We do not have a Swedish house even though it almost looks like it. The wall construction with solid wooden exterior walls is similar to Thoma Haus. No idea if they still exist in the same form as over 20 years ago. Our general contractor was Zellbau in Bad Waldsee, which no longer exists. It was carried out by Holzbau Walser in Bad Schussenried, whom I can warmly recommend - both professionally and personally, and there is a lot of nice things to see on their homepage.
I am very happy about the thread. I really like this style and would have liked to build one or two bay windows, a front veranda, and even a turret at our place :)
