Interior Sketchup Attic Bedroom Speed Model | Trimble Sketchup and Lumion Render

This speed video will show you how we took a 2D reference image and turned it into a 3D interior Sketchup model! It’s a fun process, and with practice, you’ll be able to take any image and turn it into a realistic rendering!

We began by selecting an image that would be easy to convert into a 3D model. You can find free images on Pinterest, Unsplash, Pexels, our my personal favorite Art Station. Just be sure to credit your source! Look for an image with a strong 2-point perspective to add dimension and clear lines to help you more easily construct the room.

Our image is a cozy bedroom scene with lots of warm, natural light. The walls and other architectural features are very defined which will make locating intersecting planes and creating the interior Sketchup model much easier.

After selecting an image, we uploaded it into Sketchup as a matchphoto and use our scale figure to find a scale that’s appropriate. Photomatch will help you locate the horizon line and get a feel for how big the space will be in three dimensions. We then established the major planes by creating the walls, floor, and sloped ceiling. We don’t know what the entire room looks like, but we can assume the other half is going to be a mirror image- of course you can get as creative as you want or need! Since we’re only planning on rendering this one view, we just want to make sure we create enough of the environment to generate a render with the correct lighting conditions. Don’t overdo it here! Only model what you’ll see in your render or what is going to affect the lighting. Your time is precious, so don’t waste it on things you won’t see.

Once the outline of the room was created, we changed the color of the planes to represent what was in the picture and give the model a more natural feel.

Then, we started adding the defining architectural details such as the ceiling beams, window frame, and skylight to make the room come alive. Once everything was added, we cleaned up the interior and exterior walls to make it a smooth surface.

Rendering the Interior Sketchup Model

When we were happy with the interior Sketchup model, we imported it into Lumion to start rendering. There are a ton of great features in Lumion that will allow us to create a realistic view. We put it in a lakeside setting to complement the atmosphere of the image. Using the original image for reference, we added materials to all of the surfaces. Then, we imported models from Lumion’s library and the 3D Warehouse to complete the interior. More customized models, like the unmade bed and cowhide rug, were imported from the 3D Warehouse into our interior Sketchup model before we could render them in Lumion.

Once the interior was finished, we added some foliage in the background to make the room feel more secluded and to dress up the exterior. When everything was placed, we selected a view that matched the original image. We played around with the sunlight settings, tweaked a few materials, and that’s it!

Transforming a picture into your own 3D model can be a fun process and a great way to practice your modeling and rendering skills. If you really want to practice your skills, you could even take one image and use it as a jumping off point to create an entire home around!

    In the NCARB ARE 5.0 handbook they reference Fundamentals of Building Construction: Materials and Methods in both of their example questions for cost estimating. Unfortunately there isn’t a specific chapter on cost estimating, it’s woven throughout the content.

    What is the best reference for cost estimating for PDD.

    Deciduous trees should only be used for shade (especially in temperate climates). Deciduous trees lose their leaves in the fall and will have little protection against wind in the winter when it is most needed. Likewise, the leafless trees allow solar heat gain in the winter when it is desired, and shade in the summer.

    Coniferous trees are only to be used to block wind and views. Since they don’t lose their needles, they work great for these two items year-round.

    Hello. My name is Shahid. This comment is for anyone who would like to reply. On the Siteplanning test. To block the wind, can you use a Deciduous tree or must you use a Coniferous tree?

    Hi Tony,

    I need to take 5.0 PPD & PDD. Do you plan on posting notes such as “Caroline’s Notes” that you had posted for the various 4.0 exams for either of those sections? I found those notes to be some of the best resources in studying for the 4.0 sections. If so any idea when? Thanks

  24. Stephen October 17, 2016 at 9:30 pm #

    Hi Tony,
    Any updates on the SS exam ? If there’s an expected release date ? Thanks

  25. DesignerHacks October 4, 2016 at 12:11 pm #


    We are releasing practice exams for the SS exam later this fall.


  26. Paige October 4, 2016 at 11:34 am #

    Will you have SS questions on here at some point?

    Great post, very helpful with the lists of suggested materials, I just passed CDs in July and am taking PPP in November so I definitely needed the list.
