Remember that pozo often means (vertical) shaft. I do translations on tunnelling for subway (metro) railway lines, and it comes up all the time.

@Robert Your description matches my own apartment, which has a light well (called a patio de luces where I live, but it's the same thing) at one side, surrounded by my property on three sides, the fourth side being the property line with the next block. Mine is square, but my neighbours in my own block have a five-sided light well at the edge of their apartment, one side of which is again a property line.

Por la derecha: Con propiedad de terceros y pozo de luz no. 2, con una linea quebrada de cinco tramos. ["Skylight" definitely does not fit here.]

I am thinking possibly a skylight but that does not fit what you are saying about the text or a glass room/enclosure connected to the house.

source text? Can we get a bit of the passage with the words included?
