Egbert H. Gold Estate, Prairie School estate in Park Township, United States

Egbert H. Gold Estate, also called Marigold Lodge, is a two-story Prairie School house on a 7.5-acre peninsula in Lake Macatawa. Its stucco walls carry horizontal bands of dark wood under a low hipped roof with brown shingles, red brick chimneys and pointed dormers. A one-story enclosed sun porch on the south side now serves as a dining room, and a service and guest wing attaches to the north facade.

Architect Thomas Eddy Tallmadge designed the estate in 1913 for Egbert H. Gold, whose father had invented the first cast-iron radiator and founded a steam heating business. The construction reflected the prosperity that the family's heating innovations had generated.

The lodge carries the name 'Marigold Lodge', created from the names of Gold's wife Margaret and daughter Mary Jayne. This naming reflects how the family marked its personal history in the property's identity.

The estate is private property, used by Herman Miller as a training center and private hotel for its customers, so it is not open to the general public. The main house serves as visitor center and hotel; the guest house, gazebo and other structures were replaced or reconstructed by Herman Miller.

Egbert Gold named the estate "Marigold" by combining the names of his wife Margaret and daughter Mary Jayne. The lodge was listed on the National Register of Historic Places in 1984, and Herman Miller bought it from Hope College in 1978.
