So interesting

Couple of years😂😂. Typical painted siding in norway last 40-50 years. With painting every 5 to 10 years. The siding in the movie are probably some sort of stained+treated. So its CU treated(its green if you cut it) then it's treated with linseed oil with different colours, boiled under pressure. Some are also treated with ironsulfate. 60 years lifespan should be no problem with regular restaing.. edit; underestimated a bit.. added some years due to the fact that some manufacturers gives a 50 year guarantee against rot on their modern cu+stain siding🫡

The problem with them bringing out the metal to the edge (or just proud of) the siding is that it bent around the jambs to form the flashing. I personally would have just done a bunch of traditional flashing (fluid or SA) to cover up all of the rough opening and then used the aluminum as more of an exterior cladding/finish. I know it's a rain screen. But I don't even like the way they did the rain screen with it being tripple thick and not using PT lumber. But they sure do like to build in a very expensive way. My clients want something that will look great and come in on budget. Doesn't take much for a home build to cost a million dollars. Furthermore, that siding is nicely designed with the slops cut into it. But all that siding is going to be crazy money to maintain and re-stain on a regular basis, or it's going to look like crap in a couple years and then eventually rot. I know when the government builds a school in america, this would be value engineered out.

The widow pans look good. They could be enhanced on a custom home by adding a 90 copper cap vertically that turn over the joint between the wood and the painted sheet metal. They could be stuck on with adhesive to avoid holes and to accommodate variable expansion rates of the wood and metal.

At all of those 'simpson' brackets that suspend the wall up about 3/4" (19mm) ... is there some type of shim to support the wall ??
