Really looks great! That now gives me totally different ideas...
For us, it rather resulted out of necessity because our general contractor was missing craftsmen one after another, including the plasterer; today we are happy about it.
We were able to put a total of 16cm of wood fiber insulation behind it and I wanted to do quite a bit of it myself because it is quite easy to do, or together with a friend. Unfortunately, winter came along and other circumstances arose, so I ended up having it done anyway. I almost fell over at another offer that on the first three pages only emphasized the special features of the wood material and craftsmanship, but which then also had a drastic effect on the price.
We generally like simple, functional things and then had our carport builder do it on an hourly basis, which in the end was totally cheap and we could have helped reduce the hours; I would ask the small local wood dealers if needed. For the wood, we were convinced by ordinary spruce boards in 24mm, which we had cut into 3 widths and then painted ourselves with a Kreidezeit product. Next time I might have the boards planed because unplaned wood is tougher to paint; underneath is the foil intended for the open boarding. Then you can mix the wood as you wish and thus influence the appearance. I just let it happen, the gaps vary somewhat but in the overall view of the house no one can see that, at least I can’t. I wouldn’t have wanted it with the expensive rhombus battens, you can see that at every corner as unnecessarily expensive as well.
We live in the countryside and happily have beautiful flowers in the garden and therefore many kinds of insects. Of course, they always fly into the gaps just as birds like to do sometimes. We find that quite nice because it does no harm to the house.
One advantage I see is that you can unscrew a board at any time, replace it if necessary, screw on all kinds of things and also hide cables or similar underneath afterwards very well. All of that is much more difficult with plaster, also to repair at times, but the main reason is also that we really like it, especially the open wood boarding with the irregular widths.
I got hooked on that on the internet by very chic houses with such boarding. In the end, we built it the same way, only probably at 30% of the cost of what I found on the internet.
I just found 2 more pictures.
