The concept in my proposal is to use the materials that are usually associated with a mountain house, such as stone, wood and leather, while keeping the modern style of the space. Therefore, the furniture pieces are modern, the TV wall and the built-in shelves behind the dining table are custom, to use the space the best and make it feel high-end. The seating furniture (sofa, armchair, dining chairs) are chosen to be soft, cozy and comfortable.
The dining area is imagined with two separate tables, each one could be extended to seat more people - when both tables are extended, one of them would be moved closer to the living room, and the other closer to the shelves behind. When they're not extended, they would be aligned with each other and with the kitchen island. Currently in the renderings there are 10 chairs, but two to three more could easily be added without moving the tables.
Let me know if you have any questions about the design. If needed, I can tweak some things or make some changes after you review the renderings.
