The George Washington Masonic National Memorial is Neoclassical in  style.
Portions of the building are also in the Greek Revival and Romanesque Revival styles.
The columns which form the portico, are in the first floor assembly hall and the second floor main hall, and on the first tier of the tower are Doric.
However, the columns on the second tier of the tower are Ionic, and the columns on the third tier of the tower are Corinthian.

The memorial consists of nine floors.
The first (or "ground") floor appears, from the outside, to be part of the foundation.
In the center of the first floor is the Grand Masonic Hall.
The Grand Masonic Hall features eight large green granite columns, four on each side of the hall.
The Grand Masonic Hall is 66 feet (20 m) long, 66 feet (20 m) wide, and 20 feet (6.1 m) high.
The 12 dioramas commissioned in the mid-1960s are located in this hall.
At the western end of the hall are short steps which lead up to an alcove in which a bronze bust of George Washington was placed in 2008.
The semicircular alcove surrounding the bust contains murals depicting Masonic events in the life of Washington.
For many years, the Great Seal of the United States donated by President Truman to the memorial in 1948 was displayed in this hall, but it was removed in the late 1990s.
Large, medium, and small meeting rooms are on the north and south sides of the Grand Masonic Hall.
All three rooms on the north side contain exhibits which document the history and activities of the Shriners.
Many of the models in these rooms depict Shriner charities, and one model is a miniature mechanical version of a Shriners' parade.
The medium-sized room on the memorial's southwest corner contains an exhibit about Freemasonry in general.
The medium-sized meeting room (the George Washington Room) and large-sized meeting room (the Andrew Jackson Room) on the south side are generally closed to the public but can be rented as meeting space.

The second (or "main") floor appears, from the outside, to be the main level of the memorial.
The Parthenon-inspired portico with its Doric columns forms the primary entrance to the memorial.
The portico is supported by eight fluted columns of pink Conway granite 5.92 feet (1.80 m) in diameter and 33 feet (10 m) high, each weighing 63 short tons (57 t).
The bas-relief medallion of Washington in profile which is incorporated into the pediment above the portico is 7 feet (2.1 m) across.
Bronze doors lead the way into the memorial.
Once inside the memorial, to the left is the Alexandria-Washington Lodge No.
22 Replica Lodge Room, which faithfully duplicates the look of the lodge room at the time Washington presided over the lodge.
This room contains several items which belonged to Washington as well as historic items (such as furniture) from the Alexandria-Washington Lodge.
Behind the Master Mason's chair in this room is the William Joseph Williams portrait of Washington in his Masonic garb.
Along the south side of this floor is the South Lodge Room, which replicates the Neoclassical look of the Alexandria-Washington Lodge when it was located in the Alexandria City Courthouse.
This room is used for meetings of Alexandria-Washington Lodge No.
22 as well as other Masonic lodges who wish to use it for meetings while visiting the memorial.

The main feature of the second floor is the Memorial Hall, which is 100 feet (30 m) long, 66 feet (20 m) wide, and 51 feet (16 m) high.
Eight green granite columns (four on each side) support the roof of the Memorial Hall.
Each column is 38.5 feet (11.7 m) high, 4 feet (1.2 m) wide at the base, and weighs 63 short tons (57 t).
On the western end of the hall is the 17 feet (5.2 m) high bronze statue of Washington in Masonic regalia.
It weighs 7 short tons (6.4 t).
The floor is composed of Tennessee marble in a geometric design, and the walls are of Missouri marble.
In the corners of the Memorial Hall are four 8-foot (2.4 m) high bronze lamps, donated by the Order of the Eastern Star (a Masonic social organization composed primarily of women).
