Over the last couple of decades, photorealistic 3D rendering for interior design has unquestionably shaped the architecture and real estate industries.
In 2023 expert designers incorporate various 3D interior design rendering, interior animation concepts into their design workflow, marketing strategies and client presentations that combined increase their sales, and here’s why.
Interior renderings that look flawless, crisp, and perfect make it easy for designers to show potential clients what they have in mind.
So, 3D modeling software can help you build better relationships with your customers as well as improve your marketing.
Interior design is practically about bringing your customers’ visions and ideas to life.
If you have to take one thing from this blog post, these are the top four benefits in the table below:
Benefits of 3D rendering for Interior Design | How it can Improve Profits |
---|---|
Provides a realistic and accurate representation of the design | Helps clients envision the final product, reducing the need for revisions and changes, which can save time and money. |
Allows for easy collaboration and communication with clients and contractors | Improves the design process, leading to faster project completion and increased client satisfaction. |
Enables designers to experiment with different materials, colors, and textures | Increases the chances of creating a design that meets the client’s preferences and budget, leading to more successful projects and increased profits. |
Allows for virtual walkthroughs, fly-throughs, and virtual reality presentations | Enhances the client’s experience and increases the chances of closing the sale, leading to higher profits. |
Unfortunately, this wasn’t that easy in the past. Designers would take weeks or months sketching and building tiny models, primarily by hand. As you can imagine, this process was time-consuming, tedious, and expensive.
But with the arrival of 3D modeling professional software, things have changed for the better.
Let’s see how photorealistic rendering can foster your relationship with your customers and massively increase your profits.
What is 3D Rendering for Interior Design?
3D rendering for Interior Design is the process through which interior designers produce 3D images showcasing their design ideas.
The best thing with interior renderings is that they can offer a more realistic presentation of the item being displayed in an artistic way. Although there are a lot of tools that can be used in 3D rendering, this has not always been the case.
In the past, interior designers and other professionals used simple 2d drawings and sketches to display their products. The approach is very artistic, but you need to customize the project more quickly.
We’ve written more on how hand rendering look works.
While this may still be efficient in some instances, it is not best solution in a highly competitive market.

In other words, these “outdated” tools cannot be efficient where you need to stand out in the crowd or have the edge over your competitors.
With that in mind, the best way to present your designs and ideas to your existing and potential clients is through realistic rendering.
Why 3D Interior Design or Online Interior Design is gaining popularity?
3D interior design is essential to serving interior businesses and end-users.
Designers help their clients to understand their projects better by presenting the design via technical drawings and 3D designs, which makes the “sale” process more straightforward.
On the other side of the spectrum, a particular group of end-users with a limited budget or short time benefit from online interior designers, offering spatial solutions without going too into detail as with the standard design process.
Online interior designers work mainly with two tools to deliver the project, realistic rendering and mood board presentations.
In addition, the workflow is linked to retailers, where the end-user can place an order after project approval.
Is 3D rendering for interior design flexible?
Fundamentally, realistic 3D images are much more flexible than other processes or tools. For example, it can give you the flexibility of sharing product design and ideas with prospective clients even before beginning the actual design.
Here is a short animation made with Lumion (3D rendering software) showing how the detailing interior design can prevent problems as early stage, by dividing it into steps.

This is beneficial to all the stakeholders in the product design process. It allows them to bring together and share their ideas and interests, which is essential in the successful creation of the product.
Interior design renderings can make or break a project
Recently we have met 20 interior design specialists from different categories, doing different styles and even some freelancers.
Discussing some conducted project analysis done by TALLBOX in the past 12 months in regards to the studios which are using realistic rendering as part of their pipeline to execute their pre-design and presentation phases.
We came to the idea to split the conversation into two parts, to show the importance of 3d visuals as part of the process.
3D renderings for pre-design and presentation (best practices)
3D renderings and interior presentation
Everyone want’s to demonstrate their design ideas as quickly as possible to the client.
Not so bizarrely, the studios without a strategy and understanding how 3D renderings works, they end up overspending because of excessive amendments, time delays, and many more.
That includes even some studios which have in-house 3d teams.
The most common denominator scenarios are those when an interior visualizer gets involved too late, or the information passed onto him is not enough.
Digital and traditional presentations together
The key is Balance!
During the creative process most of the ideas are lost because of the constraints, which come with the traditional project approach used by 90 per cent of all designers.
Another significant flaw is being too digital or traditional with presentations.
Traditional design presentations
For those of you who rely on physical print, we all can agree that it’s an entirely different perspective. Most designers and architects would rather see their photos in a print which leaves the impression of a completed milestone.
