K6 Telephone Kiosk

The K6 telephone kiosk is a standardised design from the 20th century, constructed of cast iron and painted red overall. It features long horizontal glazing in the door and sides, with applied crowns on the top panels rather than perforated ones. Rectangular white display signs reading "TELEPHONE" are situated beneath the shallow-curved roof. While the internal equipment is modernised, the kiosk retains about two-thirds of its original glass windows, with the remainder replaced by Perspex. A small section is missing from the bottom right-hand corner of the door.

The kiosk is situated at the southern end of Sandwich, on the site of a Scheduled Ancient Monument. It stands on the same side of New Street as the Sandwich Arms Public House and seven listed bollards, approximately 20 metres to the north. To the north east, across the road, are six listed bollards, a railing on the bridge at Mill Wall, and a wall and bridge of the Delf Stream, also around 20 metres distant. These listed buildings create a collective group with the kiosk, affording a close visual relationship when viewed from both sides of New Street.

Designed by Giles Gilbert Scott in 1935 to commemorate King George V's Silver Jubilee, the K6 kiosk evolved from his earlier K2 design of 1924. The K6 represented a more streamlined, compact, and cost-effective approach to mass production. Over 70,000 of these kiosks were produced, and they remain an iconic feature of the British streetscape.

The kiosk is designated at Grade II primarily because of its strong visual connection with the five other listed buildings in the surrounding area.
