After years of threats to Toronto's iconic Cube House, the beloved structure's long-feared end could be just around the corner. The beloved geometric house at 1 Sumach Street, modelled after similar cube structures in Rotterdam and constructed in 1996, has also been the subject of community-led campaigns to spare it from redevelopment. The west tower will feature the exteriors of two existing 19th-century semi-detached homes incorporated into its base. The current plan is not the first for this site, and comes just shy of four years after another high-rise was proposed in 2021 to do away with the Cube House. Block Developments acquired the site from previous developer Markee in 2023, sharing more details about the future of the Cube House in a press release last October.
