Intimate sleeping pods designed by Sleepbox have been installed at Dulles International Airport in Washington DC by architecture studio 3877.

Sleepbox has 16 bookable nap rooms that are available for hire for a minimum of one hour, to offers travellers a place to rest in privacy.

The 1,200-square-foot (111-square-metre) space in Washington Dulles International Airport, located post-security in the international concourse A, is filled with two rows of the bookable Sleepbox nap rooms.

The box-like units were originally designed by Arch Group, and have been installed at Dulles International Airport by local architecture studio 3877.

They are pre-fabricated with plywood and clad in white and grey veneers. The carpets are made from recycled nylon and the tiny spaces are completed with LED lighting.
