Laundry Room

My coworker was so proud when she brought in some shotty 3d designs of her proposed kitchen redesign. They were pixelated and the appliances were just little boxed stand ins. I thought I could try my hand at room design so I came up with this. It isn't done yet and I'd eventually like to design a whole house in 3D. I want to know what job the person that made her designs has and apply for it myself.
