We also have L-bricks for the neighbor to retain the terrain towards the east (that is the side visible in the avatar) (on that side, it will not be a balcony as it currently looks, but a terrace). We will also need additional retaining walls for the terrain (in the front, on the south side of the house, the basement will be sloped down and on the left and right we will need retaining walls), and these will be made of concrete. The house itself and the basement will only be made of wood. Moreover, wood studs, because the insulation values are simply better there. It will probably end up being a KfW40 house, but without storage. We will have a larch slatted facade. We are building onto my mother’s house, which is white, and the new addition should stand out a little but harmonize. We thought it was tacky to just slap another white house onto it. In addition, a natural wood facade is absolutely low-maintenance if you accept the inevitable graying. We even find it very pretty. We are not building near Augsburg but somewhat further south, near Landsberg. I have absolutely no worries about the wooden house. In Scandinavia, they have been building wooden houses for centuries, and they are still standing today. Admittedly, I was a bit skeptical about the wooden basement, but rather whether our groundwater level is low enough. Because that is the only problem: if groundwater gets under such a wooden basement house. And then the problem is not the tightness, but that it can float.
