KA House is a vacation house for a couple who enjoy outdoor activities and spending their relaxing time in a grand courtyard where they can run and play with family members or lay down for a great view toward the lake. The main concept of this house begins with our curiosity: Does a home has to be limited only in indoor space? By this context, the grand inner courtyard is possibly the real home for the owners. Therefore, the main activities area is at the courtyard. In order to ensure that everyone in the house won't miss the activities going on, the court and the lake could be viewed from every space. Everyone can see each other from everywhere in the house. All functions are carefully designed to face the back of the site where the lake is located. The house was designed to enclose the grand inner courtyard. Therefore, the building lays closing to the entrance connecting with the fence. In that sense, the courtyard facing the lake view performs as an actual ‘entrance’, while the front access looks as if it is the rear of the house. Another factor which is highly considered in the design process is the steepness of the site, living functions are close to the court as mentioned but the parking space is placed half-level underground to keep the smooth car arrival and still be private because of different eye level from the outside. The building is separated into two levels. The lower level is for living and dining space which is connected to a spacious deck along with the building. The mezzanine level is utilized for bedrooms. Since it is the house for retreating from city life, many transition spaces are created for the owners to slowly change their mood before they can reach the court. First, the fence is in angled from the road, which leads the car into the main gate as a welcome approach. Then, after parking, the owners can see the courtyard through an opening void but still can't be reached. The way getting into the house starts from bringing the owner along a narrow channel and gradually getting more wider and wider as giving a hint for upcoming spaces. The first thing the path leads to is the tree which is framed by steel beam. Behind the tree is the end of the fence, this composition forces the owners to automatically turn left, then, they will view the huge courtyard connecting with terrace, pool and at the other side, the lake. The other distinctive feature of this house is triangular wooden laths wrapping the upper part of the house. These laths create a diverse degrees of openness through different angles and shapes of light and shadow in different times of the day. In the morning, the soft light flow to the bedrooms creating a playful shadow around the area, while in the afternoon, the light reach the living area and hallways in another pattern. Not only serving in aesthetic aspect but they also act as a sunshade and a visual screen for the air conditioner's compressor.
