K8 Telephone Kiosk

A K8 telephone kiosk at Langton Park, Wroughton. This kiosk was built to a design by Bruce Martin following a General Post Office competition held in 1965, and first appeared on the streets in 1968.

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

Bruce Martin (born 1917) 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 initiative employing pioneering construction techniques and pre-fabricated buildings.

The General Post Office's design brief required the K8 to be easy to re-assemble on site and straightforward to maintain and repair. Unlike the earlier K6 design, the K8 was given interchangeable components. The kiosk also had to last at least 50 years and be recognised as the UK's next generation of red telephone boxes. To achieve this, Bruce Martin analysed Sir Giles Gilbert Scott's K6 meticulously, simplifying and reducing its numerous components. The resulting K8 design had only seven principal components and offered a choice of two roof types: a lozenge shape and a cast-line. This kiosk displays the cast-line roof variant, though the reasons for the division between the two types remain unknown.

By 1983, approximately 11,000 K8 kiosks had been manufactured for the UK by the Lion Foundry, of which only 12 have survived, making this a rare example of this once common design and the last in the series of red telephone kiosks.
