The National Building Museum's latest block party installation is a sprawling “Lawn” that channels the spirit of summer.

The view from the back of the grand hall shows the scale of the project.

The National Building Museum in Washington, DC,  is literally rolling out the green carpet for Lawn—a brand new installation that, according to their website, will “allow guests to unwind with quintessential summer activities while connecting to the design of the museum.”

Set against the museum’s great hall, the grassy, inclined expanse features communal lounging areas complete with hammocks that hang from the building’s 100-foot-tall ceilings. As you sway in summer’s bliss, speakers hidden in the hammocks play programmed audio from prominent American storytellers. 

Lawn officially opens on the Fourth of July, 2019.

In the past, the National Building Museum has transformed its great hall into a hive, a snowy expanse of icebergs, a beach, and a giant maze. The museum’s latest installation was designed in collaboration with the LAB at Rockwell Group.

Attendees can sip refreshments while playing typical turf games—like bocce ball, croquet, or cornhole. Designed by SynLawn, the fully recyclable faux-sod surface is a smart composite of soybeans and sugarcane. Adults and kids alike can also play a LAB-developed, augmented-reality game wherein catchable fireflies hover in front of you. 

The finished installation features hanging hammocks, a small pool, and a projection of the sky.
