Which veneer / clinker is this? Who is familiar with it?

Yes, you will probably have to add a bit more for that. The plain red ones cost around 60 cents, something like in the picture is more in the range of 1.60-2€.

Not necessarily

Our lag was net at €705 / 1,000 pcs.

Also like it. Maybe a bit too reddish. Which stone do you have?

Flemish Antique by Muhr

A house nearby, I believe, has the stone from your example. It is from Wienerberger from the Terca or similar series

Oh thanks I'll find out. Did you order directly through a [GU] or did you order yourself from the building materials dealer?

We chose the stone from an exhibitor. Then our structural builder had to order the stone from the exhibitor through the local building materials supplier. In the end, four parties profited from it -.-

1. Manufacturer
2. Exhibitor
3. Building materials supplier
4. Structural builder
