Welcome to 4 Stony Brook Rd., the former carriage house from the original estate in the Round Hill neighborhood (subject home was relocated by the subdivision developer, to this site in 1964+-). The current owners have enjoyed nearly 30 years. They've thoughtfully transformed this home, employing Architect John McConnell, into a shingle-style residence in 2000-2001 (including bathroom remodels in 2011), nearly doubling its original size. Open-concept family room features a dramatic vaulted ceiling w/custom windows and ceiling fan. Adjacent breakfast area overlooks the patio and expansive, lushly-landscaped yard. The primary bedroom features a separate balcony to the rear yard, w. 2 walk-in closets leading to the double-vanity bath with steam shower and whirlpool tub. There is a lower level recreation/play room w/ cedar closet, separate exercise room; massive storage areas. Oversized2 car garage.. Fantastic locale near conservation/train. Buyer should verify all information.
