Mayfair West: Sustainability

At Mayfair West, we plan to deliver 17 buildings ranging in size from 4 to 26 storeys, providing over 1,600 homes to be built out in phases over approximately ten years. This includes a mix of homes for sale and rent that will cater to various income levels. Specifically, the development will feature 330 social housing units and 45 moderate-income rental housing units as well as a new 69-space childcare facility, a two-acre public park and improvements to local pedestrian and cycling infrastructure.  

Grosvenor's 2030 Net Zero Carbon Buildings Commitment (WGBC)

Mayfair West will meet Grosvenor's 2030 Commitment to achieve Net Zero Operational Carbon, utilizing the region’s renewable, hydroelectric energy source to power all homes, resulting in 1,600+ carbon-free homes across the development. In addition, the 330 units of social housing are going further, being designed to LEED Gold and Passive House standards.
