This is my son's 11th Birthday present. He didn't ask for anything like this, but he did play on a pad for almost a year before he even mentioned he'd like drums, so we got him a drum set for his birthday. I build the combination Lego table and framed drum area to try and make the most of the area, and to give me something to hang/rest the sound absorbing panels on.
The panels are just wood frames packed with rock wool and wrapped in felt. I may have gone overboard with them, but the room sounds so much better with them up. Just a side snare was impossibly reverberant and painful without the panels. The blue hinged panels behind the bass drum are actually filled with two of the 3" thickness sound absorbent rock wool sheets that were packed down to fit in a 4" thick frame. They work very well as a bass absorber even though it's not in a a corner.
