Do you even think the kitchen in this house is too busy? I might have chosen to not do an L, a smaller footprint/ under counter fridge and maybe a different AC solution (If those slats are indeed for AC). Apart from that, I do like the overall simplicity and also can live with the counter.
Would you favor an approach that might be closer to what, say Pawson does with kitchens? I likely would. I can imagine though that kitchens can be a tricky part for an architect and an owner building a house, given the balance of functionality and design. I agree though that I would be the first to sacrifice on practicability for a more coherent design: I am not a cook and only need space for the caterer ;-)
