Dutch architect Anne Holtrop has proposed two conceptual embassy buildings for the Government Building Agency in the Netherlands. 
The designs (retreat I & II) would both contain a series of rooms distanced from their immediate surroundings for safety. 
Retreat I (above) would have alcoves in a mountainous form and Retreat II (below) would have spaces concealed in undulating terrain. 
Here’s some more from the designer:
Recently I finished an idea project for the Government Buildings Agency (part of ministry VROM). 
It is called Two models for embassies (retreat I & II). 
The work originated out of the need for safety issues concerning embassies. 
What I tried to do is to develop two ideas in models to give a broader insight in this question. One way to defend one self is to retreat, to make a distance. 
That why the work is named Two models for embassies (Retreat I & Retreat II). But a retreat has also a very positive meaning, like a retraite.
