16-storeys, to many cities, is still considered in the realm of 'low-rise'. These are most certainly
not high-rise buildings; although, I understand they may feel as though they are, relative to St. John's other buildings.
I hope these are approved, but at the same time I would prefer for the city to not spend too much energy dwelling on building heights. If St. John's is actually concerned about developing sustainably, which means committing to core infill and preventing urban sprawl, a steady pace of 10-storey proposals would do just that.
The taller you go, the higher risk you run of oversaturating your market. Given St. John's projected growth however, 16-storeys is very reasonable and you may find that the city's rate of growth would be able to handle even taller.
But one step at a time...
