Here are pics of my son's room. We converted our basement into a bedroom for Henry (don't worry, we kept the guest bed so that we can still host guests, if they dare.)
The basement before:
The only thing missing is a project we have yet to complete. Behind the train table, we are going to use chalkboard paint to create a chalkboard on the wall. After pricing chalkboards, I found that making our own chalkboard using paint was WAY less expensive considering the size of chalkboard that I want. I'll post pics as soon as we complete the project.
You know what I love most about this room? My son LOVES it. Come over to our house and the first thing he'll want to do is show you his room. He can go hours - literally hours - simply playing down there. Henry is quite the introvert, so having a space where he can retreat has been so wonderful. I'm so thankful that he has a space of his own. I really hesitated moving him to the basement, but it has been such a blessing.
