and Ru's last  pix.... after 180 tonnes of soil and clay excavated....

 Nearly all pots have galanthus in them!   It will be much easier to keep the pots from freezing in this  deep  pit-house than it would in an above ground greenhouse.

Impressive, isn't it? !!! 8) 8) 8)

Added  later in December - Ru's  example of temperature comparison, inside and outside the pit .....
"The temperature on the street (Shadow, 1,8 m above the ground) and the temperature in the conservatory at the level of the ground, the north wall."

I predict more digging in the Spring, Ru, for another pit.

No!!!
I have a nervous tic due to this pit!!
Most likely, I restore two old winter pits (2,5x5 meters each).

I'm incredibly impressed as I had never even heard of a deep-pit house before.  Is the reflective material on the walls to increase the light level?  You presumably don't want insulation there because you are relying on the surrounding earth for temperature control?   
Almost in Scotland.

The reflective material for illumination. Very effective!
The upper foils makes a "thermos". Bottom  is strengthened differently. Chance of thermal exchange and air movement under the membrane.

This design is somewhat redundant. I realize that. It was possible to make a greenhouse on. You can put the thermostat (0, + 1 degree Celsius) and convectors. It is much cheaper. But there is a possibility that the electricity is not one day or week. I live in an interesting country :). If this happens, it is sure to be on the street -15, -20 degrees Celsius. Murphy and Parkenson's laws no one didn't cancel :).  What happens in this case ?.

More on the subject of Ru's  alpine pit....

 Nearly all pots have galanthus in them!   It will be much easier to keep the pots from freezing in this  deep  pit-house than it would in an above ground greenhouse.

"The temperature on the street (Shadow, 1,8 m above the ground) and the temperature in the conservatory at the level of the ground, the north wall."

 Certainly shows a benefit from the pit. :)

More from Ru in the temperatures in and out of  "the pit" :
" Night 1.01.2016-2.01.2016. on the street  -14,-16. in the pit + 3, + 2. are two of the convector 0,5 and 1 Kilowatt. So, bottom line, 1,5 kilowatt -16 on the street holding stable plus at the square 72 meters Square (Volume 205 M)."

No problem with water? Here, it would have been pools at this time of the year!

But I know they will work with good drainage in the floor.
A friend of mine built one several years ago and he made "holes in the wall" (he used drainage pipes through  the foundation) where he planted all kinds of heat loving trees and shrubs. No soil inside the house and the roots were very deep and below the freezing zone.
