The post office and its story an interesting account of the activities of a great government department

Wattles and mud were the building materials of our remote ancestors, and it has been said that we are reverting to the old method, only British mud has given place to British concrete, concrete of Thames ballast and Portland cement. The outer walls are only 7 inches thick, but the frontages to King Edward Street and Newgate Street are faced with Portland stone with granite plinths. To see fully the effect of the reinforced concrete in building one has to examine the back elevations, where there are no stone facings. But even with its false but ornamental front the building has nothing of “the solemn and spacious Greek charm of the delightful old front in St. Martin's le Grand.” The Post Office gains in spaciousness and utility what it loses in architectural beauty. The building consists at present of two parts, a block facing King Edward Street which contains, on the ground floor, the new Public Office, and on the four upper floors the offices of the Controller of the London Postal Service. The other is a much larger block containing the main sorting offices both for foreign and colonial correspondence, and for the E.C. or City district. The actual foundation is only 3 feet in depth, and not one of the floors is more than 3½ inches in thickness. Between the two blocks is a loading and unloading yard for the mails, and on the west side of the second block is a large yard and unoccupied space left for such future additions as may be required for growth of work. The Post Office is learning from experience the value of the margin, and that there is no finality in its advances. It is in this open space below the level of the ground where is to be found the section of the Roman wall which I have described.
