Matthew 26:58

But Peter followed him afar off, unto the court of the high priest, and entered in, and sat with the officers, to see the end.

The court and the house of the high priest were the same. Peter's following the Lord "afar off" in this instances has been cited as one of the reasons that he faltered and denied Jesus. Had he been with Jesus as was that "other disciple," presumably John, he might have endured without denying his Lord (John 18:13). Other preconditions that led to Peter's fall are seen in that he: (1) contradicted Jesus' word, (2) relied on his own strength, (3) turned to carnal weapons, (4) sustained the Lord's rebuke, (5) followed afar off, (6) accepted a place in the company of Christ's enemies, and (7) warmed himself at their fire.
