Put Images in 3 boxes on homepage

In the child theme pictures, you will see that they all have a slider to the left and three boxes to the right with images in the boxes.

The new page builder only allows me to have regular boxes with a title and a description. I would like it to be how it was before where you have main image/slider to the left and three boxes to the right where you can place images.

How does one do this? Thank you in advance!
