Designing for experience: Inside the Atrium and the Great Library

Osgoode Hall’s interiors convey a sense of institutional authority, evident in the Atrium’s grandeur and the Great Library’s extravagant ornamentation, which characterize these spaces.

Creating the Atrium

While one of the reasons for removing the original dome might have been to cut costs, the reconstruction of the central Atrium was so magnificent that it counteracted any financial savings. Additionally, the grand scale of this entrance reflects the evolution of Ontario’s highest courts. Although this large open area offers little in terms of functionality, it maximizes the “architectural experience” at the heart of the building.

Architecture for experience

The Atrium was designed as the building’s monumental core, drawing its stylistic inspiration from the Italian Renaissance palazzo, such as the Palazzo Tursi Doria in Genoa designed by Rocco Lurago in 1564. Here, the architects specified a vibrant floor of multi-colored tessellated tiles manufactured by the British firm Maw & Co. At the centre of the atrium, a large, shallow central dome serves as the primary light source. While the vibrant red, yellow and blue glass panels are likely original features of the building’s mid-19th century design, the stained glass has undergone subtle modifications over time. The pink glass seen today is a 1960s addition, introduced to replace the original etched glass. The original mid-1850s design used etched glass — similar to that in the Great Library — allowing a soft, uniform natural light to filter into the heart of the building.

The Great Library

Stretching 34 metres (112 feet) across the centre of the building, the Great Library was designed as a monumental interior of exceptional scale. The interior is organized into three cubes, using Palladian principles of cube rooms — a classical method for achieving spatial harmony through the repetition of mathematical modules. While the room’s length is 34 metres (112 feet), the architects used 12-metre (40-foot) proportions for its height and width to create a balanced environment. By grounding the design in these principles, Cumberland and Storm projected a sense of order and intellectual balance that reflects the foundational principles of the legal profession. In addition, the Great Library is further elevated by grand Corinthian columns set on high plinths, featuring extravagant acanthus leaves, which add to the sense of grandeur.

This architectural drawing shows a section of the library, featuring the seven arched windows, which are significantly larger than the windows on the ground floor. The vaulted dome ceiling is also depicted, helping to emphasize the Great Library’s importance as a space within Osgoode Hall.

While primarily for legal study, the library’s central area also had various other functions — including accommodating diners and dancers during special events, most notably during the 1860 visit of the Prince of Wales.
