ᐅ Warendorf Series W1 – Does anyone know it?

Good evening,

I currently have a quote for €13,700 all-inclusive.
There is relatively little information online about Warendorf, and almost nothing about the mentioned series.
Does anyone know this brand and can share any thoughts on quality and price?
By the way, these chairs and the downdraft extractor will be removed. Drawers will be installed instead.
