Looks like work is beginning on Promenade on Robie Street in Halifax. They are demolishing some houses and moving others around to make room for the towers. It will be two towers, 31 storeys and 30 storeys.
Halifax will go from having a 33 storey tower for 50 years to having 4 under construction with maybe some more to come. There is a triple 30 storey proposal in Dartmouth and there are a few others. It seems that 30 storeys is the standard economical tower height in the city now and is allowed in a few different planning areas. The tallest approved tower is I think 36 floors (120 m) but it's in a multi-phase pipeline and may not be built anytime soon.
A lot of the planning areas in Halifax have seemingly arbitrary height limits. And they have FAR limits too. I think there is a kind of titillation that the NIMBY groups get from arguing about how much society should be allowed to give in to the moral deprivation of the evil developers. Kind of like discussions of censorship of movies. Maybe they should install some fainting couches in the public meeting halls when they do in person sessions again in 2037.
