subterrainian green house??

I was looking for a good way to grow tomatoes and carrots year round, and someone posted about losing a greenhouse to wind and heavy snow, when I came across this idea

looks like it would work, might need to re-enforce the walls a bit for safety sake

A very interesting concept. That was bigger than our entire yard.

I can see where that might work. It would still have to be fenced. I can see a moose or a bear falling thur that --I would not want to have to deal with fish and game again. Really for 5 years we stared at a basement foundation --NO concrete floor, NO upper decking or roof. Just 4 styrofoam concrete walls. --with a moat around it as no grading was done. It was cute to seee the duck swim around our home to be. We did joke about growing in there as that was the largest cleared spot in the woods.

We have so many feed bags that I am planning on building a dike like wall and covering with top soil and planting ground cover on it. I do have a deep 30 foot 12 foot deep hole that might one day be a pond it might be worth trying something like it there.

It would be sheltered from the winds, I use the pit (pond to be) as a place to store snow from the driveway and it does melt quick. But I do have alot of prodjects on the list for summer as it is. So mayby not this year.
