We are converting a previous storage room in a garage building that is divided by a wall to create a second garage space. The garage floor is made of cast reinforced concrete.
There are two culverts under the garage building (about 1.5 in height), one of which under the storage room reveals an opening in the floor about 1x1 m. The storage room has been framed on top of the concrete with a wooden floor about 2 cm thick, chipboard, and glued vinyl flooring. The studs are spaced about 40-60 cm apart, estimated to be 8-10 cm high.
The vinyl flooring was removed due to odor, and part of the wooden floor was pulled up to access and remove a radiator and associated piping directly under the wooden floor.
One idea was to remove all the flooring and use the concrete as usual, but due to the hole, it means that the hole would need to be filled before it can be fully utilized.
So my question is, is it suitable to use the current construction to park a standard-sized car on?
