It's a good document, and the following statements explain a lot, including how the economics of construction have changed:
Quote:
The economics of building in St. John’s are different from 5 and 10 years ago. Costs such as construction and real estate have risen rapidly. Non-economical projects won’t get done. Developments require significant floor space to be economical. In the downtown, the means to acquire floor space other than via height are limited. . .
Regarding height as a means of achieving density, the British Property Federation notes, “as it is not practical to add a few floors across many of the existing commercial buildings in a developed district, extra floor space will principally be delivered by the replacement of existing buildings with new buildings in a few selected locations.” Making “redevelopment viable usually requires a significant increase in development density, which can sometimes be attained only by building up…in basic terms, efficiently adding height (and floorspace) to a building design adds to the density provided on the same footprint. So, for example, given a planned five storey building in a key commercial district, keeping the same footprint and doubling the floors to ten floors, while maybe not doubling the floorspace, still provides considerable added commercial density.” . . .
“adding employment density can only be commercially viable by adding a few relatively tall buildings, rather than adding a few storeys across many buildings.”
