About this home

One of the last Great Estates of Greenwich, now with a new renovations. Gracing 75± pastoral acres, Old Mill Farm is a 1926 landmark designed by noted architect Charles Lewis Bowman for financier George Lewis Ohrstrom. Resting at the end of a private, formal drive, the Elizabethan-inspired Tudor manse of 15,800± SF is picturesque showcasing museum-quality details including 17th-century English paneling. The monumental Great Hall soars to a 40-ft cathedral ceiling above the minstrel's gallery, walk-in fireplace and leaded glass windows. Renowned landscape designer James Doyle has transformed the grounds with atmospheric formal gardens including a sculpted maze. Also on the grounds are a terraced pool, tennis court, greenhouse, stable, Cotswold cottage, log cabin and stream-fed pond.
