A plan of the peristyle was not available when the model was constructed. The model version therefore was designed using photos of the reconstruction of the peristyle in the Open Air Museum and the plan of the location of the four existing columns at Karnak today (Carlotti 2001: pl. 1).
Recently, scholars working at Karnak published a detailed study of the form and decoration of the peristyle (Letellier and Larché 2014). Their reconstruction suggests that the pillars on the east side of the hall (bordering the 4th Pylon) extended only four rows on each side, while those on the west side extended seven rows. A row of five pillars linked the two sides of the hall on the north end, while only two pillars extended out on the south side, leaving the path through the southern gateway clear. The reconstruction also includes the presence of four chapels within the hall, including the Calcite Shrine of Amenhotep I (Letellier and Larché 2014: pl. 7).
A simple sandstone pattern was applied to most parts of the peristyle on the model. However, photographs from Karnak of the clear remains of painted stripes on the cornice and shaft of the pillars were used to add these colored details to the model. A small section of one of the relief scenes (showing some vertical lines at the top and the base lines for the scenes at the bottom) was copied and added to the model of each pillar to act as a placeholder, marking the general location of the scenes. Since the scenes on each pillar differ, it was decided not to place one scene on the model multiple times. Readers should refer to the photos from the reconstructed pillars at the Open Air Museum for examples of the original scenes.
