Designing the Future: 3D Rendering in Interior Design

As an interior designer, you want to keep up with the competition, remain updated on the latest industry innovations, and offer your clients the best services possible. One way to do all those things is by incorporating 3D renderings into your design process.

Modern visualization techniques like 3D rendering have revolutionized how we design, build, and sell real estate. Whether you’re presenting initial concepts, iterating previously approved designs, or showcasing your work to the public, 3D rendering is an optimal way to impress clients and position yourself as a forward-thinking designer.

In this article, we explore the relevance of 3D rendering in interior design, including its benefits, the types of interior design rendering, and the latest trends you need to know about.

What Is 3D Interior Design Rendering?

A 3D interior design rendering is a scale drawing of a design. Professional renderers create hyperrealistic versions of existing or imagined spaces using 3D modeling and visualization programs. They take into account information provided by the designer, including the dimensions, layout, lighting, furniture, materials, and more. 

This results in a simulated environment that accurately depicts how a space would look down to its smallest details. You can use it to showcase how much natural light a room will have, how the space flows, how it will look from different angles, and other features you want to highlight.

Visuals can help stakeholders get on the same page. It can encourage buy-in from skeptical clients, help coordinate expectations with various contractors, offer a comprehensive overview of the project, and more. 

Photorealistic renderings allow architects, interior designers, and clients appreciate what the end product would look like more quickly, cost efficiently, and with less effort.

Benefits of 3D Interior Design Rendering

Global Market Insights reported that the 3D rendering market was worth over $3 billion in 2022. It has continued to grow at an encouraging rate, highlighting its relevance in real estate, including interior design.

Why has it become so widespread? Let’s examine its many benefits in the field.

Saves Time and Money

From proposing projects to creating iterations, 3D renderings are cheaper to work with. 

Discriminating clients with several modification requests are easier to satisfy since 3D renderings in interior design are easier and faster to edit than traditional drawings. Instead of starting from scratch, you can simply ask Plus Render to perform certain changes or come up with a few alternative models that you can present to your client. 

Professional renderers like Plus Render give their clients a certain number of acceptable revisions so the cost of changes is often built into the initial cost.

In addition, renderings help you save on costly mistakes during renovations. During meetings, you can present your ideas to your contractors and show them the renderings. This can help them raise important points or questions while avoiding rework that would entail wasting time, materials, and money.

Design Accuracy 

While sketches show off your artistic ability, they may not depict your vision as accurately as you need to. In contrast, 3D renderings enable realistic, precise, and accurate designs. Thanks to the many software tools available, your 3D renderings will show exactly what you want—even the minutest details, like contrasting textures, light, and materials. 

This also ensures your vision matches the results. Conversations can sometimes lead to miscommunication. However, 3D renderings can significantly minimize misunderstanding. It helps you communicate your vision with your team and to the client. 

Makes You Stand Out

Many clients prefer to work with designers who have impressive portfolios. In this day and age, that often means including renderings that highlight virtual and actual designs. If you want to showcase your expertise in certain aesthetics or spaces, you can put together a portfolio that features those types of designs. 

Renderings speak volumes and are more convincing than several lines of text describing your capabilities. So, if you want to stand out, show the world what you can do. Words are good but renderings are exceptionally compelling. 

Encourages Client Engagement

Clients may feel alienated by blueprints with technical jargon. They have a lot of details and elements that aren’t understandable to the general public.

But who wouldn’t feel engaged by a beautifully rendered space that looks extremely real? 

When you use renderings, it puts you and your client on an even footing. You both know what you’re looking at and it isn’t hard to understand. They can then more confidently ask questions, suggest changes, or express preferences for the final design.

Enhances Communication With Contractors

Getting your design approved by the client is only the first step. Once you have their approval, it’s up to the designers to make those ideas a reality. This necessitates communicating with carpenters, electricians, flooring specialists, and builders. 

Coordination is a huge task but it can be made easier with renderings. Since you can show them how the final result is supposed to look, they have a clearer idea of what they need to accomplish. It minimizes discussions as well as lengthy back and forths which can become tedious and taxing.

Lets You Address Issues Early On

Any design flaws or issues can mean serious rework and lost time, especially if renovation has begun. 3D renderings let you spot areas of concern during the design phase before considerable effort has been exerted. 

Aside from saving on unnecessary expenses, renderings allow you to deliver on time and within budget, strengthening your reputation as a reliable designer.

Lets You Experiment With Different Aesthetics

As an artist, you may want to flex your creative muscles and experiment with different types of interior spaces from time to time. Renderings allow you to breathe life into avant-garde designs, play around with materials you haven’t worked with, or test layouts that are less popular with the masses. 

You don’t have to find a client to sign up for your ideas straightaway. You can experiment and test your creative limits without turning them into real-life spaces. You can let your imagination run free because anything is possible with renderings.

Types of Interior Design Rendering

With visualization technology that’s virtually limitless, there are many types of interior design renderings available to you. Let’s take a look at some of the most popular.

Line Drawings or Sketches

Line drawings or sketches are simple representations of a designer’s ideas. These black and white sketches feature clean vertical, horizontal, diagonal, zigzag, and curved lines. Although some may add colors, traditional line drawings are black and white. 

These sketches, as one might imagine, don’t convey textures, light, and other minute details; however, they are sufficient for communicating the idea behind a design. 


A maquette is a scale-to-size model of what the final project would look like. It is used to determine the materials and final results of a project. These were popular once upon a time; however, people have switched to digital designs as they are easier to make than physical models. 

Photorealistic Rendering 

A photorealistic rendering is a life-like picture of what the final project would look like. Simply put, it is a picture of what a client’s space would look like after it has been redesigned. It is realistic and perfectly captures details that a sketch isn’t able to. That said, 2D renderings cannot capture spatial concepts well. 

3D Renderings 

3D renderings in interior design are immersive experiences. They capture the space along with textures, lighting, and more. These are highly realistic, so they empower clients to envision exactly what the final space will look like. 

Plus Render specializes in 3D renderings and other visualization tools. We combine our technical expertise with cutting-edge technology to deliver high-precision and realistic 3D renderings. Viewers feel like they’re inside the space. We also deliver immersive external and aerial renderings depending on which part of your project you want to highlight.

Video Rendering

Video renderings are making their mark in interior design. These provide detailed shots of the location and key information that would have otherwise been omitted in a picture. Instead of still pictures, video rendering employs movement so the viewer feels like they’re navigating the space from within and experiencing it firsthand. This type of rendering is quite often employed as a virtual tour.

Our clients typically employ a combination of photorealistic rendering, 3D rendering, virtual tours, and video rendering to market their real estate developments. Because of their immensely realistic qualities, they help generate quality leads and encourage clients to seal the deal, even without in-person visits or elaborate open houses.

You don’t have to follow interior design trends but it’s always good to know about them. Here are some of the design trends we’re seeing this year:

Sustainable Designs

Fast furniture is out and sustainable designs are in. Trendy aesthetics incorporate energy-efficient designs and sustainable materials like bamboo, reclaimed wood, and cork.

Biophilic Designs

Embrace the outdoors inside! Nowadays, organic shapes, natural light, and spaces that feel like an extension of the outdoors are incredibly popular.

Versatile Spaces

How about a bedroom that can also be used as a home office? Or a library that doubles as a game room? People are loving multi-functional spaces that can be used in a variety of ways.

Smart Homes

From remote-controlled heating and cooling to smart door locks, the Internet of Things is well and truly here. Consider adding smart appliances and home automation systems to win points among modern homeowners.
