Welcome to 420 West Allens Lane, a historic treasure nestled in coveted West Mount Airy. This meticulously renovated 5 bedroom, 3.5 bath late 19th-century farmhouse, accompanied by a picturesque 2-bedroom stone carriage house and immaculate grounds, situated on two lots comprising almost half an acre, offers an unparalleled oasis within the city. This home is ideal for multi-generational living, working from home, or simply a stunning hideaway. Enter the main house through the glass-paned vestibule to a formal living room, boasting large windows, built-in bookshelves, original hardwood floors, and a fantastic fireplace that serves as the room's focal point. Adjacent to the living room is a spacious dining room, perfect for memorable gatherings. It is complemented by a butler's pantry with wet bar, beverage refrigerator, granite countertops, and stylish built-in cabinets. The eat-in chef's kitchen, equipped with stainless appliances, Smeg range and underfloor heating, is a light-filled, happy space with a convenient laundry area and powder room, while the rear-entry mudroom adds practicality. A bright sunroom with views across the lawn and a second fireplace completes the first level. The second floor, accessed by front and rear staircases, offers three bedrooms, including one currently configured as a suite with dressing room and en-suite bathroom and another with an adjacent sitting room and full bathroom. Venturing to the third floor, you will find two more bedrooms with views across West Mt. Airy,  and a beautiful, sunny bathroom with dual vanities, a soaking tub, and a separate walk-in shower. The historic carriage house, featuring vaulted wood beam ceilings, a wood burning fireplace, and a deck overlooking the grounds, adds uniqueness to this property. With two bedrooms, a galley kitchen, and a full bath, it provides an ideal space for guests, in-laws, a studio, office or use for rental income (after retaining a rental license).  Below, there is a three-car garage with two EV chargers and abundant storage. Beautifully landscaped and fully fenced, the garden offers both aesthetic beauty and practical space for gardening, playing, entertaining, and relaxation. There's even a chicken coop (now being used as a shed)! Freshly painted exterior; newer roofing; privacy fence; new chimney flues and EPA certified wood burning insert; and updated wiring and plumbing are all great advantages. The location offers easy access to the city, and the convenience of walking to dining, shopping, Fairmount Park trails and public transit in both Mount Airy and Chestnut Hill. This timeless home, full of historical charm and contemporary comforts, is sure to appeal. Update: Seller has retained a zoning attorney with the goal of securing zoning relief for single home development on 422 W Allens, as well as recording two separate deeds for 420 and 422. Both parcels are still being sold together.
