A kitchen should primarily be practical, but nowadays it is mostly about the appearance; you want to elicit a "wow" from the visitors and get confirmation for great taste.
Kitchens with reach-in profiles are installed even in the smallest rooms, it looks good, but in the morning you run to the basement to get the Nutella because there is a lack of storage space in the kitchen.
But like the concrete fronts, the black fronts will eventually no longer be in line with the spirit of the times. Fashion, especially in DE, changes very quickly.
In the mentioned other forum, someone now also has a styled black kitchen. The problem here is that the moment you touch a front, you see it, always and everywhere. Meanwhile, the owners pull the drawers with dish towels. Of course, they did not expect that, but that is the price you pay for some fronts in matte black. And that for YEARS, it’s not a BO that you exchange if you don’t like it.
As Solveigh wrote earlier, he had only 60cm of work surface on his 270cm long island. The kitchen was certainly nice, but cooking, etc., is torture on 60cm. And no Dekton worktop or black or purple front helps. 60cm is a fact you have to live with for YEARS.
