The 180 Wellington project takes an insurance company office building, originally built in 1927 and expanded in 1959, replaces and upgrades the mechanical, electrical systems and seismic capacity and transforms it into swing space for the Government of Canada House of Commons. The Beaux Arts building shell and the few remaining character defining heritage rooms on the ground floor are preserved, restored and used as the inspiration for the interior design of the rest of the complex. The original 1927 heritage entry access is developed as the private entry for Members of Parliament while the 1959 entry is reconstructed and transformed into an entry for the public. In order to provide access to the upper level Multi-purpose rooms a new public space system has been developed that includes a 2 storey ground floor atrium with a green wall, spiral stair and a 3 storey escalator all located in the heart of the building recreating a light well that was previously in that location. The public circulation extends up to the 3rd and 4th floors where the public space is organized in response to the ground floor beaux arts organization and aligning with the exterior heritage façade fenestration and pilaster pattern, The result features crush spaces, located along the exterior walls with views of the Corinthian column capitals of the heritage façade as well as Parliament Hill and the surrounding cityscape, supporting the wood clad multi-purpose rooms. The culmination of the grand space system is the satellite Library of Parliament facility a two storey space with a skylight above. The walls consist of acoustical wood panels below with sculptural copper shells in front of a perforated copper acoustic wall backing above all constructed from copper recycled from the historic 1927 roof that was replaced as part of the project.
