Reference excerpt

The red telephone box is a telephone kiosk for a public telephone designed by Sir Giles Gilbert Scott, the architect responsible for famous sites like Liverpool Cathedral and Battersea Power Station. The telephone box is a familiar sight on the streets of the United Kingdom, its associated Crown Dependencies, the British Overseas Territories and Malta. Despite a reduction in their numbers in recent years, the traditional British red telephone kiosk can still be seen in many places throughout the UK, and in overseas territories, the Commonwealth and elsewhere around the world. The colour red was chosen to make them easy to spot. From 1926 onwards, the fascias of the kiosks were emblazoned with a prominent crown, representing the British Government. The red phone box is often seen as a British cultural icon throughout the world. In 2006, the K2 telephone box was voted one of Britain's top 10 design icons, which included the Mini, Supermarine Spitfire, London tube map, World Wide Web, Concorde and the AEC Routemaster bus. In 2009, the K2 was selected by the Royal Mail for their "British Design Classics" commemorative postage stamp issue. Many of the phone box designs are protected by trade mark registrations and copyright, held by British Telecommunications plc. In 2019, the prototype K2, located at Burlington House in London since 1924, was listed to Grade II* in "recognition of its iconic design status".

Design history

K1 The first standard public telephone kiosk introduced by the United Kingdom Post Office was produced in concrete in 1921 and was designated K1 (Kiosk No.1). The Post Office had taken over almost all of the country's telephone network in 1912. Some local authorities refused to give permission for the K1; Eastbourne Corporation insisted that the kiosks could only be installed if they had thatched roofs. The design of the K1 was not of the same family as the familiar red telephone boxes. As of 2021, there remain fourteen K1 boxes in the UK, including seven that are in museums and museum collections. A further two remain in the Republic of Ireland. Seven of the UK's fourteen have been listed at Grade II by Historic England, some of them still located on British streets, including one situated in Trinity Market in Kingston-upon-Hull, and another in Bembridge High Street, Isle of Wight.

K2

The red telephone box was the result of a competition in 1924 to design a kiosk that would be acceptable to the London Metropolitan Boroughs which had hitherto resisted the Post Office's effort to erect K1 kiosks on their streets. The Royal Fine Art Commission was instrumental in the choice of the British standard kiosk. Because of widespread dissatisfaction with the GPO's design, the Metropolitan Boroughs Joint Standing Committee organised a competition for a superior one in 1923, but the results were disappointing. The Birmingham Civic Society then produced a design of its own—in reinforced concrete—but it was informed by the Director of Telephones that the design produced by the Office of the Engineer-in-Chief was preferred; as the Architects' Journal commented, "no one with any knowledge of design could feel anything but indignation with the pattern that seems to satisfy the official mind". The Birmingham Civic Society did not give up and, with additional pressure from the Royal Institute of British Architects, the Town Planning Institute and the Royal Academy, the Postmaster General was forced to think again; and the result was that the RFAC organised a limited competition.

The organisers invited entries from three respected architects and, along with the designs from the Post Office and from The Birmingham Civic Society, the Fine Arts Commission judged the competition and selected the design submitted by Sir Giles Gilbert Scott. The invitation had come at the time when Scott had been made a trustee of Sir John Soane's Museum: his design for the competition was in the classical style, but topped with a dome reminiscent of those designed by Soane for his own family mausoleum in St Pancras Old Churchyard, and for the mausoleum for Sir Francis Bourgeois at Dulwich Picture Gallery, both in London. However, Gavin Stamp thinks it "unlikely" that Scott was directly inspired by either of these precedents, arguing instead that "a dome above segmental curves is, in fact, a logical solution to the geometrical problem of designing a sculptural termination to a square pillar when a flat top is not suitable".

The original wooden prototypes of the entries were later put into public service at under-cover sites around London. That of Scott's design is the only one known to survive and is still where it was originally placed, in the left entrance arch to the Royal Academy at Burlington House. In 2019, it was listed to Grade II* in "recognition of its iconic design status". The Post Office chose to make Scott's winning design in cast iron (Scott had suggested mild steel) and to paint it red (Scott had suggested silver, with a "greeny-blue" interior) and, with other minor changes of detail, it was brought into service as the Kiosk No.2 or K2. From 1926 K2 was deployed in and around London and the K1 continued to be erected elsewhere.

K3 The K3, introduced in 1929, again by Giles Gilbert Scott, was similar to the K2 but was constructed from reinforced concrete and intended for nationwide use. Cheaper than the K2, it was still significantly more costly than the K1 and so that remained the choice for low-revenue sites. The standard colour scheme for both the K1 and the K3 was a light stone colour, with red glazing bars. A rare surviving K3 kiosk can be seen beside the Penguin Beach exhibit at ZSL London Zoo, where it has been protected from the weather by the projecting eaves and restored to its original colour scheme. There is another in use at Rhynd in Perthshire.

Worked examples

Example 1 — a first encounter with Red telephone box

Start with the simplest possible case. Write down what Red telephone box claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Red telephone box before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Red telephone box ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Red telephone box

In research
Red telephone box appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Red telephone box in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Red telephone box is common in secondary-school and first-year university syllabi. It links to neighbouring topics BT Group buildings and structures, Culture of the United Kingdom, Listed buildings in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life
Look for Red telephone box outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
