McCall Development specializes in building homes and developing neighborhoods using sustainable practices. McCall Development was one of the first homebuilders in Montana, and the first in Billings, to build a certified ENERGY STAR home. What does this mean? ENERGY STAR homes are built to perform 30% more efficient than the typical new home today and substantially better than an older home. McCall’s vision is to build homes that embody the charm and character that is important to home owners today, where bigger is not always better, and affordable does not have to mean cheap.
