry complete the lower level. Head to the home's skylit top floor to discover serene private quarters.
