Whether tiny homes or pod apartments, the dimensions seem to be squeezed to the point where it would be an uncomfortable squeeze for most people yet it's probably well within the range of diminishing returns of actually saving money.

The details will vary of course but so many of the discussions seem to be around whether you "can" live this way, not whether you want to, especially long-term.

I say this as someone who lives in a fairly modest-sized house but enjoys not feeling I have to squeeze every square foot out of my space.
