The
short form and long form heritage reports don't really say why the curved elevator lobby is protected. Maybe it's just an example of a unique form, not necessarily construction materials or elements.
The full list of elements that require approval prior to alteration include:
Exterior
1. Limestone clad, six-storey structure filling the north portion of the block on Portage Avenue between Memorial Boulevard and Vaughan Street, its three main facades facing west (Memorial Boulevard), east (Vaughan Street) and north (Portage Avenue) and its rear facade partially hidden by a parkade.
2. Canopy running along the east, west and north facades.
3. Metal base of beacon on roof.
4. Its main floors with large display windows protected by a canopy, rounded northwest and northeast corners, five bronze framed entrances, upper floors with bays created by unfluted pilasters with Corinthian capitals, windows on all levels in rectilinear openings, cornice between fifth and sixth floors and parapet with balustrade.
Interior
1. Examples of reinforced concrete structural system.
2. Examples of the curved elevator lobby.
