The Morse Building has two articulated facades featuring round- and segmental-arched fenestration. It is, in part, the earliest surviving tall “fireproof” New York office building of the period prior to the full development of the skyscraper. The architects employed a generally-praised stylistic combination of Victorian Gothic, neo-Grec. The building is an early example of the use of brick and terra cotta for the exterior cladding of office buildings in that period, with intricate polychrome brickwork.
