Little Mill Country Club's Blue Course was designed by Garrett J. Renn, a New Jersey-based architect who worked primarily in the mid-Atlantic region during the latter half of the twentieth century. The course occupies a site in Marlton, in Burlington County, characterized by the rolling terrain and wooded landscape typical of central New Jersey. The design reflects Renn's approach to routing through existing topography and vegetation, creating a layout that integrates with the natural contours of the property rather than imposing dramatic earthwork. The course plays through a mix of mature trees and open fairways, with water hazards and strategic bunkering defining play on many holes. The routing takes advantage of elevation changes across the property, offering variety in shot-making demands from tee to green. Renn's design philosophy typically emphasized playability across a range of skill levels while maintaining challenge for accomplished golfers, a balance evident in the Blue Course's setup. Little Mill has served the Marlton community as a private club facility, with the Blue Course functioning as one of the club's primary layouts. The course has hosted regional competitions and club championships over its history. Like many regional private clubs in New Jersey, Little Mill reflects the mid-Atlantic tradition of accessible yet well-maintained golf, designed to serve members year-round in a temperate climate where the growing season supports consistent turf conditions.
