Mezzanine (2025), is a 3D digital animation inspired by three unidentified photographs Hubbard / Birchler discovered in the Baldessari files at the Nova Scotia College of Art and Design University Archives. The work reconstructs NSCAD’s now-demolished Coburg Road campus, in mid-April 1971, when two exhibitions overlapped in uncanny proximity: the final day of Baldessari’s Punishment Piece upstairs and a soon-to-open display of radio-controlled model airplanes downstairs. Hubbard / Birchler’s speculative reconstruction moves between day and night, inside and outside, staging an encounter between these unlikely neighbors —the procedural rigor of conceptual art above and the devoted enthusiasm of amateur craft below.
