This project involved turning one huge bedroom with no privacy between the two beds into a 2-room assemblage which gives the homeowner a private bedroom and separate flex room (in this case it contains a full-sized bed). A clerestory frosted glass opening was added to allow natural light to enter the inner-most room. The glass is 1/2" thick and the 2-1/2" light-metal-framed walls were packed with acoustical insulation for sound attenuation between the rooms.
