What lurks behind hidden doors? In this video, Matt Risinger, master builder demonstrates how a killer art studio. At a remodel project, is an amazing art studio. All of the walls are lined behind this hidden door lies a killer art studio. All of the walls are lined with Homasote, a recycled paper product that comes in 4X8' sheets and is approximately a half inch thick. It can be used as a structural component of interior wall systems to provide superior sound control. Put a coat of paint over them and it's a pin board where every one of the walls can hold artwork. It has a ragged edge and aluminum trim, a great inexpensive and nice detail.Track lighting in a U-shape is all the way around the room. There's also a beautiful closet that is inexpensive, but functional, made from prefinished plywood, edges exposed, and a simple coat of polyurethane. A stainless-steel slop sink for cleanup completes the picture.
