Has anyone considered a high security safe for their valuables? Because high security safes are so heavy and could be damaging to a normal household floor over time... that could present a challenge. Perhaps install the heavy safe inside your garage bolted to the concrete floor? Would have to solve for moisture and temperature changes in a non-climate controlled garage of course. Also if inside your garage, perhaps placement against a back wall (or creatively hidden) so as to not be easily visible to passersby and neighbors.
