The Dunes Club's centerpiece is a large rambling Colonial Revival clubhouse designed by Thomas Pym Cope and built in 1939, after the first clubhouse (built 1928-29 to a design by club member Kenneth Murchison), was washed away by the New England Hurricane of 1938.

[3] Steve Sterling, the manager of the club, as well as his wife and his teenage son Erik, were inside at the time but were unharmed.

Bordering the parking lot and Narrow River, respectively, are eight asphalt tennis courts.

Adjoining the asphalt courts is the pro shop, which sells rackets, balls, and other tennis equipment to members.

A tennis pro and multiple instructors are employed each summer to offer private lessons, group clinics, and day camps for children.
