The style – “five over one – five stories of apartments over a ground-floor ‘podium’ of parking and/or retail” – is dependent on what’s called stick construction, a method begun in 1830s boomtown Chicago. Builders can find cheap material, and cheap, non-union labor, everywhere. Alert, though: “There’s a reason why stick wasn’t the default for big apartment buildings until recently, and why these buildings are limited in height: Sticks burn.” – Bloomberg Businessweek
