This morning we learned the following from a carpenter in our region in southern Bavaria: The regional timber construction companies and carpentries are increasingly having problems with production planning and cost calculation due to the massive increase in wood prices and delayed wood supply. Apparently, a large part of the wood is going at high prices to the USA. The carpenter is in contact with some regional timber construction companies and has recently learned from some that the hardly calculable additional costs are partly and now newly being passed on to the customer in the form of such clauses (must be passed on), otherwise it becomes existentially threatening. He did not know these clauses from previous years. From our internal calculation, we have calculated a wood share of about 35% of the total costs. Thus, with a 5% increase in the price of wood, we come to a starting five-digit amount of additional costs. Of course, we do not find the possible cost increase nice or acceptable, but what alternatives are there now if it is similar with other regional companies in the end. We did not want a big name in the timber construction industry (still with fixed price guarantee here?), it was there sometimes like with a vacuum cleaner salesman ("just sign here and everything will be fine"), opaque and not cheaper, we feel a thousand times better looked after with the regional provider. However, we do ask ourselves whether the current development does not even endanger the solvency of the small wood suppliers through large projects with fixed prices from previous years (in the performance contract, 8% down payment upon contract signing is not nice, but weather-tight shell at 52% payment progress). Somehow we have caught an unfavorable time: wood prices are rising massively, wood for local companies is becoming scarcer, house costs are not reliably calculable, interest rates on construction loans are rising, and the apartment is becoming far too cramped with the children.