Keep your traditional method of presentation and expand it with a digital version which is flexible and interactive.
Digital design presentations
Recently Samsung introduced their digital flipchart or whiteboard with the name Flip. Take a look at the video below.
Definitely this expands the capabilities for team collaborations, in-house meetings, brainstorm sessions and client presentations.
Imagine how convenient the client feel during the performance when you get the chance to update something whiteout having to make awkward pauses between flipping your computer screen.
Interactive images for interior design presentations
That is an additional feature we developed explicitly to supper interior design presentations.
Have a look at this article, if you curious how it can be a help: How Interactive CGI Images Will Change New Housing Developments?
3D renderings and pre-design concept
Designers often may lose the entire picture by being fussy with details. Let’s not forget that we all call the place where we live – home, not a showroom.
Often designers who haven’t implemented the 3D rendering system into their workflow, relying only on the traditional boards, charts and swatches. Stimulating conversations with clients are great, but one can lose that picture quite quickly without visual support.
Pre-design renderings provide the ability to explore multiple variations early into the creative process.
It saves time, therefore, budget and brings tons of value to the client by giving them adequately to understand from close how their un-build project will look.
Challenges while pre-designing interior spaces
There are delicate works, and then there are challenging ones. Sometimes, there are demanding clients and challenging circumstances. Spatial design is part of our lives for decades; therefore, it evolved, and today more than one pre-design process exist.
Interior renderings or interior illustration for pre-designing
We have done a lot of compelling concept presentations with deadlines of two to four days per room consisting of two design packages from scratch.
Then there are assignments where designers are still figuring out what will bring the best results with days while the time is ticking. All the imbalance with these projects came from the fact that we’re commissioned too late into the process.

Interior illustrations done by hand is excellent approach for pre-designing stages. The difference comes from the flexibility when compared to pre-design done with interior design program.
The 3D rendering method gets you quicker to the initial concept and can be amended easily.
Both methods are great for final presentations.
In this post we’ve explained how architecture and interior illustration works in-depth and how they compare to other methods.
How interior designers Improve Profits – the foundation?
Improving profits is achieved by utilizing each part of the business at its best. There are many ways to improve profits by using interior rendering.
Here are some of them.
Improving Customer Relationship
Customers are, without a doubt, the lifeblood of any business. Building a strong and lasting relationship with them is vital to the success of all companies.
In the world of interior designing, few things can actually make customers happier and satisfied than a hands-on, personalized experience. They always want to be sure that their projects and dreams mean the world to you as it does to them.

Interactive 3D models allow your customers to interract better with the details of the project. In this post, we’ve explained the five steps of our Interactive 3D Interior Visualization method in depth.
Through 3D rendering, you can give your clients the chance to see changes taking place right before their eyes. In fact, it can provide them with the ability to understand any changes within the interior design fully.
They won’t have to wait to be updated in scheduled meetings as this may take time.
It is safe to say that 3D rendering is a game-changer in the designing process, especially if your clients have difficulty visualizing colors and shapes; we’ve written more about this – Should you consider renders for your home design?
Design firms stay competitive only if they give their customers an unmatched design services experience. The return benefit comes as improved communication, increasing trust, and eradicating misunderstandings.
In essence, you’ll be offering your clients everything they need, so they’ll be willing to pay top dollar for the services.
If anything, they wouldn’t want to go anywhere else, which means increased sales and profits for your business constantly.
Photorealistic Interior Rendering Services is Easy and Affordable
Although many can argue that 3D / CAD floor plans are less hands-on than physical models, nothing can be further from the truth. Honestly speaking, computer-generated projects are way more comfortable and cheaper than physical models.
In this regard, you’ll be able to increase your mark-up’s by reducing the expenses incurred by using physical models and multiple mood boards.
3D Rendering can stimulate the Desired Emotional Response from Clients
The best way of eliciting an emotional response is by telling a story. This is precisely what 3D rendering can do to clients. 3D scenes are always designed and composed to make the viewers have an emotional attachment to the product.

Are you looking for interior renders?
Interior designers can use 3D rendering to make buildings look stylish, sleek and breathtaking. Designers can use 3D imagery to make a suburban house warm and comfortable, it can be used to make a restaurant look exotic and inviting and many more.
In short, 3D rendering can help describe a place and tell a story where words aren’t enough.
When is the Right Time to Use Photorealistic Renderings for an Interior Design Project?
Do you know what happens when a homeowner decides to hire an interior designer? We’ve have a comprehensive guide.
