The architectural design of the Temple chambers relies heavily on strict symmetry, with one complex serving as a perfect mirror image of another. The layout of these specific chambers is mapped out by comparing them directly to the northern chambers that were already established.
In front of these structures lay an open space or pathway. While some consider the presence of this path to be self-evident [רד"ק], others detail its exact nature and size. It was either a broad open area in the outer courtyard, spanning fifty cubits wide and extending to the courtyard walls [רש"י ומצודת דוד], or a narrower, ten-cubit walkway running from east to west between the chambers and the outer fence [מלבי"ם]. Regardless of its precise width, this path looked completely identical to the one running alongside the northern chambers situated further up the mountain.
When it comes to the dimensions of the buildings themselves, opinions differ on how they relate to their northern counterparts. One approach maintains that the length and width of these chambers were exactly the same as those of the northern chambers [רש"י ומצודת דוד]. Another perspective views the dimensions as the primary difference between the two complexes. According to this view, while the inner northern chambers were rectangular, measuring one hundred by fifty cubits, these specific chambers were perfectly square, with their length exactly equaling their width [מלבי"ם וביאור שטיינזלץ].
The careful comparison to the northern chambers extends to every structural detail. The exits of both complexes shared the exact same form [מצודת דוד], featuring a narrow, one-cubit path leading out to the main walkway [מלבי"ם]. Furthermore, the building laws governing their construction, height, and overall structure [מצודת דוד], as well as their secular legal status [מלבי"ם], were completely identical to those of the upper chambers. Even the entrances matched perfectly, sharing the same number of doors [מצודת דוד] and facing the exact same northward direction [מלבי"ם].
