Mount Vernon Triangle has plenty of new office and apartment buildings, high-rise developments that have popped up in between Downtown DC and the I-395 scar that Capital Crossing is currently building over.

But the neighborhood's development has pushed east in recent years, and a pair of projects extending its K Street corridor are fast rising out of the ground. The Lydian, Phase 2 of the Quadrangle Development and The Wilkes Co.'s residential-over-retail projects between Fourth and Fifth streets on K, is getting close to topping out its concrete superstructure.

A block south, at 901 Fourth St. NW, the D.C. Bar Association is already cladding its $70M headquarters in glass. The bar expects the 100K SF building, which broke ground in June 2016, to save it as much as $30M in real estate costs over the next three decades.

The Bar bought the land for the building from Quadrangle and Wilkes, and the pair is also managing the development of the project. The two concurrent developments are expected to wrap up construction in early 2018.
