To build or not to build is not always a matter of demand. There is an increasingly high number of newly accomplished buildings popping up on the real estate market of Buenos Aires. I don't want to know how many of these office and apartment buildings will stand empty after completion forming a deserted ghost town. Frankly, there are thousands of people who would and could fill these buildings with life but cannot afford it. I do know these buildings are not projected to make the world a better place, but you can't stop me from dreaming.
Apropos, this isn't a phenomenon that arises only in Argentina. Have you ever heard of the new ghost towns in Spain? Ciudad Valdeluz, for instance, is a completely newly constructed city for approx. 30,000 inhabitants, but has in fact not more than 197 after all. — And it doesn't look like it's going to get any better.
