K8 Telephone Kiosk

K8 Telephone Kiosk, Grove Hill, Highworth

This telephone kiosk is constructed from six cast iron parts and an aluminium door. Three sides of the kiosk, including the door, contain large sheets of toughened glass set in rectangular frames with rounded corners. The kiosk has a square plan with a flat roof dome glazed with toughened glass on four sides, each pane bearing rectangular frames with rounded corners and the word 'TELEPHONE' on a white background. The entire structure is painted red.

The K8 was designed by Bruce Martin following a design competition held by the General Post Office in 1965. Bruce Martin studied engineering at the University of Hong Kong before qualifying in architecture at the Architectural Association. He worked for the architectural department at Hertfordshire County Council and was part of the group responsible for the 'Hertfordshire Experiment', a progressive primary school building programme using pioneering construction techniques, pre-fabricated buildings and child-centred design.

The General Post Office's design brief required that the kiosk be easy to reassemble on site and straightforward to maintain and repair. Unlike the K6 design, the K8 was given interchangeable components to meet this requirement. The brief also stipulated that the kiosk should last at least 50 years and be recognised as the UK's next generation of red telephone boxes. To achieve this, Bruce Martin undertook a meticulous analysis of Scott's K6 design, simplifying and reducing the high number of components to just 7 principal parts. The design offered a choice of two roof types: a lozenge shape and a cast-line form, of which this example features the latter. The reasons for using both varieties are unknown, but both types were produced.

The K8 first appeared on streets in 1968. By 1983, 11,000 had been manufactured for the UK by the Lion Foundry, though only 12 are known to have survived. This kiosk represents the final design in the series of red telephone boxes and demonstrates an innovative translation of the iconic K2 and K6 designs through modern construction techniques.
