We don't want to have exposed timber walls everywhere. The interior walls will be finally plastered. We can contribute our own labor here, so there is potential for savings. Regards
What speaks against the living area in the basement including access to the large garden for us is that we will build all exterior walls in solid visible wood. We would not have that room climate/feeling in the basement with concrete walls.
That somewhat contradicts the timber frame. By the way, solid wood can also be hidden under drywall and painter's fleece.

Here you can see an example of the wooden wall. There are now a few systems that can implement the solid wood wall very well without glue and plastic. In the construction planning, the electrical system is taken into account and the channels are pre-milled. All good. Wall heating is applied to the interior walls (wooden studs). That also works. ...
So: BSH not glued but with pre-milled electrical channels is among the most expensive things you can get yourself into. (unless you also do a clay plaster with wall heating on top, which would be really great, but not a bargain). Also, extremely demanding in planning! We had (for the entire construction, but especially for the solid wood walls) the opportunity to view the house in 3D during the planning phase and to display, for example, only the electrical layer via layers. That way we could check every electrical channel and every box. Nevertheless, there were still small things that were not perfect. We could then fix those on site since they were hidden by gypsum board. With your intended construction method, that would not be possible (if I understood you correctly). Moreover, there are only a few selected providers who offer this without glue and "plastic" (where else is there plastic in solid wood walls?). These providers are currently either sold out or even overloaded or do not even have material available to build with. That does not fit at all with the planned savings through own work on the interior walls (interior plaster). At the moment I see the construction planning at most as an early beta phase ;)

This way we could check every electrical channel and every socket. Nevertheless, there were still small issues that were not perfect. We were then able to rework them on site since they are concealed by drywall. With your intended construction method, that would not be possible (if I understood you correctly). There are also only a few selected providers who offer this without glue and "plastic" (where else would plastic be in solid wood walls?). These providers are currently either sold out if not even overloaded or have no material to install at all. This does not match the planned savings through own work on the interior walls (interior plaster) at all. At the moment, I see the construction planning at most as an early beta phase ;)
Thank you for your note. We have everything on our radar. The factory planning is of course immensely important. We have a partner for that at hand.
