"The Englishman telephone box is his castle" (c)

"The Englishman telephone box is his castle. Like the London taxi, it can be entered by a gentleman in a top hat. It protects the user's privacy, keeps him warm and is large enough for a small cocktail party".
Mary Blume
The red telephone box was designed by Sir Giles Gilbert Scott (1880- 1960) and, along with the red post box and the red London bus, is an instantly recognizable symbols of Britain.
Scott's design of the K2 cast iron telephone kiosk won a Post Office sponsored competition in 1924. His updated K6 design follwed in 1935.
A leading architect, Scott is famous not only for his telephone boxes. His achievements include producing the winning design for Liverpool Cathedral and overseeing the rebuilding work required at the Houses of Parliament after the Second World War.
The red K2 telephone box was introduced to the streets of London in 1926. It was used solely in the capital and only a few were erected elsewhere under special circumstances.
The K2 is both impressive and imposing, weighing over an imperial tonne. On top of the kiosk, on all four sides is the Royal crest of King George V formed from a series of holes to provide ventilation.
K2 telephone kiosks are older and larger than the more widely used K6 telephone box and are very rare.
 Only about 1500 K2 kiosks were produced and only a few remain today.
