Sun protection glazing + glare protection or roller shutters/venetian blinds?

Hello everyone,
my family and I are facing the decision whether we should use roller shutters or sun protection glazing + internal blinds for the south side of our single-family house new build.
The problem: To get a roller shutter box above the very tall windows, the entire ground floor would have to be planned about 10cm higher again and the already steep staircase would become even steeper. Additional costs according to the architect of about €15k for roller shutters and extra work for all trades due to increased wall area.

I am unsure whether we will ultimately be happy with sun protection glazing + blinds. You just never get the roller shutters/shutters installed as nicely as they are now. Budget-wise it would be possible, but we would have to forego other things that we might possibly retrofit later.

Anyone have experience with sun protection glazing + blinds? Are you happy with it?

It's rubbish. Ask yourself why many office buildings have sun protection glazing but still have EXTERNAL sun protection. You won't be happy with it.

Hmm. I would say: Make the windows 10cm smaller and it will fit. If the 10cm are that important, you should bear the additional costs.

In new buildings, external blinds. Solar control glazing is too darkening in winter and provides too little heat protection in summer.

Thank you for your input. Unfortunately, that confirms my suspicion. We are reaching budget limits. The windows are currently 240cm high, which is already very nice and meant to be a highlight. About 10cm would be reduced from that. 230cm is still very nice. I think we need to renegotiate. Unfortunately, as a builder, you are no longer in a good negotiating position. The architect mentioned that the blinds are supposed to be prone to faults; does anyone have experience with that? During storms and such, they are of course automatically retracted (KNX).
