Baker's 17-foot high (5.2 m) bronze statue of Washington was finally unveiled on February 22, 1950.
President Truman, past Grand Master of the Grand Lodge of Missouri, dedicated the statue and delivered a major foreign policy address at its unveiling.
The same year, muralist painter Allyn Cox was hired to paint murals throughout the memorial depicting allegorical Masonic events from history as well as scenes from the life of George Washington.
The Grand Lodge of California donated the funds for these murals.
Cox also designed six stained glass windows for installation above the murals, each depicting a famous Masonic patriot (such as Benjamin Franklin and Gilbert du Motier, marquis de Lafayette).
The windows were executed and installed by stained glass artist Robert Metcalf.

In 1951, the General Grand Chapter of Royal Arch Masons agreed to fund the completion of the room on the fifth floor and dedicate it to Holy Royal Arch Masonry.
That same year, two more Metcalf windows were installed in the memorial hall, the chimes were installed on the 10th floor, and a ladder (acting as a staircase) was placed to provide access to the 10th floor from the ninth floor.
 A water tank was installed on the fifth floor (to help ensure high pressure) and plumbing extended to the eighth floor, and air conditioning placed in the second floor South Lodge Room.
 A spiral staircase was added between the third and ninth floors to provide an emergency exit.
It was also in 1951 that the Grand Lodge of Pennsylvania sponsored the completion of the memorial's sixth-floor main library.
Outside the memorial, the northwest parking lot was paved and two flagpoles placed outside the main entrance.

Work on the memorial continued in 1952, although most of the work was not finished until a year later.
 The ninth floor observation deck remained unfinished (although money had been donated to enclose it in a suicide-proof iron cage), and only two floors were open to the public.
 But the sixth floor library was dedicated on February 22, and later that year Allyn Cox's sketches for the memorial hall murals were approved.
Finally, with the second-floor auditorium nearing completion, the memorial association authorized the expenditure of funds for the Moller Organ Co. to begin design and construction of a pipe organ for this space.
By early 1953, however, the observation deck was finished and opened for use, and the second inclined elevator began to be installed.
Problems with the shaft, however, delayed its completion.
Additional internal construction was also completed at this time.
The building plans had called for two sets of stairs to descend from the second floor's memorial hall to the first floor's assembly hall.
 These stairs had never been completed, however, and the space had been used for storage for years.
 Now funds were available to build the staircases.
 In order to do so, the unfinished space beneath the main portico was turned into a storage room, and the stairs were installed.
 Contractors also resealed the exterior of the tower and the second floor roof parapet to prevent water from leaking into the memorial.
By the end of 1953, the remaining stained glass windows in the memorial hall were installed.

In 1954, the 42-rank Moller organ was installed in the main auditorium.
The $50,000 for the organ had been donated by the Grand Lodge of New Jersey in 1930.
The marble staircases between the first and second floors were also completed, and the fifth floor with its Royal Arch Masonry room was almost finished as well.
The memorial association now began reconsidering some of its plans.
It was clear now that there was no need for a "States Remembrance Room" on the fourth floor, and that the eighth floor did not have enough space to hold all the Washingtoniana in the possession of the Alexandria-Washington Lodge.
 So the association resolved to make the fourth floor a Washington museum, while leaving the eighth floor open.

Allyn Cox's mural on the south wall of the memorial hall was completed in early 1955.