The first thing your potential client does is look at your portfolio and then at design prices.
The world of interior design is more about pictures and colors than anything else. It is important to choose a rendering that can dramatically increase the suitability of interior design, especially in the market. As an interior designer, you can use 3D rendering to pitch the project to the clients and sell an idea to the client, boosting your competitive advantage.
And since timing is essential, this infographic shows five major struggles that designers fight, all within tight timings of the projects.

Can be used to pitch a Project
Not too long ago, interior designers could only take portfolio photos after a building had been built and furnished. That’s no longer the case. With the use of quality renders home designs can reach marketing portfolios way before the project is finished.
And even if a client doesn’t approve the project, you can still use the designs to showcase your work to other clients. By pitching to potential clients, you can use these designs and ideas to increase your profits.
Creation of Fast Layouts
Like every other part of life, time is money in designing. In the past, designers had to schedule meetings with clients to showcase the project.
This was inconvenient given the busy schedules, but this is no longer true.
Thanks to the 3D CAD, you can now showcase 2d floor plans build as digital scale models in 3D.client for the work in progress and share ideas.
Different 3D interior design layouts
Presenting Final Projects to Investors
Selling a given project or design to clients is one thing, but selling the same project to investors is another thing.
Using 3D rendering to present your projects to investors is a crucial way to boost the business.
It can be used to accurately present projects to investors with an increased level of detail and dedication, which can be a game changer, especially if you’re looking for funds to boost your business.
What can 3D rendering software achieve for an Interior Design Project?
As a designer, you can visuals not just to boost your profits but also to decrease costs for the clients.
This can improve your relationship with the client and will enhance a smooth working process.
Interior 3d rendering can give clients a coherent picture of what you’re trying to present and will lead to fast approval. In other words, it can help tell a story in a very simple way that clients can easily understand.
What Problems can You Avoid by using 3D Renderings in the Interior Design Business?
3D interior rendering is fundamental in helping potential clients visualize themselves in the space even before it’s completed. As such, interior designers fully know that quality is critical to every project.
As a result, they often strive to create quality projects that are engaging and immersive.
But like with any part of bespoke design, mistakes can happen, and this can be pretty expensive to both the designer and the client, mainly if the error is detected at the final stages of the project.
Fortunately, such problems are no longer possible with 3D interior renderings. That’s because both the designer and the client can detect any mistake early on and rectify them accordingly.
For example, photo-realistic 3d representation can help detect problems with the layout of the design, color, and scheme. It can also answer questions or doubts raised by the client.
Benefits of Using AR (Augmented Reality) for Interior Designers
As interior designers, we all know that the best way to showcase a design is to see it in action. We can create beautiful renderings and 3D models, but nothing beats the experience of actually seeing a design come to life in a real-life setting.
That’s why Augmented Reality (AR) is becoming an increasingly popular tool for interior designers, allowing them to preview their designs in the context of the actual construction site.
Using AR, interior designers can virtually place their designs within a 3D space, allowing them to interact with the design and its environment in real-time.
This can help designers to visualize their ideas in a more realistic setting, allowing them to make any necessary adjustments before the design is set in stone.
It also allows designers to make sure that their designs will fit in with the existing architecture and infrastructure of the task site, helping to reduce costly mistakes.
AR also allows interior designers to be more interactive with their clients, providing them with a more immersive and engaging experience.
Clients can walk through the virtual space and experience a realistic representation of the final design, helping them to better understand the vision of the interior designer. This can help to ensure that the final design meets their expectations and help to reduce the chances of costly reworks.
It is the perfect tool for interior designers looking to showcase their designs in the actual construction site of the project with very engaging AR design pitch.
How 3D design software can shorten the Time for Interior Projects?
Genuinely speaking, interior designing is time-consuming. But because you don’t want to take shortcuts, using something that can reduce the time spent while still maintaining the quality of the project is an added advantage.
3D interior rendering is a great way to shorten this time.
Instead of creating a physical model, numerous mood boards for every design style. The countless showroom visits that can take weeks or even months.
3D rendering will take a couple of hours to complete different designs in high-quality.
It will eradicate revisions and reduce the risk of losing clients due to delays. Then spending a day or two in showrooms to solidify the choice becomes easy and satisfying for the client.
3D Interior Design Rendering – Creation Process
With 3D interior rendering, you can make the process straightforward, as shown below.
· Client Supplies Documents – This is the first stage of the entire process. First, you look at the ideas supplied by the client and chip in with ideas that would suit the client’s project.
