When you are planning to build an earth sheltered home, you tend to keep your eyes open for similar structures. Tomorrow I will try to give an actual status update, but for now I will just take a couple minutes to show you the most recent example of earth sheltered architecture that I stumbled upon (it was actually built in 1965).
Perhaps you have heard of Phillip Johnson, the architect famous for his “Glass House”. If you want more info you can do a quick internet search or pick up this book. You may even want to tour his estate next time you are in Connecticut for a couple hours.
What I didn’t know until recently was that he also designed and build an underground painting gallery. To call it “earth sheltered” seems like a bit of an understatement. It was inspired by a visit to the Treasury of Atreus, an ancient (~1250BC) underground tomb that was a marvel of bronze age Greek engineering and stood as the largest dome in the world for over 1000 years. Like a tomb, it was the opposite of the glass house, which made it much better for displaying paintings.
