Do we think that grass hut from the finale was custom built?

Or like, did they call up the production design team from 'Midsommar' and asked them to build one again.

I get that they are in Iceland but when Clayton said, "Susie, meet me in the countryside" I doubt she thought she was going to a large grass hut surrounded by fire pits. If it wasn't raining, that would have been a legit fire hazard.
