The $59 million 901 K Street project by Clark Construction is a new, 250,000-sq-ft, 12-story building next to the Mount Vernon Place United Methodist Church in the East End neighborhood of Washington, D.C.

The project included a glass atrium that connected the two buildings.

A terra-cotta rain screen is used on the building’s exterior, the first major application of the material in D.C.

The project team also underpinned the existing church below grade. Clark was also working on a renovation of the church, which was built in 1850, and so the two project teams had to work together to make sure workflow was uninterrupted.
