Front door - Which provider is recommended?

...
What is BFD?

Double-wing overlapping on both sides. Probably mainly an optical thing :)

Oh, and can someone tell me if 113x235 is still a standard door opening size?

Our front door is about 2.10m high and since the entrance is on the side, practically under the gutter. 2.35m would not have looked good there or the entrance over the gable side and then also raise all the windows to this height.

Are there decent front doors for 2000 EUR?

Two thousand euros and height 235? - linked with "and" in my opinion, no.

Our door(s) installer told me last week that up to 230 cm is still standard, above that it costs extra. However, I don't know if that varies depending on the manufacturer.

Alright, door opening dimension 2.35 is then possibly still 2.30 door height... I have to check.
