Hart Senate Office Building

The Hart Senate Office Building is a federal structure on Capitol Hill in Washington DC with nine floors covered in white Vermont marble and large glass surfaces. The rooms spread across several corridors arranged around a central courtyard that receives daylight from above.

Construction lasted from January 1975 to November 1982 and served to expand working spaces for the Senate. The structure received its name after a Michigan senator who served for 18 years in office.

The building takes its name from a senator whose office was previously located in another part of Capitol Hill. Visitors often see staff and elected officials moving between meeting rooms and their workspaces.

The structure connects through an underground rail system to other congressional buildings, intended for government staff. Visitors should note that access may be limited depending on security conditions and ongoing events.

The atrium is covered by a skylight made of 18 adjacent ceiling windows, each containing nine separate panels. This design allows natural light to reach deep into the interior spaces and changes the mood depending on the time of day.
