Before You Get Started

Assessing Your Spaces and Creating a Plan

Take a critical look at your spaces and identify their strengths and weaknesses. Consider how you currently use the space and what changes you want to make. Create a detailed plan outlining your goals, including each room’s desired functionality and aesthetic.

Take measurements where needed and analyse possibilities with existing furniture and fixtures, as well as your traffic flow. Remember to reevaluate your needs and consider any limitations you might have with the spaces you have.

Setting a Budget

Before embarking on any interior design project, it is essential to set a realistic budget. Consider how much you will invest in your home, including furniture, decor, and any necessary renovations.

Remember to define your project scope, set priorities, and allocate funds accordingly. Research the true cost of interior design in your area and obtain quotes for work you’ll need to get done. Also, make sure to have funds for unforeseen expenses that may arise along the way too.

Defining Your Style

A clear vision of your style is crucial for a cohesive and harmonious interior design. Explore different design styles and determine what resonates with you the most. You can already look for inspiration in magazines or by visiting local design showrooms, but we will discuss this more below. Pay attention to colour palettes, textures, and furniture styles that appeal to you, and incorporate them into your overall design concept. Defining your style early on will help with many of the crucial decisions moving forward.

You can develop a concept you'll follow based on your goals, preferences, and budget. Don't go overboard, and always keep your lifestyle in mind with the comfort and functionality you aim for. Try to be realistic and align the three factors above before moving on.

Big Decisions To Make


Choosing the right colours is fundamental in interior design, as the colour scheme can significantly impact the atmosphere of a space. Consider the existing architectural elements, such as flooring and wall finishes, and select a colour scheme that complements these elements while reflecting your style. 

It’s important to consider colour psychology, but you can experiment with neutrals as a base and different hues, tones, and textures to create depth and visual interest within your space. Remember the purposes your rooms will have and test your choices before committing. 


Proper lighting is crucial in creating ambience and functionality within a room. Incorporate natural and artificial lighting sources to enhance the atmosphere with your colour palette in mind. Use a mix of task, ambient, and accent lighting to highlight specific features and cater to different activities.


Integrating patterns into your design adds personality and visual appeal to your space. Mix and match different patterns, such as stripes, florals, geometric shapes, or abstract designs, while ensuring they harmonise with your style and chosen colour palette. Consider the scale of patterns and use them strategically to create balance.


Selecting the right furniture is vital to achieving a comfortable and functional interior. Determine the specific needs of each room and choose furniture pieces that fulfil those requirements.

Consider the scale and proportion of each item to the room’s size and layout. Invest in quality pieces that stand the test of time, and always prioritise comfort that fits your selected style perfectly.

Many of these decisions may prove difficult even when you've covered the initial considerations. This may be the perfect time to consult a professional, where experience and valuable input they offer comes as one of the major benefits of hiring an interior designer vs doing it yourself.

Techniques To Get It Done


Layering is a widespread technique where you incorporate different elements, such as textures, colours, and patterns we listed above, adding depth and dimension to your space. You can experiment with different materials and furniture placement to create visual interest and tactile appeal. You can add layers with accessories, window treatments, and artwork too.

Balance and Proportion

Achieving balance and proportion is essential for a well-designed space. With such an approach, you distribute visual weight evenly throughout the room to create a sense of equilibrium. Balance can be achieved through symmetrical or asymmetrical arrangements, depending on your style.

Focal Points

Creating a focal point within a room helps draw attention and adds visual interest. Identify a key feature in each space, such as a fireplace, an accent wall, or a statement piece of furniture, and highlight it to serve as the focal point. Arrange other elements around it to create a cohesive, appealing design.

Rhyme and Repeat

Incorporating elements of rhyme and repeat in your design adds a sense of harmony and unity. Just as you would when choosing the right exterior design for your home, you repeat certain colours, patterns, or materials throughout the space to create a cohesive look. 

Use repetition strategically to guide the eye and create a sense of rhythm within the room. This technique can be applied to furniture, accessories, and architectural details. Still, it should all point in the same direction in search of visual appeal. 

You can ultimately mix and match the design styles and trends, but you should always stick to the techniques as you create a unique space. You want to avoid visual overwhelm, and this is a sure way to do it.

Where to Get Inspiration

Sustainable Design

With an increasing focus on environmental consciousness, sustainable design is a prominent trend in Australian interiors nowadays. Consider incorporating eco-friendly materials, energy-efficient lighting, and water-saving fixtures into your design. 

Look for furniture and decor made from recycled or renewable materials but keep a specific style in mind while you’re at it. Embrace sustainable practices to reduce your carbon footprint as you create a stylish and eco-conscious home.


The minimalist design movement continues to inspire many homeowners. The prominent features will be clean lines, open spaces, and a clutter-free environment. Opt for functional furniture and prioritise quality over quantity. 

The style is characterised by simplicity, so you will not need many pieces of furniture, or accessories for that matter. However, remember you’ll need innovative storage solutions to keep belongings out of sight and maintain a serene atmosphere.

Smart Home Tech

Incorporating smart home technology into your interior design can enhance convenience, efficiency, and connectivity. Consider integrating voice-controlled devices, automated lighting systems, and smart thermostats into your home. Embrace technology that seamlessly blends with your design aesthetic while providing added comfort and control.

Smart tech has largely influenced both minimalism and sustainable design, opening up new possibilities and shaping how modern families live. Its improved commodity makes smart home tech a sensible solution for many lifestyle woes you might have. 

Learning from Neighbors

Drawing inspiration from your neighbours and local community is an excellent way to stay attuned to regional design trends. Take a stroll around your neighbourhood, visit open houses, or attend local design events. Observe the choices and unique features of nearby homes to gain ideas and inspiration relevant to you.

If you have a specific area like Sydney in mind, browse online and find the top 10 Sydney suburbs for interior design inspiration first. Don’t copy what others have done, but a simple visit to an open house there may help you get over your creative block.
