ᐅ (Varying) installation depth of the window frame

Dear forum members,

The windows were recently installed in our new build.
We have some windows with roller shutter boxes mounted on top, and some with venetian blinds.
What surprised me a bit is the different depth of the window frames in the exterior wall. The frames for the roller shutters are noticeably set further out than the others (about 7cm (3 inches)).
Furthermore, I find the frames for the venetian blinds positioned quite far inside as well… there will also be insulation and plaster applied in front of them (a total of 16cm (6 inches)), and the frame is already recessed about 12cm (5 inches) inside. This means, in the end, it will be almost 30cm (12 inches) deep, and the sash frame will be even a few centimeters deeper from the outside.
Inside, the window frame is almost flush with the interior wall, so the windowsill inside will be very narrow (maybe 8–10cm (3–4 inches)).
Inside, all the shutter boxes are flush with the wall, which fits well. Maybe this is simply a structural issue?

I can’t quite imagine it yet, but somehow it might look odd from the outside if the window ends up being recessed this deeply?
Attached are pictures of both versions.

There are often minimum overlap requirements for the shutter/blind boxes from the exterior insulation (ETICS) side. You can’t just move them around freely, aside from the thermal bridging issue.

I also suspect there is a minimum overlap. If that’s the case, then everything will just stay as it is.

People probably don’t skimp on expanding foam there either...

Well, the gaps have to be filled somehow.

This is the result of poor planning and design. Not to mention the execution defects. I cannot understand how anyone could come up with the idea to install both venetian blinds and roller shutters together, especially when they have different dimensions. It really looks awful.

Are you referring to the different installation depths as execution defects?

After raising this issue with my contact at the homebuilding company two weeks ago, the problem was delayed for two weeks and is only now being addressed again. I would be willing to waive any warranty claims related to thermal bridges, etc., in that area, but unfortunately the facade work has progressed further by now — insulation has been installed and so on. My contact now wants to gather all the facts and provide us with a price quote. So, making any changes could become costly. If they had dealt with it immediately two weeks ago, before the facade was in place, it probably would have been easier to resolve. It feels somewhat like a tactic to me.

If I had known that the venetian blinds would cause such problems, I would never have switched from roller shutters. We only did that based on a friend’s recommendation. In principle, it’s a good idea for the living areas, but I expected better advice during sales and installation.

We are definitely quite disappointed now, especially since we had planned nice window sills in the living room. We are even considering putting a shelf or something similar behind the sofa just to have a place to put things. It’s a shame that you have to worry about these kinds of things in a new build...

The construction company has kindly agreed to position the windows further outward, so that all the window surfaces are flush. Hats off, I had almost given up on that.
