Impress your future interior design clients and clearly express your design ideas by creating beautiful, compelling 3D floor plans. This guide will cover why 3D floor plans matter for your business, the elements to include in your plan, steps for how to make 3D floor plans, options to consider for interior design floor plan software and more.

What is a 3D floor plan and why are they important?

An interior design 3D floor plan differs from your two-dimensional or “flat” drawing, which only accounts for length and width, by adding a third dimension: height. Including length, width and height (three dimensions) in your drawing renders a more realistic depiction of your floor plan in terms of space and layout. 

When you make a 3D floor plan, you’re not only able to better visualize your design as you create it, you can also provide a far more “real life” view of your design for your client than a 2D plan can offer. Knowing how to create 3D floor plans can greatly benefit your bottom line, helping you to more accurately convey and sell your design ideas while wowing your clients with a clear, impressive visual. 

How do interior designers use 3D floor plans?

Whether you’re needing to make a 3D design of a house or just one room, 3D floor plans are used in the interior design field as a communications and sales tool to express your design ideas to your client. Typically, an interior designer would make a 3D floor plan during the schematic phase of the project schedule, after the initial client consultation and when they’re ready to start planning the space and design. Putting finishing touches on a 3D floor plan can also take place during the proposal completion phase before presenting the final design to the client.

Elements of a 3D floor plan

Before we can explain how to make a 3D design of a room or house, we need to list the essential elements of a 3D floor plan. These can include:

  • Walls/partitions
  • Windows
  • Doors

Anything in a mood board, including:

  • Furniture
  • Lighting
  • Rugs/carpeting
  • Flooring
  • Fixtures/hardware
  • Accessories
  • Appliances

Once you’ve identified and nailed down the details of these essential elements, you’ll now be able to move forward with creating a 3D floor plan for your design.

Step-by-step: how to create a 3D floor plan for interior design

Below are the basic steps for how to make 3D floor plans and prepare them to send your clients.

1. Choose your 3D floor planning medium

Before you start drawing and measuring your floor plan, you want to make sure you’ve identified the right 3D floor plan software, like the Houzz Pro 3D Floor Planner, or other online tool to use that best suits your needs. We’ll cover this more in depth in the next section, but it’s an essential first step to note.

2. Draw it in 2D

Before you turn your floor plan into a 3D model, most every plan starts with a 2D drawing.  Depending on the software you choose to work with, you can either start with a manual 2D drawing done by hand, which you can then upload, or you can create your 2D drawing within the software program itself. Still, you’ll need to take care of any physical measuring beforehand to make sure you have the exact dimensions of your space. You’ll also want to add essential room elements such as walls, windows and doors in this stage so that your drawing reflects the space as accurately as possible. Once you do, you’re ready to convert your 2D drawing to 3D with the help of your software. 

3. Add furnishings

Now that your floor plan has been rendered in 3D, you can start adding furnishings to bring your design to life. Decorate and furnish your 3D floor plan just as you would the space in real life. Whether you prefer to begin with lighting or flooring, furniture or wall paint is totally up to you and your process. Remember: the more details, the better with your 3D floor plan, so don’t hold back on making your design as true-to-life as possible. 

4. Cross-reference your mood board

While you're adding furnishings and finishing touches in your 3D design, make sure to refer back to your mood board to assure you’re fulfilling the vision you intended for your space. If your mood board has details you feel can’t quite be captured in the 3D space, you can also cross-reference your mood board when presenting to your clients to give the fullest picture of your design. 

5. Share with clients

Whether sharing via a link, PDF or giving your client a virtual “walkthrough” of your design, you’ll want to make sure you have the sharing and/or presenting capability you need to send or show your 3D floor plan to your client. Versatility is key, as well as working with a reliable, easy-to-use program.

How to choose an interior design floor plan software program

When you make a 3D floor plan, one of the most important decisions is choosing the right software program to work with. While there are many tools available for interior designers to leverage for creating 3D floor plans, here are some important features to look for:

  • Ease of use
  • Cloud-based/online access
  • Ability to show a plan from different angles/perspectives
  • Ability to zoom in/out
  • How quickly you can create realistic floor plans
  • How many elements you can customize/change
  • How technical they are (i.e. can anyone learn them or do they require knowledge of coding/CADs, etc.)
  • Shareability (i.e. can you download as a PDF or image, can you share a link online, or present etc.)

Houzz Pro software’s 3D floor plan feature offers all of these options and more. Immersive, easy-to-use with the ability to add stunning detail and present to your clients in multiple ways makes Houzz Pro the best 3D floor plan solution for interior designers.
