What should we build in our room?

My roommates and I have been doing various projects in our room in order to make our room the ultimate party room. Thus far we have built a wheel of fortune style wheel of drinking games as well as having converting our large closet into a full out pillow room and built a beirut table. We are looking for our next project and we want it to be amazing. What is something we could put in our room that would make our room amazing?
