The huts of Bletchley Park have a very different atmosphere to the larger blocks. Like most of the disused buildings on the site Hut 3 has had various post-war uses. The interior feels more domestic, due to its scale and the carpets and curtains in some rooms. The L-shaped building has a long central corridor with rooms off to either side. 

Information from Bletchley Park Trust website about Hut 3:


The codebreaking huts worked in pairs. The decoded messages from Hut 6 were passed to Hut 3 for translation, analysis and dispatch. Between Huts 3 and 6 was a connecting chute, added to speed up the passing of information from one hut to the other.

Hut 3 is perhaps the only hut constructed to be totally independent, should the need have arisen. It has its own boilerhouse and central heating system, the only hut to be afforded this comfort. For the most part, the huts were cramped and spartan, cold and draughty.

As the importance of the huts grew, so did their staffing needs, so that by the end of the war Hut 3, for example, was no longer a single wooden 1939 structure, but a whole range of locations and buildings on the Park. The same is true of the other huts.
