For "Survivors" Eyes Only

[Sol Invictus]

Clustered energy efficient homes.

Skara Brae on the Orkney Isles. Bear with me and I will explain.

These are ancient, older than the pyramids houses found after a devastating storm hit the islands. They are stone and wood roofed houses covered with a layer of earth, built semi buried and low to the ground to conserve heat.

Now, they actually had interlinking 'tunnels' between each home, so to move from one to the other you never actually had to go 'outside'. This also had a huge benefit as you would share the heat from a fire between many homes. In short, a 'communal central heating' system.

me thinks it would be a good idea to build this way, as a semi buried and earthed over home would be very hard to spot from the air or ground if it was camouflaged the right way.
