Building No 16 (Officers' Mess And Quarters)

This building served as the officers' mess with living quarters for unmarried officers. It was constructed in 1926 to drawing number 1808-13/26 by the Air Ministry's Directorate of Works and Buildings, with some additions to the rear dating from 1935. The building is constructed of dark red brickwork laid in stretcher bond with hipped slate roofs.

Layout

The building forms a complex symmetrical group when viewed from the front (southwest elevation). The central block is a single-storey hipped structure containing an ante-room, card room, and writing rooms connected to the main mess hall with billiard rooms behind. Kitchen and ancillary spaces occupy the areas between these rooms. Set back on each side are lower connecting corridors leading to two-storey wings, which contain single rooms arranged along central corridors. The overall plan creates a wide extended H-shape.

Exterior

Windows are generally timber sashes set within brick soldier arches with stooled concrete sills, though some later steel casements have been added. The main entrance is positioned off-centre to the left, featuring a small concrete canopy below an over-light and large sash windows, including two octagonal flat-roofed bays. A small ridge stack stands to the left of the door. Each connecting corridor has paired doors beneath a moulded pediment over a plain frieze, supported on rusticated brick pilasters. The wings have three-bay outer ends and multi-bay returns, with three large chimney stacks on the outer roof slopes. A wide dormer has been added to the right-hand wing, which continues at a slightly lower level. At the rear, two lofty hall-like units are visible, and the kitchen has a gabled clerestory light with a ridge ventilator.

Interior

The interior features generally simple but consistent detailing throughout, with high skirtings, picture rails, and coved cornices in most rooms. Original timber dog-leg staircases survive in good condition, and substantial wood block floors remain on the ground floor, apparently still sound. The main mess room has a coved ceiling.

Historical Significance

This building retains the architectural style of the first phase of permanent buildings at RAF Bicester, representing the first permanent designs for Britain's independent air force on this uniquely well-preserved and historically important site. Its unique design pre-dates the more standardised approach later adopted by the RAF. The building's planning typifies the principle of dispersal against air attack that Sir Hugh Trenchard, the RAF's first Commander-in-Chief, and his planners integrated into air base design. The central mess rooms are deliberately separated from the accommodation blocks on either side to achieve this dispersal. After 1939, when a new Officers' Mess (Cherwood House, Buckingham Road) was built, this building became the Sergeants' Mess and quarters. It stands at the extreme north end of the domestic site but maintains a visual link with the later Institute.

RAF Bicester is the best-preserved of the bomber bases constructed as the principal arm of Sir Hugh Trenchard's expansion of the RAF from 1923, which was based on the philosophy of offensive deterrence. It retains, better than any other military airbase in Britain, the layout and fabric relating to both pre-1930s military aviation and the development of Britain's strategic bomber force, and the manner in which its expansion reflected domestic political pressures as well as events on the world stage in the period up to 1939. This policy of offensive deterrence essentially dominated British air power and the RAF's existence as an independent arm of the military in the inter-war period, and continued to determine its shape and direction during the Second World War and afterwards during the Cold War. The grass flying field still survives with its 1939 boundaries largely intact, bounded by a group of bomb stores built in 1938-39 and airfield defences built in the early stages of the Second World War.

Military flying at Bicester commenced in 1918, when the new aerodrome was established as a three-squadron Training Depot Station. The site was demolished after the base closed in 1920, but it was selected as a bomber station by the Aerodrome Board as part of Trenchard's Home Defence Expansion Scheme, sanctioned by Baldwin's government in June 1923. General Sir Hugh Trenchard founded the independent status of the RAF upon the concept of offensive deterrence, a principle he shared with Italy's Marshall Douhet and America's General Mitchell. This doctrine envisaged fleets of self-defending bomber formations as the instrument of war most likely to ensure swift victory in any future conflict, and underpinned the justification for the Strategic Bomber Offensive in the Second World War. The RAF's infrastructure was subject to severe political fluctuations in the inter-war period, resulting from both events on the world stage and political and financial pressures at home. Only two of the proposed six A-type hangars at Bicester for the three-squadron station, for which plans were drawn up in August 1926, were built, due to an early deceleration in Trenchard's programme. The next major phase of building formed part of the post-1934 Expansion Period, prompted by the collapse of the Geneva disarmament talks in 1933.

