101 Upper Prince Street is a wood framed Craftsman Bungalow set close to the street on a treed lot. It features a low pitched roof, front verandah, and exposed rafter ends. Located among a number of heritage houses, it was part of an exclusive neighbourhood that was at one time named Haviland Lane for the prominent Haviland family who owned a great deal of property in the area. The name of the street was later changed to Upper Prince Street. The designation encompasses the building's exterior and parcel; it does not include the building's interior.
