Naos was used in John 2 20 to describe the whole temple not just the inner part.
20 The Jews then said: “This temple was built in 46 years, and will you raise it up in three days?” 21
Herod’s greatest work, however, was the reconstruction of the temple and its building complex. Beginning in his 18th year (Jewish Antiquities, XV, 380 [xi, 1]), the holy house itself was completed in a year and a half, but the work on the adjoining buildings and courtyards went on long after his death. (Joh 2:20)