The station opened in January 1928, with the arrival of Hawker Horsleys from Spittlegate on the 10th of that month. The fabric and layout, planned on dispersed principles, retain an identifiable 1920s character and provide examples of the first permanent buildings erected for RAF operational stations. Air Commodore (later Air Chief Marshall Sir) Edgar Ludlow-Hewitt, President of the Aerodrome Board until late 1925 and Commander-in-Chief Bomber Command early in the Second World War, was responsible for the selection and outline planning of these stations, often in close collaboration with Trenchard. Designs for the built fabric were developed in detail by the staff of the Director of Works and Buildings (Major-General Sir Andrew M Stuart, and Major-General Sir William A Liddell from April 1924 to July 1929). The most prominent technical buildings, most notably the guardroom (Building 89) and station headquarters (Building 47), and the buildings on the domestic site were designed in a simple, astylar, neo-Georgian style. The domestic buildings were laid out in an open plan manner, more formally than the technical site to the east, enabling the principal buildings around the parade ground area to play a particularly important role in defining the character of the site. The planning of the technical site is dominated by a strong east-west axis, from the west entrance to the flying field. This road is tree-lined and flanked by the 1920s motor transport group (Buildings 129, 130 and 131), armoury (123) and workshops (90 and 99). It provides clear views towards the hangars to the east and, across the A421, the domestic site to the west.

From the west entrance, flanked by the impressive group of Station Headquarters and Guardhouse (Buildings 146-7 and 89), two service roads branch out: one to the north-east serving the power house and water supply group (Buildings 81, 82 and 84), and one to the south-east serving the Air Ministry Works Department Group (Building 144) and the now-demolished coal yard. The latter, and the main workshops (Building 99), were served by an Air Ministry railway which entered the site from the east.

The 1930s extensions and new buildings carefully match the style of the 1920s scheme. Whilst the married quarters to the north of Skimmingdish Lane and west of Buckingham Road drew their inspiration from the Garden City Movement, the neo-Georgian officers' mess (Cherwood House, Buckingham Road) and married quarters off Skimmingdish Lane reflect the distinct change in the aesthetic quality and design of RAF stations, which resulted from the Air Ministry's consultation with the Royal Fine Arts Commission and appointment of an architectural advisor to the Directorate of Works and Buildings in 1934. The buildings constructed in 1939 for Scheme M, notably the decontamination centres, boiler and power houses, and flat-roofed barracks buildings, are characterised by developed Art Deco characteristics. Buildings 23, 25 and 20 are distinguished by flat protected concrete roofs (to counter the effects of incendiary bombs and minimise the effects of bomb blast) and the use of glazing detail and string courses to give a much more streamlined horizontal design. The increase in aircraft at Bicester was marked by the completion of new C-type hangars in 1937, and the building of a new control tower in 1938 reflected the increased importance given to the need to control movement with the defined zoning of serviceable landing and take-off areas.

1938 saw the arrival of Blenheim bombers, which replaced the obsolete Overstrands with which many airfields had been equipped into the mid-1930s, and in October 1939 the first Halifax prototype made its maiden flight from Bicester. From 1938 to October 1944 Bicester served as an Operational Training Unit, mainly for the training of pilots, observers and gunners for the Blenheim crews of 2 Group. The outset of the conflict saw the completion of the bomb stores group to the south and construction of pillboxes and trenches for the close defence of the airfield, now surviving on the east side of the hangars and in a group to the south of the flying field. The flying field was considerably enlarged to the north and south, with tracks and panhandle standings for the dispersed parking of aircraft characteristic of Second World War bomber stations. RAF Bicester functioned as an Operational Training Unit until October 1944, training Canadians, Australians and New Zealanders as well as British air crews for service in Bomber Command. These Operational Training Units, of which Bicester now forms the premier surviving example, fulfilled the critical requirement of enabling bomber crews (once individual members had trained in flying, bombing, gunnery and navigation) to form and train as units. Crews for the medium bomber units in the Middle East and then the Far East were formed and trained at Bicester and Upwood, with Mosquitos replacing the Blenheims from January 1944. From autumn 1943 it was already serving as a Forward Equipment Unit for the logistical support of Operation Overlord. After 1945, 71 Maintenance Unit formed here as one of the principal aircraft salvage units, responsible for southern England. Crashed aircraft were brought here and reconstructed in one of the hangars for crash investigation purposes. This use, together with its role as a gliding school and the administrative use of the domestic site (DCTA Caversfield), has ensured the preservation of the inter-war character of the site and the rare and consistent preservation of exterior detail and fitments. Post-war redevelopment and encroachment by quarrying has removed most of the Second World War extensions to the flying field.
