Villa Karma is the headquarters of KARMA. The facade of this house retains its original state since 1936, and there are no obvious cracks and damages. The original French-style appearance is retained and the facade is renovated as invisibly as possible. Considering airtightness and durability, a part of wooden doors, round wooden windows are retained, and the rest of doors and windows are employed with glass, thus highlighting the contrast between the old and new windows. The main principles of renovation are to keep the intact parts and form a new base. For the interior, worn red brick walls and remaining wall covering are revealed due to the wrong construction. Abstract frosted anodized aluminum plate, smooth gold terrazzo and white painted wall and ceiling are adopted to decorate the original base, offering possibilities of learning about its history. The design attempts to interpret the concept of Karma in the space. Both in the interior and exterior spaces, staircase, light and water are arranged in a circular way. Red brick and white wall embrace natural light, and colored lighting lights up the night, realizing an alternation of day and night. Since the client required that people would not feel too dull when they work overtime, colored lighting is used to meet the needs of various activities.
