According to CTP, there is a discrepancy in the number of doorways, not made any easier to correct by the new modern brick walling.
CTP said that according to the plan by Eschebach in 1969, there were six entrances marked, but his number 2 doorway was now missing behind the restored brick wall. This should now leave five entrances.
There is however written documentation that Mau and Spano described seven entrances on this south front. Then Spano mentioned eight entrances.
If V.7.6 is known as the House of Paris because of the graffiti on its façade, and we can see another doorway on the east side of it, that doorway should be V.7.7.
If V.7.6 and V.7.7 are accounted for, there must be two doorways V.7.2 and V.7.3, perhaps also even V.7.4, behind the modern brick wall.
See Van der Poel, H. B., 1986. Corpus Topographicum Pompeianum, Part IIIA. Austin: University of Texas. (p.82).
The doorways will remain a mystery until the rest of the insula is brought to light again.
