Welcome to 1633 Lark Lane, a meticulously maintained and thoughtfully upgraded 4-bedroom, 3.5-bath Colonial in the award-winning Lower Merion School District. Situated on a private lot that is well over an acre, at the end of a quiet cul-de-sac next to fifty acres of preserved land, in a welcoming neighborhood, this home offers a peaceful, country-like atmosphere, all while being just minutes from the Villanova train station, Amtrak and the vibrant communities of the Main Line. Built in 1957, this spacious home seamlessly blends the character and craftsmanship of a classic home with the clean lines and contemporary updates. Every detail has been carefully maintained and enhanced using the highest quality materials, with expert guidance from professional landscapers, hardscapers and designers. A classic mix of stone and light gray siding, complemented by dark gray shutters and meticulously designed landscaping, elevates the home's curb appeal. A Belgium block driveway, lined with three stately stone columns topped with lanterns, makes for a grand entrance. Cobblestone pavers, a retaining wall, and a new portico with copper roof elevate the exterior. Dozens of acres of deed-restricted open space sit to the left, creating a peaceful oasis and ensuring privacy. Custom oversized front doors with Rocky Mountain hardware set the tone for both the formal entrance door and the mudroom door for everyday convenience. Step into the inviting foyer, where a new banister and railings enhance the home's timeless charm. The renovated kitchen combines modern elegance with functionality. White quartz countertops and a quartz slab backsplash complement the inset white cabinetry with glass door accents. A center island with prep sink and island seating is ideal for casual dining, while high-end appliances, including a Sub-Zero refrigerator, Theramador professional range, and Miele dishwasher, elevate the cooking experience. A built-in banquette with white leather upholstery and a modern chandelier create a welcoming dining space. Adjacent to the breakfast area, custom-built arched bookshelves frame the wood-paneled pantry doors. A desk area is also found here. The formal rooms on the main level offer elegance and versatility. The dining room features custom marble built-ins for showcasing fine dishware, and French doors allow natural light to flood the space. The family room and library provide panoramic views of the expansive backyard, blending indoor and outdoor living. New ceiling fixtures and sconces in the dining room add a refined touch. A powder room, also with new fixtures, and a mudroom with access to the attached two-car garage complete this level. Upstairs, the primary suite offers a luxurious retreat, complete with a spacious walk-in closet and a stunning sitting room/office with a wall of windows and very high ceilings. The primary bath has been updated with new faucets and lighting fixtures for added elegance. Three generous additional bedrooms each include built-in closets. The brand-new lower level (2025) adds versatility, featuring a bonus room with LVP floors, a dedicated exercise room with tile flooring, and a full bath. Recent upgrades include a French drain, sump pump, new windows and a Generac whole-house generator for peace of mind. A true highlight of the home is the spacious, private backyard. The design of the home ensures a seamless connection to the outdoors, with large windows offering panoramic views from the kitchen, family room, library, and sitting room. Step outside onto the expanded patio, where a built-in Viking gas grill and lush landscaping create a private oasis. The flat driveway doubles as a pickleball court, and the spacious yard offers ample room for outdoor activities. Located in a welcoming, walkable neighborhood, this one-of-a-kind Colonial offers a rare opportunity to own a thoughtfully updated, move-in-ready home in a prime Main Line location.
