In Episode 12, Kim explores the different elements that, when used thoughtfully, will help to achieve a balanced design. Style can be formal or informal, traditional or contemporary, country or industrial, but it should weave a thread of continuity throughout the home. Color, another very personal choice, will influence a room's design. So will the high or low contrast of color. Varying the textures in a space will make the design more interesting. Scale can be a tricky concept to understand, but keeping in mind the human scale is most important. Straight and curvilinear lines both play a part in the way a space feels. Finally, Kim discusses the different types of symmetry which can make a room feel formal and traditional, or relaxed and unexpected.
