Brick chimney or prefabricated fireplace?

thank you for the quick reply.
If the construction company does it, is the interior of the fireplace already included?! or who does that?!
I have seen a few offers where the fireplace is lifted completely finished into the house. Is that better than a self-build system?!

Hello,

If the builders do it, does that mean the interior of the chimney is already included?!

You should at least read

Answer €uro from 23.01.12: " => Prefabricated parts: casing stones and inner pipe (glazed) including accessories! There are plenty of suppliers for this. But, like everything, it must be carefully planned: flue pipe connection, diameter, condensate, effective chimney height, separate combustion air supply...."

Kind regards
