I wonder if this is considered a good job or not? I'm just going to trust Celebration Homes on this.
I think this is what they call "manholes" Correct me if I'm wrong. Definition from Wikipedia is " A manhole is the top opening to an underground utility vault used to house an access point for making connections or performing maintenance on underground and buried public utility and other services including sewers, telephone, electricity, storm drains and gas"
2 man holes required for this tiny house.
Next stage will be brick delivery and bricklayer commencement.
