 Then there is the biozola house, that's also a very nice construction, it's sort of a house in a greenhouse and there is an experimental or a show site where you can actually stay in such a house for a few days if you want to experience it and the designs are beautiful. I've been in one so I like the approach so it's maybe here you see it best, there is a greenhouse all around so the sun is heating up but the heat is going all around and heating the whole building up from the inside and it's a pleasant space there so that's something where you can have a good time in most parts of the year.
