Hello, two years ago when we extended our cabin, we chose Sundolitt KUB, which we used for our Attefall extension. It was incredibly smooth and easy, we erected the whole extension in a weekend, poured the walls a week later, and on the same day, we put on the roof and the tar paper and had a sealed house. In hindsight, I should have hired someone for the pouring who knew what they were doing; it was not suitable to do it myself with my father-in-law and a concrete pump truck.
Now we've started playing with the idea of another extension, and I think we will use the same system again, but this extension would have larger glass sections (at least 3 m). Is it even possible for a DIYer to handle the reinforcement and more for such a construction?
