"When revamping my basement there were a couple of areas that would have made perfect places for secretive compartments. Under the back porch of my house is an open area about the size of a small bathroom. I poured cement for the floor, reinforced the walls,waterproofed the ceiling and I have a storage area that most people do not even know is there. You can build yourself a safe in the
. wall and put a picture up over it. But this is a very obvious secret compartment. You can take a cedar chest and put a secret compartment in the lid of it. Make a lid inside the lid and cover it with material. , put a latch on it like what is on the back of a picture frame. Most will not know that this is a secret compartment. Some people put their secret compartment inside a wall between the studs. This would not be real accessible though, unless this is the kind of secret compartment that you want."