· Modeling, Geometry, and Camera Selections – This stage involves rendering the preview scenes of the projects that should be sent to the client for review (layouts and clay models). In addition, this stage includes using cameras to take the client through the entire or part of the model and how it should look in real life.
· Execution of the Model – This stage is the actual model creation that should be sent to the client for approval. It involves a lot of coordination and the use of various materials, such as refined lighting. This stage can only be considered complete if the client is satisfied and verifies the accuracy of the entire project.
· Final Stage and Production – At this stage, the 3D designer renders the scene created above by including everything, including furniture, furnishing, and decorations. The process can be considered a success if the client is satisfied and approves the project.
· Post Processing – This stage includes post-processing features such as skies and background. It can also include color adjustments and, of course, delivery to the client.
Can photorealistic interior rendering be used in small or large Interior Design Projects?
Building a strong team is vital for any design company. Particularly important for startups, the success of every project depends on every project.
The design itself it’s a small part of the whole game.
We’ve explained in-depth how to develop a design team in this post.
3D interior rendering not only gives you control over the project but also increases flexibility.
This is because there are no limit constraints in the sense that it can be used for both large and small interior design 3D projects.
What type of Interior Design studios can improve profit with 3D visualization?
Regardless of the interior studio, scope, or purpose (residential or commercial), 3D renderings can work equally well for all. The only difference will be the workflow and the stage of each project.
A small team or team of one means something other than inefficiency. For example, small design teams can effectively produce better quality projects in the short term for different tasks, increasing interest quality.
In most cases, small design studios rely on easy-to-use software to produce interior renderings in 3D, which are only sometimes the best option to match the quality of the service.
Furthermore, in teams of two to three designers, one or two often are multidisciplinary with some experience in 3D and CAD software doing diverse operations. As a result, this is where precisely the inefficiency and loss of profits come from.
The only negative side of the small team studios is the tenuous connection between more extended period interior projects and the profits of the design studio. The longer the project is, the less profit.
This is where 3D Renderings can improve the internal system by cutting the times in half for all decision-making moments. In another writing, we have explained how we have improved the efficiency and profits for interior designers.
At that stage, when the team of designers is above 5 to 10 experts with different tasks, flexibility is still achieved with the difference in the scale of the operations. On average, studios of 10 people work on 5 to 12 projects simultaneously.
Having that many projects under one of two decision-makers (principal interior designers) mean they must make a considerable amount of important decisions in a short amount of time, all with the client’s consent.
Each stage of an interior project ends with presentations, and each sub-stage is followed by an introduction (online or offline).
Typically in mid-size interior studios, one or two positions will be dedicated to the in-house renderers.
The issue with that is the constant flow of projects and deadlines, will strain the 3D team within the studio over time.
One renderer can deal with up to two or three projects without decreasing the quality = loss in profit, or longer lead times.
Where there is a high profit, there is always an increased risk of failure or loss.
We’ve designed our 3D interior rendering services to eliminate the potential failure when dealing with more than two projects at a time within an interior design studio. Implementing visualization services workflow will:
- shorten the time for the client’s presentations
- provide detailed visual images for each stage of a project
- used as marketing for future purposes and new clients
With large organizations or studios with designers and other experts (more than ten people), an entire culture represents a complex of beliefs, ideas, assumptions, values, and attitudes that the members of the working team share.
Ideally, these large teams will manage to deal with more projects simultaneously, keeping the service quality high.
Typically, studios have an in-house 3D team that will always be busy servicing different units on different projects.
As with every large business, more in-house professionals mean increased expenses, and the more the group size increases, the more cooperation among group members decreases. This is where profits and efficiency can be improved.
One of the ways to overcome that bottleneck of lost efficiency and profits over the specific project is to outsource a project/s to an external Interior Design CGI company like TALLBOX.
We have experienced team and systems to run in parallel supporting with concept renderings, mood boards, and preliminary 3D elevation views and layouts.
Best practices for Interior stylists and Interior decorators
Interior styling is an as complicated job as much as interior design.
Stylist’s clients may vary from photographers, homeowners, magazines, catalogs, and PR agencies.
Often curating an interior made by somebody else is even more tricky than creating the interior project at first instance. An interior stylist’s job should not be confused with what interior designers do; they are two very different activities.
As a very diverse profession, interior stylists work with mood boards, sketches, and SketchUp to demonstrate their ideas and concepts.
Therefore, implementing any type of rendering is a logical step that will improve communication and turnaround time.
What makes 3D interior design renderings important?
One of the main advantages of 3D designs is to free up time for the stylist to manage the set building activities, photographers, logistics, and assistants.
