Greenhouse idea for cold area

[Feerie]

Hope you all are well.

Hehehe, some of you are probably still sleeping while I post this.

I would love to build a greenhouse in my garden for my orchids, but the problem is weather. I do have lots of space on the west side of my garden that does receive sun in the morning from the east side, that is not my problem. The problem is winter. We get a lot of frost as well as black frost and snow that we get once a year during the month of June or July, that last about 2 - 3 days. I also do not know how to build my greenhouse that will be right for the orchids in these climates. It get as cold as -10 degree Celsius and in the summer it get as hot as 37-38 degree Celsius.

It there perhaps someone that can assist me with advice. Pretty please.
