The following is an architectural description of 5 St Josephs Terrace, as printed in the Building Structure Inventory Report, issued by the New York State Historic Trust, Office of Parks and Recreation, August 1974.
This massive brownstone with basement has a monumental entry step treatment that leads to a stone semi-circular arched doorway with keystone. The entrance itself has a single wooden door, sidelights, and transom. Stringcourses occur at all floors, and a double window and under-step entry appear at ground level. The large first-floor window has a semi-circular arched transom and a stone header with keystone. The second floor window treatment includes: a wooden oriel window with organically detailed stone base, three single double hung 1/1 windows with stained glass transoms, and a dentilated cornice; and a single double hung 1/1 window with a semi-circular arched stained glass transom (all of which is framed in stone.) Small buttress-like elements divide the massive roof cornice into two bays. The right bay has a paneled frieze with roundel eyebrow window and parapet. The left bay also has a paneled frieze with an ornately detailed roundel eyebrow window with keystone and parapet.
