Over the past three years, a series of high-rise developments have rewritten the Downtown Los Angeles skyline.  No better evidence is needed than the before-and-after images displayed below.

Architectural photographer Hunter Kerhart snapped the first image from a helicopter in February 2014, at a time when the 1,100-foot tall Wilshire Grand was little more than a hole in the ground and the four-tower Metropolis development had yet to break ground.

Fast forward to December 2016, and a follow-up image from Kerhart shows both projects nearing completion, with guest appearances fron Onni's LEVEL and 820 Olive Street.

More changes to the skyline may also be on the horizon: plans emerged last month for a trio of proposed high-rise buildings flanking the Harbor Freeway.

Studio Gang-Designed Tower Proposed in Chinatown

The 26-story building would rise at 643 N. Spring Street.

A curving mixed-use tower designed by Studio Gang is set to rise in Chinatown.

The project, first reported by Curbed, calls for replacing a series of small commercial at 643 N. Spring Street with a 26-story, 270-foot-tall building that would feature 300 apartments, 149 hotel rooms, and public open space.
