We have basically finished the planning phase. The building permit application has been submitted. Now we are moving into the details.
We started with the windows and have reached a standstill. I hope you, and especially you @11ant, can help us.
It concerns our floor-to-ceiling aluminum windows in the open-plan living area. Both are designed as lift-and-slide windows. Clear ceiling height is 270cm (106 inches), window height 240cm (94 inches). We don’t want a corner window—the structural engineering would be too complicated. It has been agreed with the structural engineer that a 24x24cm (9.5x9.5 inches) concrete support column plus insulation will be placed in the corner. (The picture still shows a longer masonry wall, but this will be changed.)
Which solution should we choose for the roller shutter boxes?
a) Flush-mounted box matching the masonry made from Poroton. The problem here is the lack of a bearing surface on the side of the concrete support column.
b) Flush-mounted box made of EPS (36.5cm (14 inches), width fitting the brick), installed flush with the window, meaning it does not require a bearing surface.
c) Increase the window frame depth by 30cm (12 inches) and use a 15cm (6 inches) wide metal roller shutter box. This could be ordered either flush-mounted or façade-flush with a visible metal cover.
d) Instead of increasing the window frame, install an approximately 18cm (7 inches) wide lintel consisting of 3.5cm (1.4 inches) EPS plus a 15cm (6 inches) metal roller shutter box.
...
Of course, we would prefer floor-to-ceiling windows in the open-plan room at 270cm (106 inches) height. Aside from the additional costs now... the only solution I could still consider would be surface-mounted (external) roller shutters. What do you think about that? In front of the windows is an undeveloped southwest-facing side with a large field/orchard meadow. How do surface-mounted roller shutters behave in the wind?
Do you perhaps have another solution?
@11ant – what is your opinion as a professional?

@11ant – what is your professional opinion on this? I have never been an expert in corner window blinds, nor do I want to become one; in my opinion, the solution is obvious: don’t make the change that causes the problem in the first place 🙂

Why would anyone want to make a change that creates an installation problem?Because I want to have as little wall bulk as possible in the corner. The planner knew that too. He initially designed the corner with masonry because he wasn’t sure how it would work structurally. It was only after consulting the structural engineer that we got the green light for the narrow concrete support.
