## Formal characteristics

Art Deco commercial buildings are identifiable by a consistent set of formal characteristics that distinguish them from both their historicist predecessors and their modernist successors. Stepped or setback massing — the building's profile narrowing toward the upper floors in a series of horizontal terraces — is the defining volumetric quality. This was in part a response to North American setback requirements (New York's 1916 Zoning Resolution required building faces to step back from the street as they rose), which Art Deco architects turned from a regulatory constraint into a compositional opportunity.

Ornament in Art Deco is geometric rather than organic: chevrons, sunbursts, stylized floral forms, eagles, and abstract representations of speed and energy, all executed in low relief rather than the deep carving of earlier classical ornament. These motifs were applied to façades in bronze, terracotta, glazed ceramic tile, and highly polished stone — materials that were novel at the time and that now distinguish Art Deco buildings as a premium category of historic commercial stock.

The interior spaces of commercial Art Deco buildings — bank lobbies, department store atria, office building entrance halls — were characterised by elaborate ceiling treatments, decorative metalwork in lift enclosures and grilles, and polished stone or terrazzo floor surfaces. These interiors were intended to project financial stability and institutional permanence to tenants and customers.

In most North American secondary cities — cities with populations between 50,000 and 500,000 — the downtown commercial fabric of the 1920s and 1930s represents the first purpose-built commercial construction of the modern era. These buildings replaced earlier frame construction, wooden storefronts, and modest brick commercial blocks from the nineteenth century. They were financed by local and national banking capital at a time when secondary markets were growing faster than primary markets, and they were built to institutional standards intended to last a century or more. Many have done exactly that.

The heritage status of Art Deco commercial buildings in secondary market downtowns is a material factor in co-location site evaluation. Buildings from this era are frequently subject to municipal heritage designation, which limits demolition and imposes conditions on exterior alteration. The designation provides certainty — a heritage-designated building will not be demolished for competing development — but may limit the intensification or conversion options that would make a site viable as a Woodfine Professional Centre or adjacent-to-Power-Centre node.
