Pieces of History Recently renovated by general contractor Pankow, the Heleloa Neighborhood (previously known as Hilltop) is the only remaining historic family housing neighborhood on Marine Corps Base Hawaii (MCBH) in Kaneohe. Originally constructed between 1939 and 1940, it was the base’s first cluster of officers’ housing. “The preservation and renovation of historic properties like these are an important part of a sustainable, smart growth approach for today’s military families,” says Mike Betz, Pankow, vice president, Hawaii Division. Today the neighborhood still consists of 23 senior officers homes, 21 of which are nearly identical. The other two are Facility 511 (historically the Commanding Officer’s Quarters), and Facility 515, known as the Eisenhower House and also referred to as “the Kaneohe Bay White House” for its association with former President Dwight D. Eisenhower, who stayed there after World War II. The centerpiece of the project was retrofitting the Eisenhower House to be a net-zero energy home, which, says Betz, is the first of two planned net-zero energy homes on the base. Angela Thompson of Mason Architects, Inc. served as the qualified preservation professional overseeing the project.
