Next design for the story about stealth infiltration to uncover a secret weapons project. This is the Commanders office and his villa in the mountains. He is a botanist and is researching plants and how to use them for his secret project. He loves plants so he ordered the villa be converted with a terrarium instead of the window. So he can cultivate and look at his flowers much more pleasantly. He enjoys having his fellow officers for expensive cigars and drinks. He is equiped with an Enigma machine to send messages to HQ.
I love doing worldbuilding like this. Hope you like it too. Designing the window frame went through a few iterations and frustrations.
