Three Fields

Three Fields in the Borough of Mendham was home of our 20th Mansion in May and raised $1.65 Million for the new Institute of Bioskills Training and Innovation at Morristown Medical Center.

Three Fields was designed and built between 1928 and 1930 for Benjamin Duncan Mosser and his wife, the former Florence Willets Mosford. The design of the two principal buildings at Three Fields, both beautifully situated in the natural contours of the pastoral, rolling land, were described in Architecture magazine in the early 1930’s as being “in the French style,” to evoke the feeling of a long-established, rambling Norman-style country farmhouse, rustic and yet also somewhat formal in style.

Donated by Andrew Fletcher to the Borough of Mendham, the Borough decided to sell Three Fields. The proceeds from the sale were placed in a borough account called the “Andrew Fletcher Three Fields Memorial Trust Fund.” Funds have been used for the Andrew Fletcher Gazebo in Borough Park, construction of a new police department building, improvements to athletic fields, the rehabilitation of Phoenix House and renovation of its adjacent garden (maintained by the Mendham Garden Club), and the purchase of open space, including the Thomas Tract jointly owned by the borough and the Schiff Natural Lands Trust.
