The house is located in suburban area at Yangpyeong, Korea, and was designed for a couple. The husband is a college professor at art department. The site is placed on a hillside with a sweeping view and a broad slope to the northwest, and faces a mountain to the south. It poses a particular challenge that the orientation of the house and of the main view cannot be the same.
The couple wanted a place for various social activities and events, in addition to residence, after the husband retires. At the house, they expect to continue to work on art, hold small exhibitions, academic gatherings, art classes for children in the community, and mini concerts. To do so, they wanted a separate guest house apart from the main house, an independent study-cum-atelier for the husband, as well as a multi-purpose space that can accommodate about 20 people.
Considering the site conditions and the couple’s needs, we decided to maximize a view to the northwest and design a flexible space to accommodate various events, with a careful section planning. Using the slope, we put south-facing living quarters on the upper level, separated into a main house and a guest house. On the lower level, we designed a multi-purpose room that connects the two buildings. By bending a corner at the northwest side of the main house, a sweeping view could be secured.
The most notable spatial feature is a stepped courtyard that spans the two levels, located between the main house and the guest house. This serves as a spatial center of the house, and is the most interesting place. The courtyard connects the upper and the lower levels, and can flexibly accommodate various events. The courtyard is topped by a viewing deck that connects the main house with the guest house, serving as a scenic point of the house with a panoramic view.
As for finishing materials, dark gray bricks and zinc panels, light gray cement panels were used to create a monochromatic exterior so that the house can naturally blend into the surrounding. Inside the house, also monochromatic colors and natural tone of white birch were used to emphasize the contrast with the surrounding view seen through windows. Architectural elements of the exterior and interior of the house were linked, thereby expanding spatial scope of the house as the exterior space is perceived as an extension of the interior, and vice versa.
External insulation was applied throughout the building envelope including the roof, and system windows, double-layered windows were installed. As for heating system, geothermal boilers, fireplace, and solar panels were used for enhanced thermal efficiency. To cope with cold weather in winter, the residential area was put to face the south, and the house was punctuated with proper openings. Also, exterior materials of high thermal capacity were used, and the deep-seated courtyard finished with bricks retains heat during the day and emits warmth late into night, reducing heating burden. To mitigate heat in summer, folding doors were installed between the back of the multi-purpose space and the stepped courtyard, which can be opened to create the Venturi effect for efficient air circulation. Also, vapor-cooling through water areas cools the air and reduces cooling burden during summer.
