Kennedy O’Callaghan's Bletchley Park visitor centre open doors

  • 1 Comment

Kennedy O’Callaghan Architects has completed the £8 million renovation of Bletchley Park, the home of the World War II code breakers, near Milton Keynes

The campus has re-opened following the restoration of two timber code breaking huts to their wartime condition and the conversion of a third hut into a visitor centre.

Each of the derelict huts have been refurbished and returned to their original layout with all internal post-war partitions removed to restore the open plan arrangement.

Housed in the Block C, where analysis of encrypted messages took place, the visitor centre contains an introductory exhibition to the site as well as a shop and cafe.

Conservation specialists Kennedy O’Callaghan architects was appointed as masterplan and conservation architects following a two-stage competition in 2010.


Architect’s view

Janie Price, director, Kennedy O’Callaghan Architects

Our conservation approach was to let the buildings speak for themselves and to reveal their story. We limited modern interventions to only what was required for stability and visitor safety and we retained authenticity by keeping as much wartime fabric as possible, to allow the buildings to reveal themselves bay by bay.

Wartime colours were reinstated after laboratory analysis and light fittings were reproduced from historic images. The timber huts have been lovingly repaired by the craftsmen on site who took minimal intervention to heart and completed the careful repairs required to maintain authenticity.

    Is the traffic cone a permanent feature to stop people tripping offf the edge of the steps? What about an unobtrusive hand-rail? What about level or sloping access to make access easier for people with walking difficulties?
