The Principles of Modern Interior Design

Kitchen Renovations Williamstown

If you’re thinking about redesigning your home, knowing the basics of modern interior design can help you to revitalise any space. While we all know the feeling of walking into a room and instantly falling in love with it, it can be hard to put your finger on exactly what makes a room work.

Whether you’re looking to undergo a complete kitchen renovation or simply want to refresh your interior design, these principles will help you create a home that is cohesive, stylish and timeless.


Creating a balance within a room is all about the visual weight of the shapes, textures, patterns, and colours being distributed in a way that creates a sense of equilibrium. There are two ways in which you can achieve this.

One is through symmetry, which is when a space is split into two sides that mirror one another. For example, having a coffee table in the middle of a living room with a couch and an armchair placed on both of its sides. This approach is easy and timeless, however, you may want to consider using some bold furniture and colours within the space to avoid it feeling unexciting and stuffy.

On the other hand, balance can be achieved by asymmetry as well. This way, the two sides of a room are balanced by shapes, colours and patterns which complement rather than mirror each other. Perhaps you could place a couch on one side of your coffee table with two armchairs on the other side, or have two different couches with different colours and styles.

Space and rhythm

Giving a room rhythm is all about repeating certain patterns and styles throughout a room,ensuring that it flows smoothly and makes sense to the eye. You can do this by choosing a certain colour or pattern and showering it throughout the space. For example, you may choose a painting with deep blue accents, and carry those blues throughout the room with pillows, lamps or vases.

However, when doing this it’s important that you spread it out across the room and avoid it looking cluttered and busy. It’s important to let a room breathe in certain areas so your eyes know where to look and what focal points are meant to be dominating the space.


Harmony is when every element of an interior works together and creates a unified style and aesthetic. While rhythm is all about creating little pops of drama, harmony is about creating a tranquil space that’s in complete understanding of itself.

Harmony can most commonly be achieved by using just a single colour throughout a room, but in different shades, textures and shapes to avoid a monotone or flat appearance.


Proper lighting is an integral part of any room and will make sure that every design feature you’ve chosen will be seen exactly how you want it to be seen. The type of lighting you’ll need depends on the room, as well as your own preferences. However, lighting should be stronger in some rooms than it is in others. For example, if you’re undergoing bathroom renovations, you’ll want to make sure you have bright lighting that comes from wall fixtures, which are ideal for styling and applying makeup.

Adding the ability to dim your lights will allow you to have complete control over the ambience and mood of the space. Lighting can also be used to emphasise certain objects and display them appropriately.

An anchor

Having an anchor or a centrepiece to a room will help to tie everything together and give the space a purpose. Whether that’s the view from the window, a fireplace, or a fabulous piece of art, using your furniture and decor to enhance and fully utilise your chosen anchor will complete any room.

Redesigning your home can be a big task, and ultimately there’s no right or wrong answer to what you should do. But following these principles will help keep you on track and ensure that the finished product is something that you’re proud of.
