Impressive and impeccably maintained 5 bedroom Colonial with sensational backyard, in the most picturesque Larchmont neighborhood that walks to all! This 1923 home has been significantly expanded and fully modernized, creating a unique layout that seamlessly merges the old with the new. A charming front porch provides an inviting entrance to the first floor – where a gracious foyer and wide front hall connects the formal living and dining rooms to an enormous chef's kitchen, family room, and a fabulous screened-in porch! The eat-in kitchen is incredibly spacious and bright, with a huge center island with cooktop and hood, top of the line appliances and a sliding glass door leading to a fantastic bluestone patio. The sun-splashed family room features vaulted ceilings and skylights with additional glass doors, and the screened-in porch is a warm weather sanctuary of true living space, with hardwood floors, skylights, and the best views of the property. The park-like, beautifully landscaped, and level backyard with mature trees and perennials is a showstopper - the ultimate play space with plenty of room for a swing set and more! Completing the first floor is a large, private guest bedroom or office space, with en-suite full bathroom. Upstairs, a palatial primary bedroom suite features vaulted ceilings, plentiful closets, and a deluxe ensuite bath with soaking tub, shower stall and vanity, plus a spiral staircase leads to unfinished bonus/storage space on an upper level. Three additional bedrooms are generously proportioned and equal in size. On the lower level, a rarely found 2-car garage is connected to a large basement with great additional storage space, plus full laundry. 17 Seton Road boasts an enviable location with a short walk to the Larchmont train station, village shops, restaurants, and Murray Avenue Elementary School!
