Hello Matthias,
we also intended to build with Schl. Bk. The last entries are already a few days old and I am interested in how it has gone so far. Last week I asked 2 other builders about their experiences and the result was, to put it mildly, catastrophic. Quote: "If you still have the chance, keep your hands off it." Unfortunately, there are very few reports of experience and I am very curious about what you have to report.
Best regards Lulac
