Description from record TR 35 NW 88:
5275 No 34 (Hadley House) St Peter's Street (East Side) TR 3358 1/127 19 5 50 Grade 2. Early C19 facade on a C17 building. 3 storeys, 3 windows. Red brick. Glazing bars missing in windows. Doorway with pilasters pediment, semi-circular fanlight and 6-panel fielded door, top 2 panels glazed. Nos 32 and 34, Bollards and No 36 (Seven Post House) form a group. (1) Hadley House, 34 St Peter's Street, is a fine double fronted, red brick house of the early 18th century, with its original doorway with pilasters, pediment and fanlight. The central door has several steps leading up to it, there being an older cellar under the south east part. The cellar is ancient, and like so many in Sandwich may go back to Norman times. It has walls of stone rubble, which is obviously re-used material, and was probably brought from Richborough. There are some large dressed stones, especially in the north west corner. The two small windows giving on to the street are not original, as they are edged with red brick, but a blocked doorway in the south eastcorner has stone quoins, and must have been the earlier entrance possibly giving on to a stone staircase, connecting the cellar with a chamber. The cellar measures internally 13ft 10ins by 19ft 6ins, thusoccupying about two-thirds of the frontage. Its floor is only 3ft 6ins below street level, the headroom to the 18th century joists abovebeing 5ft 9ins. Most of the cellar floor is of well worn 18th centurybrick, but part of it is cobbled, with the remains of a partition showing that this corner was used for storing coal. The cellar stairs are steep, and of red brick, recently repaired, the treads measuring 8.5ins. They are reached by prising up a trap door beside the main fireplace, proably once inside a cupboard in the rear room. The entrance to the subterranean passages is cut through the east wall of the cellar, close to the stairs, and measures only 2ft wide by 3ft 6ins high. From this entrance the tunnel descends very steeply for about 12ft and then levels out, proceeding in a series of staggered straight sections as indicated on the plan (see illustrationcard). There is a branch tunnel immediately on the left, and this also has staggered sections, while just beyond that is a shaft leadingvertically upwards, but now blocked by a metal sheet. This shaft mustonce have lead up to some outhouse in the present walled garden, and was probably used originally for extracting soil from the workings. The tunnel leads ultimately to the ancient cellar under the Masonic Hall in High Street [TR 33155819] where there is a blocked entrance. This cellar was formerly under the Old Bell and Anchor Inn which was demolished earlier this century. At least two other branches are known, one is said to lead to another blocked entrance in the cellar of the Three Kings in Strand Street [TR 35 NW 87]. The construction of the tunnel is simple, the passages are cleanly cutout of the soil, which is firm sand still showing in places the original tool marks. There is no attempt at lining, or support of anykind; the tunnels remaining at 2ft wide, with the headroom never more than 4 to 5 ft. (2)
