The secluded, 50-plus-acre property at 1543 Monk Rd., with its 14,000-square-foot, 20-room Norman-style manor house, formal gardens, orchards, two heated pools, pool house, and tennis court, has been owned since 1999 by Robert L. Burch, a venture capitalist and, with his brother, J. Christopher Burch, cofounder of Eagle Eye, a retailer of outdoors sportswear they sold the same year.
Robert Burch is chief executive officer of UgMO Technologies of King of Prussia, which develops irrigation systems. He declined to be interviewed.
The property listing was activated Monday in time for the start of this week’s U.S. Open at Merion Golf Club. John C. Dubbs and Eleanor Morsbach Godin, of Prudential Fox & Roach in Malvern, believe the tournament will give the residence national exposure.
