In case there was any doubt about how dramatically the Brooklyn skyline's changed since the mid-aughts, these ten before-and-after images of towers constructed over the past decade are here to clear that up. Compiled by RentCafé, a sister site to Point2Homes which brought us a whole other group of stunning before-and-afters, the images primarily focus on the transformation of Downtown Brooklyn, an area still in major flux, as well as Williamsburg, which, well, forget it.

↑ It's hard to believe that just eight years ago the Williamsburg waterfront area that would give rise to some of the most consistently complained about buildingsThe Edge I and II, Two Northside Piers, and 1 North 4th Placewas mostly a big patch of dirt.

↑ Need proof that development happens at hyper-speed in New York City? Here's another view of the Williamsburg waterfront, looking towards 1 and 2 Northside Piers and The Edge I.

↑ It looks like this Downtown Brooklyn building grew a long and lean glass tumor that goes by the name of 388 Bridge Street.

↑ Although he can't seem to sink the mayorship, John Catsimatidis has one thing (other than grocery stores) going for him. He's also a developer, and is responsible for this 15-story building on Myrtle Avenue at Fleet Place in Fort Greene, called The Giovanni.

↑ Downtown Brooklyn's been experiencing a building boom and has, since 2009, been graced with giant apartment buildings like BKLYN Air (nee Oro 2) and Avalon Fort Greene.

↑ Two hotels, a Sheraton and an Aloft, have sprung up on Duffield Street between Metrotech and Fulton in Downtown Brooklyn since 2007.

↑ Since 2007, a 25-story building's grown on Downtown Brooklyn's Livingston Street.

↑ Two new developments, Avalon Fort Greene and Toren, have brought 871 apartments to Myrtle Avenue in Downtown Brooklyn since 2007.

↑ 66 Rockwell in Downtown Brooklyn shot up 42 stories since 2007.

↑ A 17-story rental building's sprung up at 163 Washington Avenue in Clinton Hill.