Having more time to plan to communicate the execution of the styling set is an essential part. The better organization, the quicker, more predictable, and profitable the work will be.
How much do 3D interior desigenrs cost to hire?
Costs to hire as in-house team
To hire a 3D interior designer in a developed country typically cost between £90 ($125) and £150 ($205) for a beginner to an average skilled designer and £200 ($270) to £400+ ($540) per day for average to expert level skilled 3D designer. Assuming that is on a monthly basis contract.
If you decide to take down the route of per project / per day add 30% on top of the above figures and you might be on the correct side.
Hiring 3D designers in your in-house team is a good idea only if you know and have a setup workflow.
The costs to hire them per day might spiral out of control as they will spend more time organizing the project files, refining design concepts and other time-consuming tasks instead of focusing on building the project.
Additionally to hire a 3D interior designer you will need to provide the necessary equipment along with all software unless they bring their own PC configuration with them; which might lead to an even higher cost to hire.
Costs to hire on a freelance basis
It is the cheaper option but will require more managing skills.
In a developed country 3D interior freelancers charge per project, per hour and sometimes per image.
If your strategy is to hire them per hour, expect between £60 ($81) and £110 ($150) for a beginner to an average skilled designer and £170 ($230) to £340+ ($460) per day for average to expert level skilled 3D designer.
Assuming that you will have the concept of the project ready and some BIM information, too.
In case your concept it’s not refined, and there will be some back and forth, expect an additional 20% to 30% on top.
With this option, you’re saving from equipment, software and salary – tax payment, but it will consume more time to manage and explain information.
Interior renderings as Plan B as a no brainer?
Often things could go wrong with interior styling.
The however organized person you are, there are things which we can’t control. Usually, essential furniture or decors doesn’t arrive on time, and this is where Plan B comes at play.
Always prepare a second back up option; it is a rule of thumb, which we at TALLBOX give as advice to the interior stylists we partner with.
Altering the project in 3D to a second option is 70 percent quicker in comparison to the first option since most of the internal environment and models are built.
3D rendering is a term which describes the process of a computer calculating 3D information from a 3D scene which consists of polygons, textures and lighting and calculating the final result into a 2D image.
The output is called a 3D rendered image or Computer generated image. When there is a series of pictures rendered & compiled together, the result is an animation.
3D animation is usually the very final phase of the creation of 3D scenes.
If your goal is to render an animation, you should render a sequence of 3D pictures and export to a video file or video production software which is capable of stitching them into an animation.
Twenty-four renderings create 1 second of animation.
Typically each project should be supported by detailed specifications and drawings, to be built as close to reality as possible.
Most typical file types are that could be exported from applications such as Autocad (.cad), Revit (.rvt; .fbx), Archicad (.ifc, .obj; .dgn; .stl), SketchUp Pro (.skp; .3ds; .obj) or any other blueprint capable software.
If in case you work in a software that is not common, there are converter applications that would allow us to convert your files to appropriate ones for us to use.
Additionally, we will be happy if we are provided with mood boards, excel specifications, or pdf with any additional information or guidance for the project.
Sure we can. A brief explanation, comment, and even a scribble would do.
At some cases, a detailed 3D rendering images are needed for the client to make sure we’re on the right track. But this has to proceed with caution, as it may add additional time for the final submission of the project.
Each detailing of an image (post-production or 3D detailing) takes extra time and effort for your 3D artist).
This is something that we should be aware of since the beginning of the project.
Typically it is possible for us to tweak the 3D renderings to more artistic stylization if you ask us to do so. This depends again on the complexity and time we have got dedicated to the project.
If we’re approaching the set deadline set in the beginning of the project. We should consider and plan a new timing.
Among the most used software for 3D rendering is 3Ds Max, a design tool made by Autodesk

Interior rendering example project
With this project, TALLBOX’s team was approached by the architectural practice to help with the 3D renderings and spatial design concept proposals.
By getting as early as a possible 3D interior design team with the project, the architects made it possible to demonstrate the project in its best lights by offering a wide variety of communication renderings.
interior rendering – concept phases
Below is the final interior rendering which showcases the materials, details and light which were chosen by the architects and their client.


The project was about a house conversion of Mid-Century to a contemporary hyper-luxury home for a family of five.
In little over 3 months, it went from Mid-Century house with typical architectural details for that period to a modern contemporary style.
With preserved references to the past, along with some external amenities (incl. front and back gardens).
This guide for 3D rendering, Interior Design and Profits had the simple idea to inform interior designers that there are ways to increase profits by working smart, not hard.
