- Railroad turntable feature at north west corner of the building footprint spanning within the building footprint and outside of the building footprint (original built heritage and archaeological feature)
- Reinforced concrete structural frame (The 2019 work clads the concrete with limestone to retain similar historical forms and proportions.)
- Asymmetrical massing with three bays on east end and six on the west end, with recessed bay on the south side of the building
- Five storey tower on the southwest corner of the building with additional unenclosed "sixth" storey (feature of 1912 construction)
- Otherwise generally uniform rhythm of bays on sides
- Articulated brick parapet wall
- Tripartite glazing system (The original eastern portion of the building had six over six double hung sash windows in sets of three. The western portion of the building had a similar tripartite sash, but with each third composed of 16 to 20 fixed panes, with the exception of the center panels. The center panels consist of a center pivot 6 panel casement windows. The 2019 redevelopment includes a prefinished aluminum tripartite glazing system on the majority of upper floors, thus replicating the appearance of the c.1911 glazing.)
- Brick infill spandrel panels within bays beneath the tripartite glazing system
- Brick pillars on the east side of the property
