On exterior surfaces of buildings, light is not only for safety. Correct residential lighting should enhance the complex and have a design that is integrated into the aesthetic context of the surrounding environment, creating a feeling of continuity and harmony of design.

Light, used harmoniously and with taste, can enhance the exteriors of buildings and gardens and create evocative views. To effectively illuminate houses and gardens, it is necessary to create focal points of visual attraction, measuring the distribution and the amount of light, so as to choreographically highlight especially important areas.
