“From the four walls that currently surround you”, eh? four walls? Traditionally, walls of a house in humid climate area are not fixed. A line separates a room from another could be a wall and also a kind of sliding door. In other words, a large room could be separated into small rooms flexibly by doors or something like partitions.
Interestingly, I found that FOV was similar to the first one but why? One of the reason is, perhaps, in both cases, better usage of available space are always required.
