Keeping in mind what your basement can handle, lets look at the measurement of your basement and draw out a plan. Remember, you should keep everything realistic. If you plan on having a pool table, be sure there is enough room for the walls to be placed and for people to be able to actually shoot pool! It’s incredible how many times people don’t plan for this type of thing, just to be frustrated with the lack of space they have.
Also, remember if you are placing a bar to be sure you have the size that you need. That would include seeing what it would look like by measuring everything out in person.
