Corner glazing with steel support, which roller shutters / blinds?

Hello,

we had planned a house type (town villa) in our plans.

The floor-to-ceiling corner glazing on the ground floor and also on the upper floor should really stand out, therefore the only solution is a steel support in the corner (as in the picture) - a masonry corner would be 36x36 again and therefore too wide (the windows would no longer look like one part, but like individual windows...).

However, the big problem now is how to install the roller shutters / blinds on this corner glazing. Several companies and also the architect confirmed to us that this is not possible as such.

There would be 4 options:
1) For cassette roller shutters (roller shutter box is integrated into the lintel and load-bearing) there is too little bearing surface, so this option is ruled out.
2) Using surface-mounted roller shutters that are mounted on the outside of the wall. This would work, but these roller shutter boxes look attached and do not really fit the town villa.
3) Venetian blinds or surface-mounted roller shutters: these are placed in front of the window and finished flush with the masonry using a plaster carrier (for surface-mounted roller shutters) or cladding (venetian blinds). However, it is necessary that these windows are set further in. Normally, the windows are set about 12 cm deep into the house; for these windows with roller shutters / venetian blinds, the windows would have to be set about 18 cm deep so that the roller shutter boxes disappear and are no longer visible from the outside...
4) No external shading/darkening - instead venetian blinds etc. inside.

For us, only option 3 or 4 really remain, but on the one hand we wonder whether it still looks good at all if the glass front (south side) (see picture) with all the glass sits 18 cm deep (the windows), while all the other windows in the house sit only 12 cm deep (no roller shutters)?!

For option 5 with the internal venetian blinds/shades we doubt whether this really darkens properly?!

Do you have an idea / what looks best or would be the best solution for this corner glazing?

Best regards Tim

Hello Tim,

There are 4 options:
3) Venetian blinds or external roller shutters: These are installed in front of the window and are finished flush with the masonry using a plaster carrier (for external roller shutters) or cladding (venetian blinds). However, this requires the windows to be recessed further. Normally, the windows are set about 12 cm deep into the house, but with these windows with roller shutters/venetian blinds, the windows would need to be recessed about 18 cm so that the roller shutter boxes disappear and are no longer visible from the outside...
4) No external shading/darkening - instead venetian blinds etc. inside.

For us, only option 3 or 4 really remain, but on the one hand, we wonder if it would even look good if the glass front (south side) (see picture) with all the glass is recessed 18 cm (the windows), while all other windows on the house are only recessed 12 cm (no roller shutters)?!

I have attached a picture of external venetian blinds for you. This is a special external venetian blind fully integrated into the wall surface from the outside. By covering the box with a plaster carrier material, the box can later be plastered over and remains completely invisible. The additional space required beyond the existing frame is only about 8 cm and is therefore very minimal. Also, the inspection opening, which is always accessible from the outside, is advantageous in case there are any malfunctions with the venetian blinds. Since the forum operator removed your picture, I will take as a price indication an external venetian blind of size 60 x 270 cm; this costs with a motor but without electrical connection, completely mounted on the window, about €850.00

Shading on the inside is of course also possible - it is usually cheaper, and it depends crucially on how "dark" you would like it.

What I do not understand, however, is why your supplier did not offer you a corner window where - as with "normal" windows - the roller shutter box sits on the window? In this version, there is a kind of plastic cladding around the corner (2nd attachment) - it looks from the outside like a whole window - in which the roller shutters of both sides run.

Kind regards

Hello,

@BuildingExpert:
Thank you very much for your answer, this is exactly the variant with the Venetian blinds that we are looking for! In my picture in the drawing, I had roughly drawn them like this once, they actually look nice and protect against too much sun. However, with this solution, it is the case (as in my sketch and in your picture) that the windows with these Venetian blinds have to be set further inside. You mentioned 8cm.
When the Venetian blinds are closed, everything looks optimal and nice, I am just unsure how the whole thing appears when the Venetian blinds are open. Then you have the glass side of the house (see Picture 3) with windows that are set 8cm further inside, while the rest of the windows of the house sit correspondingly further outside. That looks inconsistent - or is that not so noticeable!?

The 2nd variant with the corner windows was actually never proposed to us, I suspect either because they would become too expensive or because the corner has to be load-bearing due to the statics!?


Best regards,
Tim

Hello,

That seems inconsistent - or isn’t it that easy to notice!?

No .... it’s similar to wallpapering. You know that you made a mistake at a certain point on the wall and keep looking at it; a visitor would never notice it

The 2nd variant with the corner windows was actually never suggested to us, I suspect either because they would be too expensive or because the corner must be load-bearing due to the statics!?

I don’t have a crystal ball to explain this oversight to you; what is certain is that your provider is definitely not among the inexpensive ones – these two windows wouldn’t have stood out in the overall calculation – and it certainly has nothing to do with the statics

Kind regards

Hello Tim,

... I have searched half the internet, but I just can't find a picture of a city villa or at least a house with corner glazing and these blinds...

I sent you a private message with one reference ... or two, or three. In any case, you can get help there

Best regards

Hello construction expert,

thank you very much for the address. I have written to the provider and will get back to you when I know more

Thank you & best regards,
Tim
