Thomas Kain and his sons, Henry and John, constructed this masonry showcase as an office for the family stonecutting business circa 1912. Kain is credited with developing several Helena quarries and thus contributed greatly to local building patterns by making a variety of stone types available to builders. A staunch survivor of the 1970s Urban Renewal, this small building with its rounded granite steps, curving north wall, and elaborately carved Renaissance column reveals the superior talents of a master stonecutter.
