Toronto Council Considers Regulations for Controversial Iceberg Homes

Toronto City Council is evaluating potential regulations for “iceberg homes,” a type of luxury residence that extends significantly underground. On Wednesday, the council will discuss new rules aimed at controlling the construction of these expansive basements and protecting urban trees. The proposed regulations would mandate minimum below-ground setbacks for all low-rise residential buildings and encourage the preservation of green space.

Residents of Hoggs Hollow, including Shannon Rancourt, have voiced strong opposition to iceberg homes, describing them as detrimental to the neighborhood’s character. Rancourt highlighted a recent incident where an old maple tree was removed to make way for a new home featuring a two-and-a-half storey basement, complete with a swimming pool and basketball court. “When we looked at these plans, I was like, what the hell is this?” she remarked, expressing her disbelief at the extensive underground construction.

Architect Richard Wengle, who has worked on several iceberg homes, argues that the construction methods involved are comparable to larger developments, albeit at a smaller scale. He noted that the investments for these homes can reach several million dollars and typically occur on high-value land. Wengle acknowledged that the trend has raised environmental concerns, particularly regarding tree removal, as deeper basements often leave no space for tree roots.

Rancourt’s concerns extend beyond aesthetics; she pointed out that Hoggs Hollow frequently experiences flooding, with many homes equipped with multiple sump pumps. Her group has documented incidents of mudslides due to heavy rain, emphasizing the area’s vulnerability. “We have the Don River running through us, a lot of underground tributaries. Honestly, probably a hundred years ago they shouldn’t have built in a swamp,” she stated.

Balancing Development and Environmental Concerns

The proposed regulations aim to address both the growth of the urban tree canopy and the challenges posed by iceberg homes. The planning and housing committee has already discussed various aspects of the proposal, including on-street parking and permeable soil requirements. Councillor Paula Fletcher has raised questions about the impact of these regulations on the city’s tree population, while her colleague Stephen Holyday has inquired about how the changes might affect homeowners’ ability to install swimming pools in their backyards.

The discussion has drawn attention to the increasingly complex relationship between urban development and environmental sustainability. Committee chairman Gord Perks remarked on the interconnectedness of public policy, highlighting the significance of the iceberg homes discussion in the broader context of urban planning.

Councillor Rachel Chernos Lin, who represents Rancourt’s neighborhood, emphasized the need to consider the environmental implications of iceberg homes. She expressed concern that the increase in applications for such basements could lead to more significant challenges in managing local ecosystems. “At least what we’ve seen in Ward 15 is that there has been an increase in applications for what we call iceberg basements, and those have implications that our planning bylaws didn’t really account for,” she explained.

A Controversial Trend in Urban Living

Iceberg homes have emerged as a relatively new phenomenon in Toronto, mirroring trends observed in cities like London, where local authorities have since moved to restrict the construction of large underground spaces. While Wengle maintains that these homes are often designed to blend into their surroundings, Rancourt argues that they can disrupt the visual harmony of neighborhoods.

Despite the ongoing debates, Chernos Lin does not anticipate drastic changes from the council. She hopes for a balanced approach that preserves Toronto’s tree canopy while allowing homeowners the freedom to build. “You want people to be able to build nice homes,” she stated, recognizing the complexities involved in addressing both housing needs and environmental stewardship.

As the city council prepares to vote on the proposed regulations, the outcome could shape the future of urban development in Toronto, balancing the desires of homeowners with the environmental realities of the city.
