What a dome is like at minus eight

Warm. The stove is lit before you come back from dinner, the floor is heated, and the duvet is rated for minus ten. The panels collect a little frost at the edges by morning, which is the most beautiful thing about the place in January. What you do need is shoes you can pull on in the dark for the walk to the house.
