House with a basement from 1949. How is the structure made if the description says '12 cm concrete structure with 2" x 4" floor joists'?
Are the floor joists embedded in the concrete, or do they lie on top?
A technical question as well, how was it done when the house was built, was the concrete poured on site? Patterns in the basement ceiling look like they could come from a mold.
Thanks!
