# Are lally columns direct indicators of load bearing walls?

I have a hip-style roof where the first floor is set up as such (- & | are walls; = & || are doors; + are lally columns; gaps are empty spaces or openings):

It's a poor representation, I know

...and the basement:

I'm trying to understand what the purpose of some of these lally columns are. Some support walls on one side of the house but are not required on the other side, making it asymmetrical.

Which tells me these columns (+) are only supporting the load directly above them but not the roof above. If I tear these walls down, would those columns be necessary? Or would the house be safe if I removed the columns? I'm not referring to the columns directly going through the middle of the house.

EDIT: As an example, I have one wall I'm considering removing. However, there are two lally columns directly beneath that wall. There is no beam running across the opening of this wall, so I'm assuming it's not load bearing. Also, there are no other loads above the wall except for the roof. Could the one lally column (right-side) simply support the wall above it?

• Your floors are supported by the beams and joists that are connected to some of the columns if not all. Be careful what you intend to do.

• Hire an architect and an engineer to ask these questions. Without that, all you can do with complete safety is remove anything you want from your ascii art :) Feb 7, 2022 at 22:56
• Lally columns are usually not added/used for the fun of it. If they are there, then there should be a very good reason for their placement, and removing anything needs expert advice. They are not there to be a coat rack. Feb 8, 2022 at 1:16
• Without knowing the dimensions or materials we can't be sure, but it's possible the columns are supporting a beam and the floor joists go from that beam to the "north" and "south" walls in your diagram. If that's the case, removing the columns would mean replacing the beam with steel and strengthening its supports on the "east" and "west" walls. That is exactly how my house is built. Other things are of course possible too. Feb 8, 2022 at 13:51
• Look in the attic, is there a beam going north/south directly above the right end of the wall with the painting and above the right hand column? If you have a second floor you'll need to consult drawings ... do you have them? (Using directions per your drawings) Feb 8, 2022 at 15:45
