A 3D interior room design is defined as the representation of a fully-furnished and fully-decorated room from a three-dimensional perspective with a focus on the most important elements.

You can achieve this by using 3D interior design software. This helps interior designers sell their ideas better since they can reassure and convince their clients. A three-dimensional room design presents the selected area with text/visual information, but the media/formats into which the information is integrated can vary drastically. The most common use cases are floor plans, graphic presentations, room configurators, room visualisations, and walkthrough tours. The best thing about it is that it can be updated and modified over time. 

Let’s dive into 7 ways a 3D room design can help you realise a beautiful design vision for your dream home, whether you are making it from scratch or just renovating it. You can personalise it according to your needs. 

A. Incorporate Lighting Into Your 3D Room Design

Light is the thread that paints the visual experiences of the room. Wondering how you can incorporate lighting into the three-dimensional room design to bring the art to life? You can do that by using artificial, natural, or a mix of both. Natural lighting helps improve air quality, promotes good health and productivity, reduces energy costs, and brightens dark rooms. Artificial lighting also comes from light fixtures, bulbs and lamps which accentuate certain areas/objects, and you can have more control over the brightness levels to reduce eye strain. 

The brightness, depth and shadows created by the light must be appropriately adjusted to make the visual representation look natural, accurate, realistic and more convincing. Lighting can help you breathe more life into those computer-generated 3D room design images by:

  • It helps you set the right mood of the room by adjusting the direction of the beam speed and colour temperature. 
  • It introduces a natural glow into the room and distinguishes the different materials of the objects.  
  • It helps showcase different design zones, enhancing a room’s functionality and efficiency.
  • It adds realism through shadows and communicates the look, feel and personality of a home. 
  • It highlights the key elements by drawing attention towards the best parts of the room and away from the less polished parts.

B. Choose the Right Colours for Your 3D Room Design 

Colour has a major impact on how a certain room is defined. It affects human perception and emotion to a large extent. There are five categories of colour schemes that interior designers play around with to arrive at the most thoughtful 3D room colour design: 

(1) Light Colours (relies less on textural contrast since it is reflective)

(2) Dark Colours (rely more on textural contrast | complement with plenty of natural light to create visual interest)  

(3) Neutrals (safe choice | blends well with any contrasting colour/tactile texture | easier to live with | timeless vibe)

(4) Complementary Colours (colours located at the opposite ends of the colour wheel – one subtle & one dominant)

(5) Monochromatic Colours (one primary colour complemented by all its hues and shades)

An interior colour palette is a meticulous selection and strategic placement of colours that help dictate people’s influence and experience in that home. It flows through the house connecting each room on its way to create an eye-catching and stunning visual language, and it also adds a fresh perspective for the onlookers. Start with the most commonly used areas, move towards the transition areas (~areas that are often neglected) and bring them into the narrative when you plan the interior colour scheme.

C. Pick the Right Materials & Textures for Your 3D Room Design 

Apply appropriate materials to the furniture and tapestry in the room to quickly set the mood of the space. Remember that texture also affects how colour absorbs and reflects light from the surface. Rough fabrics absorb more light and make a colour look warm, while glossy, shiny fabrics reflect the light and appear lighter. Layering textures, patterns and materials are key to creating visual depth, dimension and an interesting character to the space. ‍

D. The Size & Placement of Objects In a 3D Room Design Is Also Significant

Arrange the room structure and its objects symmetrically to evoke a more pleasant subconscious reaction when you see it. A ‘balance’ in interior design is defined as an equal visual weight distribution through a certain space, which must be perfectly maintained. There are three types of balance in interior design:

  • Asymmetrical Balance (different objects with the same visual weight which affect the eyes in a similar way)
  • Symmetrical Balance (same objects in similar positions located on both sides of the vertical for uniform view)
  • Radial Balance (arraying all vital design elements around a certain centre point that is previously determined)

E. The Scale & Proportion of Furniture & Decor in a 3D Room Design

3D room design helps you to get an eye-level view of what it is like to experience the room. You can select key vantage points and ensure that the design elements articulate your vision properly at these points without compromising the design’s composition from all other perspectives. 

The ‘scale’ is focused on how objects are sized compared to one another. It is a more specific concept. The ‘proportion’ deals with the ratio of a single element or two elements to the whole design. It is a more relative concept. Understanding the scale and proportion of objects allows interior designers to factor in the functionality and aesthetics of the room and give it a more cohesive structure.

There are different types of proportions in interior design:

  • Space Proportion 
  • Colour Proportion
  • Shape Proportion
  • Light proportion

F. The Principle of Contrast and Repetition in 3D Room Design

  • Contrast – To create an interesting contrast, put two different design elements against each other, be it wall colour or different geometric structures (~circles, squares).  
  • Repetition – Use the same element (textures, colours, patterns) multiple times within a certain space to create a symmetrical balance.

G. Transition, Progression & Circulation of Elements to Design a More Functional 3D Room 

Transition – Outline clear differences that are instantly noticeable to the naked eye and create a smooth visual flow. 

Progression – Take a base element and increase/decrease its qualities through size gradation while preserving its foundation. 

Circulation – Aim for easy circulation in the three-dimensional room design by ensuring the distance between structures is comfortable enough to work around and walk through.

FAQs On 3D Room Design

How to Make a 3D Room Design?
There are multiple ways in which you can make a 3D room design and you can use them single-handedly and in a combination too:

  • 3D Rendering
  • 3D Modelling
  • Animation

What’s the Difference Between 2D Room Design and 3D Room Design?
A 2D room design refers to a simple flat drawing of the room, which indicates the location of walls and fixtures (windows/doors) without any reference to the height or depth. A 3D room design refers to a three-dimensional layout (height, length, breadth) that offers a detailed and realistic explanation of the space and its elements.

What Are the Benefits of a 3D Room Design?

  • It helps in a more holistic and accurate visualisation of the entire finished space even before construction/renovation starts. You can closely examine the technical aspects and the aesthetic benefits as well.
  • It minimises unnecessary time, effort and costs spent on ‘redos’ in the actual project as it indicates any mistakes beforehand and helps you modify the design accordingly. It prevents you from potential design disasters.
  • It offers you the flexibility of exploring multiple possibilities and trying out multiple design permutations for your space without physically moving or touching even a single element at no cost.
  • It allows the architectural drawings to be reconfigured and modified in real-time. It also helps you save duplicates/two different versions of the room design so that you can track the changes made.
  • It helps the interior designer develop a more adaptable and customisable approach when showcasing their design ideas to the clients, thereby enhancing the project’s impact.
