Major Project: Influence Maps for the Lair

Now that I've decided to move forward with the villain lair belonging to the Cambridge Five I'm deciding on the style the house will be set upon in between the 1950s and 70s. I want to incorporate a mixture of upper class British with a subtle underlining of Soviet design. The secret lair will be a customised house of the privileged Cambridge Five and won't adhere to 'normal' standards of houses from that age.
A big thanks to Phil as well for pointing me towards the Spy Vibe blog that has a good source of spy-esque images.

I will also be looking at art movements from those decades to further enrich the design of the lair.
