How much does a bay window with a balcony cost?

We had similar experiences, the sellers often patch together from other modules. Transparency = zero.

After post #4 I have already made my thoughts regarding the providers visited

Hello Sabine,

How expensive would a bay window about 4.5 x 2m in size (completely glazed, with venetian blinds) and an above balcony roughly cost?

Solidly around EUR 16-17k (depending on number of windows) plus venetian blinds about another EUR 5-6k, plus railing and flooring for the balcony.

or is there a step out onto the balcony?

Often.

So you should probably plan for about 25,000 euros. It's not exactly a bargain.

Best regards
Sabine
