This project is an extension of the first house, W House I, due to the expansion of usage needs. The owner wanted to move to the new house as their primary residence and turn the first house, W House I, into a guest house.

The design challenge arose from the owner's desire for a single-story house where everyone in the family could see each other and engage in activities together throughout the day. At the same time, the owner greatly enjoyed the beautiful mountain view from the rooftop of the original house and wanted to maintain space for their two pet cows, allowing them to walk and graze.

The design solves these needs by elevating the single-story house to a height of 7 meters, matching the height of the original house's rooftop. It’s as if the house has been lifted on stilts, creating a two-story effect, while leaving the ground level as a garden and open space for the cows. The upper floor of the house has a balcony around the house, allowing for a 360-degree view, so you can walk around and enjoy the view at different times. The swimming pool is also elevated to this level.

The house is designed with a two-layer surface: the inner layer is glass, and the outer layer is a slatted deck that can be opened or closed for privacy. The entire structure rests on two large concrete walls, which are long-span walls, and the floor is constructed with a Waffle Slab, solving technical challenges and adding interesting features to the home.

The materials used throughout W House II are raw concrete, flowing from the exterior to the interior as wall surfaces. The mood and tone of the house emphasize warm tones. The wood used is a natural tone, with maple wood selected for its distinctive grain pattern and its ability to complement concrete well. Green India stone was used in the kitchen area to give the house a more contemporary feel. In the central living area, an oversized sofa was designed, allowing for flexible seating arrangements to accommodate various activities, making this space the heart of the house where everyone can gather throughout the day.
