London Metropolitan University graduate Charlotte Wilson was awarded Best in Show at London graduate show 
FreeRange this year for her proposal to convert a bunker into a museum.
The existing RAF Bempton bunker in Yorkshire, UK is built into a 
cliff-side and would be be transformed into a museum celebrating the 
role of women during war.
The bunker would be dug out in areas to reveal its three  metre-thick walls and create a series of courtyards open to the air.
A  glazed roof over one section would have water flowing over it and 
 down a wall etched with the names of pivotal women from past   wars.
Part of the bunker would protrude out of the cliff to create a viewing platform over the sea.
Here’s some more from Wilson:
“Situated within a unique cliff side location in Bempton lies the  
RAF Bempton bunker. Disintegrating and of great historical interest, it 
 is proposed the site will be sensitively renovated and reclaimed.
‘Women . War . Peace’ will be a new and exciting war museum with the 
   pure focus of Women and War. Journeying through the exhibition will  
  illustrate the compassion, realism, horrors and bravery seen and felt 
   through the eyes of women during war time, both on the front-line and
    behind the scenes. This museum interrogates the creativity of 
learning    through emotional and experiential spaces and details.
By  breaking out of the bunker from it’s central pit space, the     
architectural language conveys the juxtaposition between the protective 
    shell of the bunker and it’s contrasting dangerous subject matter.  
   Through this process the bunker’s thick 3.3 metre walls are revealed 
 and    with this, external underground courtyards are created, allowing
  for    pause and contemplation throughout the experience. The whole   
experience   will be of constant enlightenment, with natural light   
increasingly   puncturing underground and views being progressively   
exposed.
The bunker accommodates four main stages, Past, Present, Reflection and Remembrance;
Past. The main Exhibition Space is located within and around the  
bunker with the focused narrative being of the two different stories of 
 ‘Women at War’ (situated within the bunkers walls) and ‘Women at Home’ 
 (breaking out of the bunker to create new spaces). This gives the idea 
 of the Women at Home being ‘Behind the Scenes’ and supporting the Women
  at War.
This experience will house the stories of Women from  1914 to 2000   
 through interactive stations, silo spaces and archived  resources with 
   the experience being of an intimate nature. At the  heart of the    
exhibition is an interactive time line structure which  contains an    
immersive eerie environment within it’s walls reminding  the visitor of 
   ‘absence’. This structure is impertive as a collective  point and a  
place   to delve deeper into the information.
Present.  This   experience takes place within the Souterrain and   
courtyard  spaces and is   dedicated to the stories of women of war from
   2000 to  the present day.   Water flows along a glazed roof and 
enters   into the  space flowing down  a  wall, etched with the names of
   admirable Women,  before the tunnel   punctures through the cliff 
face   to reveal a viewing  platform over the   sea.
Reflection  and Remembrance. This  viewing platform   allows for the 
  visitor to  reflect over the  information gleaned whilst   looking out
   to sea. As  this space is  partially exposed, visitors will   begin 
to   feel a sense  of freedom as  they listen to the birds song.
Future.     After  ascending back up to ground level, the visitor is 
  able to  look    back on  underground  spaces with a new perspective 
as   they  wonder  freely   back  along the site. A proposed viewing  
platform  will  rise  into the   sky,  allowing a view over the  
explosive  narrative of  the  site.”
