I was looking for:
- Polytunnel functionality rather than "greenhouse beauty"
- A huge tunnel that would fit in a small and already crowded garden (then It will of course not be huge.. more likely quite small)
- As much growing space as possible related to space it will take in the garden
- Good enough winter isolation to really extend the season and add possibly also add heating during early spring
- Hardy enough to stand the snow load and winds during winter
- Practical, with ventilation possibilities etc.
- Reasonable cost
I decided to go for a Palram Bella greenhouse tunnel. It looks like this (image from Palram):

It's 2,44x2,44 meters and it was really the squared measurements that made it possible for me to place it in my garden in a good way (with doors facing the garden instead of just a corner).
I will start the ground work this weekend, and hopefully I will get it delivered and get it together within the next 2 weeks. What do you think?
I will get back with reviews, updates and info on how it will meet my expectations.
