1. Consistency in color and texture: By choosing a consistent color or texture for both the interior and exterior surfaces of a building, the facade will complement the interior design.
2. Integrating materials: Materials used on the exterior of a building must be harmonious with the interior furnishings. Matching between the facades and the interior can be by using principles of form, line, and color, thus creating a continuous flow.
3. Building shape: A building's exterior shape can be regarded as one of the essential aspects that complement interior design. The building's shape will have a significant influence on the interior layout, based on the building's design, materials, colors, and landscaping.
4. Furnishings and decor: The type of decor and furniture inside a building can impact the exterior's design. For example, a modern decorated interior requires a modern and sleek design in the exterior.
5. Lighting: Lighting plays a significant role in both interior and exterior design. Lighting fixtures and designs that complement the building's facade will enhance the building's overall design.
6. Entryways: The building's entrance is the first element that visitors notice. The main entrance should provide a preview of what lies beyond the doors. Thus, the exterior design should reflect the interior design through the doors and entrances by integrating the theme, color, and textures.
