The exterior of the G. G. Galloway House is asymmetrically arranged. Rectangular cut wood shingles are the primary sheathing material. Projecting side bays and oriels are covered in stuccoed pebble dash set within rectangular wood frames. Ornamental gable end brackets and exposed rafters are typical of the Bungalow style. Exterior openings are placed within plain surrounds with a crown molded lintel.
Windows have a molded sill.
Tripartite segmental arched windows ornament the east and rear elevations. A series of casement windows, each with geometric lights, are centrally placed in the end gables of the sides and rear. The foundation is of brick, arranged in common bond . Asphalt shingle is the primary roofing material. A hip roof porch dominates the front elevation, wraps around the east side to a projecting ell and terminates in a port-cochere on the west.
