Some issue with bringing this design into today:

- air quality (especially if closed off), less air volume means the air gets bad faster

- air humidity, raises faster through sweat in a cupboard setup, for the same reason the inner tent of good tents tends to be made of a fabric which allows air humidity to go out of the inner tent (I think, haven't bought a tent forever)

- fungus mainly due to the higher humidity/reduced ventilation the chance to have a fungus infection in your box (and also/especially the bottom of you mattress)

All of this where issues back then too, just so much smaller then the risk of freezing.

A risk we currently tent to not have in apartments due to better heating, insulation (even on non insulated housed due to better closing windows and better thermal isolating glass). Not being in a short little ice age also helps.

Capsule hotels are somewhat of an modern version of this. They tend to have some form of AC in every capsule to fix the air quality issue and hugely reduce the humidity and in turn fungus issue

If you are stuck in a situation where idk. heating is broken and its dam cold creating a similar setup by e.g. butting a tend on your bed can still be a grate idea.

A good ducted ERV could solve all those problems

In the end we're going to end up with something something that's the mix between a coffin and a computer case. Fan noise would be a big issue.

At the same time, for small volume, it’s much easier to condition and monitor the air to exactly how you want it.

In the current culture bedrooms are more than simply a place to sleep. In multi-member households, a bedroom is typically a person's only personal space.

“Personal space” for anyone below the rank of, say, a duke is a very recent trend

Not having dukes around, along with higher global avg prosperity, is also a very recent trend. And seemingly a pretty good one.

Yeah. Screw dukes.

Careful with talk like that, one might be about, might take offense and want to um, them it out..

I'll see myself out.

Cliché, but completely untrue. Personal space in general is a very recent trend. No one with a retinue, servants or a big family has personal space…

The newest term is "Owners Retreat"

Imagine a large American 2 story house, where the "Owners Retreat" is on the first floor, a single bedroom, bathroom, multiple cosets sometimes with a small separate kitchenette, laundry, and reading/tv/living space.

This makes a lot more sense for what I'm planning to build. We're used to calling it "Master bedroom" where I'm from, but I always imagined I'd want some sort of suite or apartment, separate from the rest of the house.

Late reply but here is an example https://www.youtube.com/watch?v=INFPFC1P-iw

There called an in-law suite here, and are generally used as a form of multi-generational housing when old parents move in with their adult child.

I know what you're talking about but that is a different space.

I can recommend sleeping in a Tesla’s trunk. Very cosy. Mobile. And air conditioned.
