Just very briefly about our experience with large companies, medium-sized furniture stores, and a small kitchen studio:
About 5 years ago, we needed a new kitchen for a temporary apartment, including all appliances (sink, dishwasher, stove, fridge-freezer combo, hood). Very small, very simple, the requirement was an absolute minimal budget. We already knew at the time that we would build or buy and probably wouldn’t take anything with us anyway. We went through the usual odyssey and tried everything from IKEA to the premium furniture store. The range went from a display kitchen "just like assembled in the store" for a bit over a thousand in pure white to the premium model for "normally 15,000, but since it’s you and today the moon phase is right" only 9,999€.
End of story: A small, local kitchen studio calculated a price of 2,500€ including installation. Appliances from the budget range of Oranier, refrigerator from Electrolux, visually acceptable, bought! In this shop, the senior is a trained carpenter, his three sons have since taken over, and of them, one is a carpenter, one an electrician, and one a businessman. Fits...
For our house, we didn’t go anywhere else. We had simply calculated (without naming our 15k budget): lacquered fronts on 8m and peninsula, mid-range appliances from AEG, all drawers, 90cm cooktop, ceramic sink, exhaust hood. Price without negotiation in the budget (12k) and they also installed our old refrigerator. We had 2-3 small defects, all of which were fixed, and yes, it is not an absolute premium kitchen. But practical, functional, and also visually a solid thing. Therefore, absolute recommendation for such small family businesses.
