If you didn't know, there is actually a reason the buildings are soo short in DC... Check this article from the Post to understand:
"There’s new momentum to relax federal building-height limits in the District, reopening decades-old debates about the look, feel and character of the city as well as whether the restrictions stifle economic growth.
Mayor Vincent C. Gray (D) has spoken with U.S. Rep. Darrell Issa (R-Calif.) and Del. Eleanor Holmes Norton (D) in recent weeks about ways Congress could amend height regulations that limit most city buildings to 130 feet.
Unlike other major cities known for their skylines punctuated by iconic skyscrapers, the District is dotted by low-rises and federally protected monuments. Developers have repeatedly said the rules have led to a squatty, boxy look along major commercial corridors, such as K Street and Connecticut Avenue."
