I am currently working on a project building a folly in a field next to my parents' summer house in Sweden. The idea is to build a wooden dome, partially buried in the ground, merging the international concept of a folly with a more Scandinavian type of medieval architecture. The end result will be a more humble dome structure than the images above, connecting it with local church and secular architecture. I am hoping to begin building this summer but as it will be rather costly I am prepared with a ten year plan. I will keep updating with more information as I go along. Help will be much appreciated.
