Saturday Omphaloskepsis: I like small houses, but this is a bit extreme

I am enamored with small houses, and I like the idea of living in a small house: you have to pare down the things that you have, since (unless you buy a storage facility) you just don't have enough space to put things in a small house. In addition, much like in a boat, the need to conserve space means that you have to multi-purpose many pieces of furniture, doing things like making a staircase act as the framing for a storage area or having multifunctional furniture. I find these projects interesting, because I find the solutions need to be innovative and, therefore, the construction and design challenges interest me.

Of course, there are cases where small might be a little TOO small. Thus is (potentially, at least for me) the case with the Keret House in Warsaw, billed as the "world's narrowest house" (probably not, but who's really counting).

Via Inhabitat:

Could you live in house no wider than a door frame? Etgar Keret can. The Israeli writer is now the proud owner of the world’s narrowest building, a home so tiny that you might not even notice it if you’re not looking hard. The house, which is less than five feet across at its widest part (three feet at its narrowest) was designed by Polish architect Jakub Szczesny and is located in Warsaw, the country’s capital.

Kinda narrow and a little too vertical for my tastes. After all, I am a kind of broad-in-the-shoulders guy, and so a house that narrows to about 3 feet will be a little... close. Furthermore, in a previous story on Keret House, Inhabitat reported the following about the amenities:

Electricity will be provided by a neighboring host building, and a water and sewage system in the small space will be free-standing, much like systems used on boats. The first floor of the living space is a work space and a lounge. The second level, reachable by ladder, fits a sleeping loft with a skylight. The top space can be used for storage.

I wonder how much sunlight this house actually gets, and how would one go about cleaning that skylight?

It's all kind of cool and fun and interesting, but - for me at least - it takes things just a little bit further than my interest.
