The closest I can think of when it comes to real-world devices that have a large reduction ratio, would be something like the mechanical tachometer/hour counter combinations seen on old tractors and similar -- where the dial indicates something like "hours at 1500 RPM". That makes for a reduction rate of 900000 from the engine shaft to the rightmost wheel of the counting device if that were to rotate once per 10 hours.
But in these, the reduction would be done via several stages of worm-drives, and the reduced speed is important, not the increased torque. And they are thoroughly obsolete -- anything made since the 1980s would use electronic devices to do this.
For torque multiplication, this would require some seriously strong materials in the later stages. Even then, the total power would be limited by the maximum speed of the first stages as well as the maximum torque of the latter stages. Yes, with sufficiently strong materials it could move a house though it would have to do this over a period of several months. Hard to see how this could be practical outside of mechanical instrumentation applications.
