Is the rubble part of the structural foundation

Hi there.

I'm currently wanting to up do my cellar. It's has brick walls all around the cellar. As you go down the steps to the left. There's a wall that has been broken down. Which then as uncovered a mound of rubble. That's kinda like soil material. The mound is probable just over a meter high. But does go higher towards the back wall. In the middle of this back wall there is a chimney breast. My question is can I remove the rubble. To create more room. The rubble does easily pull apart.

"That’s is just rubble , the building is sitting on a foundation that has been dogged up to a metre down. Then concrete poured , then brick work is built the house. But do get a second option before you do anything from an experienced builder."

"Hi,
I assume this is an old building, in older times they used to use rubble infill below ground floors etc…
This would not be structural or as a foundation type of any kind, the only thing it might have been used as a support for the wall to resist earth pressure. I have seen these types in older cellars. (Some photos might help to make sure)
The only thing I am afraid if you remove it and it has been used as a kind of support (possible) your walls might start to lean inwards over time (not a high chance but possible as said without checking or photos cannot he sure)
But overall it would be an issue just make sure you insulate for moisture travelling upwards etc.."
