When news broke out that a high profile condo tower at the intersection of Yonge and Bloor in Toronto would not be constructed, suggestions began popping up for public space alternatives. Being one of the most valuable pieces of property in the city has made the idea of it becoming solely a public square somewhat unlikely. Architecture critic Christopher Hume suggested the possibility of a public private venture, which led me to envision a vertical park for the site that would be attached to a mixed use residential tower. The main feature of the design is a one mile, gently curving gradient that winds its way up to a height of 66 metres, affording panoramic vistas of the downtown. The structure would make use of its southern exposure for passive solar heating, allowing the green space to be enjoyed year round with minimal energy expenditure. I created the model using Google’s free SketchUp software, it can be downloaded from the 3D warehouse and viewed in Google Earth (to hide the former buildings at the site simply right click on them).
