As an interior designer, there are several fundamental principles I always consider to create visually appealing and functional spaces. These principles include Balance, Rhythm, Harmony, Contrast, Proportion, and Scale. Let’s go through each principle in depth.


Balance in interior design is an essential part of the interior design basics, as it creates a feeling of equilibrium. I constantly strive to equalize the visual weight of objects, colors, patterns, and textures. There are three types of balance I tend to focus on:

Symmetrical Balance
  1. Symmetrical balance: where I place the same items on either side of a central point
Asymmetrical Balance
  1. Asymmetrical balance: where I use different elements but still create a balanced look
Radial Balance
  1. Radial balance: where elements radiate out from a central focal point


Rhythm refers to the way the eye moves through a space. I aim to create a sense of flow in my designs by repeating key elements such as shape, color, and pattern. This can be achieved through the use of:

Repetition: using the same elements multiple times

Radial Balance

Alternation: switching between two or more elements

Radial Balance

Progression: gradually increasing or decreasing a quality, such as size or color intensity

Radial Balance


Harmony in interior design is all about creating unity within a design by ensuring that all elements complement each other. I achieve this by repeating similar colors, textures, or shapes throughout a space and keeping the overall style consistent.


Incorporating contrast adds visual interest to a design. I create contrast by juxtaposing different elements, such as light and dark colors, smooth and rough textures, or large and small shapes. This helps to highlight important areas and create focal points.

Proportion and Scale

Proper proportion and scale are crucial for ensuring that objects and spaces look well-balanced and harmonious. I carefully consider the size of each element relative to others and the size of the space itself. This includes:

Relative Proportion

comparing the size of one element to another

interior design basics

Absolute Proportion

comparing the size of an element to a known standard or measurement

Rich fabrics, wood tones, and well-crafted furniture are fundamental elements in classic design. Often, I suggest incorporating ornate details, such as moldings, chandeliers, and elaborate window treatments, to create an elegant space.


Contemporary interior design is characterized by its simplicity and clean lines. This style is constantly evolving, reflecting the latest design trends and innovative materials. In my work, I often use neutral color palettes, smooth surfaces, and minimal decoration to underscore the contemporary aesthetic. Bold accent colors and geometric patterns can be effective in adding visual interest while maintaining the overall sleek appearance.


Eclectic design allows me to explore creativity by blending various design styles, color schemes, and textures to create a cohesive space. The key here lies in carefully curating elements from different periods and places, ensuring they complement one another. My strategy includes anchoring the room with a unifying color or theme while mixing and matching furniture, fabrics, and accessories to create a harmonious yet visually dynamic space.


When working with minimalist interior design, my focus lies in decluttering, optimizing space, and eliminating unnecessary elements. The minimalist approach is often defined by a neutral color palette, clean lines, and streamlined furniture to create an open, uncluttered space. By focusing on simple, functional items and avoiding excessive decoration, I can achieve a sense of serenity and calm in the environment. To prevent the space from becoming too stark, I sometimes introduce a few select accents, such as a piece of art or an eye-catching light fixture, for subtle visual interest.
