You can include furniture symbols and colors for each room, display measurements and surface areas, and even make multiple 3D renderings of the same room from different perspectives.

3D visualizations

For a realistic preview of what a project will look like, 3D renderings are super helpful because they eliminate the guesswork and imagination that is often needed to sell the value of an interior design project.

When creating visuals for clients, it's important to have a good selection of home decorations to enhance the mockup and make it as realistic as possible.

Cedreo lets you pick from over 7,000 pieces of furniture, decorations, and materials available to customize the interior and exterior of any home design.

Roomeon is a feature-rich 3D interior design software that provides a good amount of options for objects to design with and has a neat rotating feature to provide a 360 viewing experience for your clients. You have the option of three viewing cameras: person camera, 3D camera, and satellite camera.

Roomeon also has a feature to customize the lighting in different rooms, known as the “Create the Mood'' feature. This is useful for simulating how different times of the day affect your design. The app is easy to use, minimizing the learning curve.

Key interior design features:

SmartDraw is an online-based design tool that can be used to create 2D floor plans and diagrams. You can access the tool on your computer, phone, or tablet, letting you take your work to-go.

While SmartDraw is a handy tool to draft up 2D models, it doesn’t offer 3D rendering or modeling. This is a drawback as most people want to see exactly what their house is going to look like.

SmartDraw is an inexpensive tool and easy to use, though, making it a good starting choice for the beginner designer or small teams of up to 5 people.

Key interior design features:

  • 2D rendering
  • Inexpensive
  • Easy to use

Planner 5D is one of the most popular interior design rendering solutions on this list. It can create both 2D floor plans and 3D renderings and offers a wide range of design tools. It can be accessed from mobile devices as well as your computer, making it easy to access your design ideas no matter where you are.

Planner 5D is free to use for simple floor plans and interior designs, but the ability to create photorealistic 3D rendering does come at an additional cost—and depending on how many designs you’re putting out a month, this cost can add up. This generally makes it a better option for architects than interior designers.

In short, if you’re looking for the basics, this is a solid free option. However, keep in mind that the 3D rendering quality is fairly poor compared to other platforms. If the quality and presentation of your designs is really important to you, it might make sense to look at another more robust option like Cedreo.

Key interior design features:

  • 2D rendering available for free
  • 3D rendering available at a premium
  • Mobile-friendly

5. Ivy

Screenshot home page Ivy

Ivy is an interior designing tool created by Houzz . It’s easy to use, making it a good program for both novices and industry veterans. The app does not allow designers to create floor plans or generate 3D visualizations of a room.

The most unique feature about Ivy is the ability to connect directly to clients, letting you upload your design ideas and share them in real-time. The client can then approve or disapprove the different components of your design right in the app. This saves both of you time and tracks any changes.

Ivy is one of the pricier apps on this list, but the most expensive tier also includes other useful features like payment and business management tools, potentially replacing other apps you may be paying for separately.

The downsides to Ivy are that it doesn’t have a very wide feature set and licensing can be a nuisance. As a result, if you’re designing your own home or flipping homes for profit, this may not be the tool for you. If you’re working on larger, higher-scale projects, however, this could be great.

Key interior design features:

  • Easy to use
  • Ability to connect with your clients directly through the app
  • Designed for large businesses

Infurnia is another solid interior design tool. It’s a feature-rich platform specially made for interior designers.

With Infurnia, you can create 2D drawings and floor plans as well as photorealistic 3D, panoramic, and VR renderings. It also provides a space to collaborate in real-time, similar to Google Docs, making it a powerful tool for teams of multiple designers.

Lastly, it has a large catalog of furniture, floorings, wall coverings, customizable staircases, and modular kitchen tools for every design need.

Key interior design features:

  • Cloud-based platform
  • Supports both 2D and 3D renderings

Live Home 3D is a home design software to help even the novice designer create detailed 2D floor plans and 3D renderings quickly and easily.

Like the other tools on this list, Live Home 3D lets you plan out the layout and furnishings of a single room or an entire house. Compatible with both Mac and Windows, this program works on all your devices and enables you to pick up where you left off, no matter where you’re working.

Simply draw your 2D floor plan, render it into 3D to get a more realistic look at the environment, and build out the interior. You can even shoot interior movies and export your designs to 360 panoramas, stereo 3D videos, 360 videos, and stereo 3D 360 video.

Roomstyler (formerly known as Mydeco) is an intuitive home design app that helps you design rooms from scratch. You can choose from a library of preloaded room layouts or come up with your own with easy drag-and-drop options of walls, windows, and more. Your changes will instantly be reflected in both 2D and 3D and can be viewed from any angle.

Like most of the other programs on this list, Roomstyler gives you the option to customize coverings in terms of colors, sizes, and placement. It also offers the option to furnish the interior with products from real-life brands including IKEA, John Lewis, Moooi, and Marcel Wanders, among others. This helps both you and your client better imagine exactly how the design will look once the project is completed, down to the last appliance and piece of furniture.

The app is relatively easy to pick up, but Roomstyler does offer a playlist of tutorial videos that you can watch in case there's anything you're unsure of. The program is online-based so you don't need to download a desktop app or take up valuable room on your hard drive to use it.

Key interior design features:

  • Library of room templates and customizable coverings
  • Supports both 2D and 3D rendering
  • Furnishings from real-life brands
Screenshot home page sweet home 3D

Sweet Home 3D works much like many of the other tools on this list. You begin by drawing a 2D room layout, add walls, and drag and drop objects like doors, windows, and furniture. Edit the colors and sizes of objects to best fit your space.

Once you’re happy with your design, you can take a virtual 3D tour to make sure you didn't miss anything and get a holistic view of your design before presenting it to your client. You can also take photos and videos during the virtual 3D tour.

A unique thing about Sweet Home 3D is you can draw irregular wall shapes rather than conforming to straight lines—it’s all about total creative freedom. You also have the ability to see simulated 3D visuals in real-time when you make changes to the 2D plan.

Key interior design features:

  • Supports both 2D and 3D rendering
  • Virtual 3D tour capability
  • Ability to draw irregular wall shapes
Screenshot home page Design a room

Design a Room by Armstrong Flooring is a great app to use if you’re redesigning an existing room or home rather than creating one from scratch. That’s because this app works by having you upload a photo of your existing room or select a photo from hundreds of available templates.

From there, you can edit the room by customizing the flooring, wall paint, and stain of the furniture. Unfortunately, the design options are pretty limited after that, which is why we recommend it as a tool for personal use or for making minor changes to your existing space.

Key interior design features:

  • Ability to upload a photo of an existing room
  • Customize the flooring, wall paint, and stain of furniture

Which Interior Design Software is Right for Your Business?
