Hello all! I've enjoyed home theater for almost 20 years, starting with a Proscan 35" direct view CRT that weighed 340 pounds. During this time I have upgraded and changed things more times than I care to admit.
My theaters progressed from the living room to unused bedrooms after our kids left home. However, I never was able to figure out a way to create a dedicated theater space. About 3 years ago, my wife and I were standing on our 2nd story "catwalk", looking out over our 2 story living room when she says "too bad they wasted all of this space by having a 2 story living room instead of adding more square footage upstairs".
That got me thinking and doing some research on the structural design of our house. I'm a Mechanical Engineer, so I ran my own calculations and concluded that, in fact, a 2nd floor addition was possible. To be sure, I verified my numbers with a local Structural Engineer.
It took a little while to convince my wife that not only was this project doable, but she and I were capable of doing it ourselves. In fact, we ended up doing everything ourselves, except hanging the sheetrock on the newly created downstairs ceiling. At the end of the day, we added 300 square feet of space to the second floor while creating a new home theater.
Since the theater is complete, I've tried to structure this thread to show the progression of the work from start to finish. Hopefully, someone will find it useful. Enjoy!
