First level
On the ground floor they planned a large public area with a kitchen-living room and a library. But a traditional TV should not have become the center of attraction in such an apartment. Instead, the central space needed to be set aside for a large dining table for long dinners with wine and an island for cooking and gatherings with friends.
On the same floor there is a dressing room for outerwear, the main bedroom and its bathroom, an office, and a guest bathroom.
My favorite technique is creating contrasts. For example, we have a dense green library, and next to it the main living room is light and soft. Or one guest bathroom is made dark, like a fox hole, and the other is light, but they are united by the same material - tiles from the same collection.
