Set privately on one beautifully landscaped acre in the heart of Penn Valley, 735 Righters Mill Road is a classic 1937 stone Colonial that pairs the character and craftsmanship of an earlier era with a thoughtful expansion designed for modern living. Offering more than 5,700 finished square feet, five bedrooms and five and one half baths, the home retains many of its original architectural details, including handsome millwork, hardwood floors and three fireplaces. Significant updates and a 2009 expansion introduced a more open floor plan, vaulted ceilings and generously scaled spaces for both everyday living and entertaining. At the center of the home is a beautifully appointed kitchen with a large center island and adjacent butler's pantry, opening naturally to the surrounding living spaces. A formal dining room provides an elegant setting for more traditional entertaining, while the screened porch overlooking the gardens offers an inviting place for relaxed dining, reading or simply enjoying the landscape through much of the year. Additional gathering spaces include a billiards and bar area, while two separate offices offer welcome flexibility for working from home. Two primary suites, one on the first floor and another on the second, provide unusual versatility for changing needs, extended family or guests. A separate rear staircase leads to a private guest suite, further enhancing the home's thoughtful and highly adaptable floor plan. The grounds are an exceptional complement to the architecture. Mature specimen trees and plantings, continuously blooming perennials and two water features create an arboretum-like setting that feels established, private and remarkably serene. An irrigation system helps maintain the extensive gardens, while thoughtfully placed landscape lighting transforms the property after dark. Fenced rear and side yards add another layer of privacy, and the home's position on the property creates a welcome sense of separation from both the road and neighboring residences. Remarkably convenient yet quietly removed, the property is close to Main Line schools, parks, playgrounds, the library and community pool, as well as shopping, dining and transportation. Center City Philadelphia is within easy reach. With its enduring stone architecture, gracious proportions, flexible living spaces and beautifully cultivated grounds, 735 Righters Mill Road offers the increasingly rare combination of Main Line character, privacy and ease of living.
