This project should be done at the beginning of the new school year.
The duration of this project is completely dependent on how large of a wall you need.
KEEP IN MIND, you will PROBABLY need to drill at least one hole into your wall. Do what you have to, to avoid making the holes too noticeable. In other words... PREDICT damage that may be seen at the end of the year, hint hint. My wooden frame uses about THREE wall holes.
Why: Your roommate smells. Your roommate is noisy. You have a girlfriend. You don't have a girlfriend. Your 21 and think it's unreasonable that your University does not provide adequate housing... you would understand if you knew what we paid per month.
Everything seen in this guide can be found at lowes/home depot... I'm sure you could also supplement some of the items used for hardware found at local stores.
The wall is also really sturdy, but I think I used the bare minimum in order to accomplish this.
Without tools: $120,
With tools: Roughly $50
This project will reduce noise by about 70% and eliminate all light... mostly.
** Also, you should probably get your roommates permission.
*** The entire project took about 5 hours to complete.
**** There was no glue or joint compound used in this project, it is fairly clean and straight forward.
***** If you are concerned that your room may spontaneously combust, this project will probably facilitate the burning process.
