Matthew Poole and continuators on Ezekiel 40:13

13 He measured then the gate from the roof of one little chamber to the roof of another: the breadth was five and twenty cubits, door against door.

From the extremity of one little chamber on the North-side of the gate, to the extremity of the opposite chamber on the South-side, and so one cubit, and half for the back wall of the one chamber, and as much for the back wall of the other chamber, with the length of the chambers, six cubits each and ten for the breadth of the gate, amounts to 25 cubits.

Either so placed, that the door of the first chamber on the North-side, answered to the door of the first on the South-side, or some think, the doors of the Chambers were two in each chamber in the East, and West parts, and so exactly set, that the doors being all open, you had a clear prospect through all the Chambers to the Temple.
