Project rendering supplied by Gravity Architecture 

This net zero ready 87-unit stacked townhouse project by ​Avalon Master Builder is located in the northwest ​community of Arbour Lake about 800 metres from ​the Crowfoot LRT Station. The project was approved in ​July of 2022 and consists of 7 individual buildings ​ranging between 10 to 16 stacked units.

The intended ​rental development represents a mix of affordability, accessibility and energy efficiency (30% less than the ​Reference Model of NBC 2019-AE) resulting in​ 70% decrease in greenhouse gas emissions compared ​to an energy code compliant development.
