The problem is that most condo buyers are investors who rent out the units. They don't care about how the building looks.
I would be interested to hear what percentage of condos are purchased by those who will actually live in the units, as opposed to investors. Anybody with that info?
I can't comment on the viewpoint of the investors, but when my wife and I bought our unit, there were a number of factors involved, all of which had to be juggled. As I recall, the order of importance was:
1. It had to be in the price range we could afford.
2. Location and quality of the neighbourhood.
3. Internal space, layout, fit and finish
4. Reputation of the management of the building. We didn't want to get into a building with a history of trouble.
5. View from the unit. (We do live in Vancouver where that may be a bigger consideration than some places.)
6. Building amenities
7. The external appearance of the building, ie. is it architecturally striking or at least competent.
That is, even for a person like myself with a longtime interest in architecture,, the appearance of the building from the outside was well down the priority list. In short, if we are talking about appearance, the inside is more important than the outside. Now, it doesn't mean that I ignored this factor, just that it wasn't one of the main things. It also functioned chiefly as a negative factor. If it was really hideous, I wouldn't want to buy. For example, I wouldn't want to buy in the Fred Flintstone Condo in Toronto because I would get so tired of guests laughing at the entrance to the building. But once past a certain threshold. external appearance was not a deciding factor between buildings I otherwise liked.
I think it is possible that our reasoning process and our set of priorities would be common. By contrast, here on UT, the external appearance of a building is, understandably, a primary consideration.
