Turning garage into bird-room HELP

[Blue]

We turned our garage into our living room... even before the birds were in the picture. My husband works nights/ sleeps days, so when our daughter was born we did it so she could make noise and he could still sleep. Now our birds are in here too, for the same reason lol. He's put in a window, door and steel security door, built in ac, a skylight and insulation. The big door is covered with insulation board inside and out and the cracks are spray insulated on the outside.
