This step by step tutorial of how to build a false bottom secret compartment drawer is a simple do it yourself project that can hide valuables from plain sight contained within a drawer. It is not a high tech or super safe option but it can hide items if people are not looking too hard or rummaging quickly.
If you need something more secure, you may need to look into a small safe.
It loses its secrecy only if it’s easy to spot, so a good secret compartment is modestly sized and well-camouflaged.
