Synagogue

Peter's house was supposedly a 12 room house with 3 courts. (See V. C. Corbo, "Capernaum" in ABD, vol 1, 866-69. ABD= Anchor Bible Dictionary)

I have the quote if no one has the ABD:

C. The House of Simon Peter

The house of Simon Peter at Capernaum is mentioned many times in the Gospels, so much so that in referring to his house, the Evangelists do so with or without the article (Matt 17:25; Mark 2:1; 3:20; 9:33); alternatively they refer to it with the name of Peter (Matt 8:14) or of Simon and Andrew (Mark 1:29).

The house of Simon Peter was found in 1968 in the first campaign of the excavations. It is situated in the SE corner of a vast insula which extends from the shore of the lake to the Hellenistic decumanus. Its N side lies under the balcony of the synagogue; its E side faces an open area which adjoins the cardo maximus and to which reference is made in Mark 1:33 and 2:2. The archaeological finds show that this house had already been built in the Hellenistic period, and that therefore, Simon Peter must have acquired it when he settled with his clan at Capernaum. The entry to the vast dwelling was from the open space to the E. See Fig. CAP.01. The plan of the house had three courts, around which were arranged the numerous living rooms. Among these rooms were two situated on the S side of the N court, which was the court into which one entered from the street. These two rooms were transformed in the apostolic period into a “house church”; here the excavators found part of the paving of the floor, which was surfaced with lime plaster—the same type of paving, in fact, which was found some years later in the triclinia of the palace of Herod at Macheron. The walls of the house–church were likewise covered with plaster and had painted decorations consisting of Judeo–Christian emblems. Christian pilgrims of the first centuries scratched on these plastered walls sacred and devotional graffiti in Greek, Latin, Syriac, and Aramaic (cf. Testa 1972).

The house of Simon Peter underwent a radical restructuring in the 4th century c.e. when, at the initiative of Count Joseph of Tiberias, a friend of Constantine the Great, the house–church was restructured on the interior with the addition of an arch supporting a new roof. The floor was also resurfaced; a new sacristy was added on the N side, while on the E flank a portico was built. The original entrance of the house, which had opened onto the cardo maximus, was closed, while there were opened two new entrances in the sacred wall—one on the S toward the shore of the lake and one on the N on the new decumanus which had been cut through the insula. This 4th century arrangement was seen by the pilgrim Egeria.
