Having a small area to build our house and with my cousin’s house at the back, we had it made with firewall for safety and privacy of each other,  firewall are often use to separate two residential units. It intended to slow the spread of fire from one side to the other, it was proven helpful in many incidents like when there’s fire in our small town some of the houses and establishments were saved by the firewall.

Having it made with firewall my cousin’s house cannot be seen anymore, there’s no choice but this is what is best when the houses are near each other.
