Herod did not build the Temple; he extensively refurbished it. It (the second Temple) had already been standing for centuries by his time. The Temple itself as reconstructed by Herod was of the same dimensions as that of Solomon: 60 cubits long, 20 cubits wide, and 40 cubits high (each cubit is about one-half meter, or one and one-half feet). This space was divided into the Holy of Holies and the heichal. The former measured 20 x 20 cubits, while the latter was 20 x 40. Side-structures, as in Solomon's Temple, afforded space for three stories of chambers on the north, south, and west sides of the Temple. These chambers were connected by doors; and trapdoors afforded access from those of one story to those of the story immediately above or below. The whole breadth of the structure including the side-buildings was 70 cubits. East of Herod's Temple there was, as in Solomon's, a porch, 100 cubits wide, 100 cubits high, and 20 cubits deep, thus extending 15 cubits on either side of the Temple. Its gateway was 20 cubits broad and 70 cubits high. While (as mentioned above) Herod didn't change the dimensions of the Temple itself, he did enlarge the Temple Mount and its outer walls, which were some 900 cubits long on each side.
