“Two Old Mill’s beautiful roof top amenity terrace contains a balance of spaces for relaxation, outdoor entertaining and outdoor cooking, all situated within a lush and varied green roof. The green roof contains a mix of extensive and intensive green roof areas, with some areas having as much as 1200mm of soil, and others employing only a 30mm mixed sedum mat with water retention fleece. The varied planting conditions support a diverse range of grasses, perennials, shrubs and trees. In certain areas, these diverse plantings are layered to maximize the visibility of the different plantings.”
Old World Luxury Coupled With Modern Day Must-Haves
Two Old Mill is a signature mixed-use condominium development with the objective of “Old world luxury coupled with modern day must-haves”. Located in the Old Mill neighbourhood of Toronto, bordering the Humber River, the building is surrounded by abundant green spaces, and bringing the feel of these surroundings to the building in a sustainable manner was the main goal of the project.
Two of Old Mill's beautiful rooftops contain a balance of spaces for relaxation, entertaining, and cooking, all situated within a lush and varied green roof. The installation contains a mix of extensive and intensive areas, with some areas having as much as 1200 mm of soil, and others only a 30 mm mixed sedum mat with water retention fleece.
Sustainability and ecological function are important aspects of the building. In addition to sedum varieties, the roof includes 13 different species of grasses, evergreen shrubs, deciduous evergreens, perennials and vines, the varied plantings and soil levels creating a more diverse habitat for local fauna. These diverse plantings are layered to maximize the visibility of the different roof areas. Although irrigated, water comes harvested from rainwater and the majority of the planting utilizes drought tolerant species to limit water use. Additionally, over 50 per cent of the species selected for the project are native to the area. The project met Toronto Green Development Standard Tier II and achieved LEED Gold Certification in 2016.
Judges praised the project for its varied landscape, lush and vibrant palette and ability to provide multiple benefits to this urban site.
