Internal wall demolition, catnic, needles and stand props?

[smarriott]

Hi

Looking to knock through an internal wall. The wall is single brick and extends upstairs but does not support any roof structure.

I am looking to generate a 2m apeture and have been advised by my architect that a 2.4m catnic lintel will be sufficient to take the load.

Can I simply carve out a 2.4m slice of the wall, install my catnic and then work downwards removing the brickwork? Or should I really use a prop and needle approach?

Can I rest the lintel on the existing brickwork or should I a concrete padstone?

Cheers

If the wall extends upstairs then assuming you are putting the opening in downstairs, the wall is load bearing so you should use temporary props to support the wall above.

You should support the upper wall while you insert the lintel. What sort of Catnic lintel did your architect recommend? Do you want it inside the ceiling line or is it going to project below? Is the wall blockwork or brick? Is it running parallel with the upstairs joists or across them? If it’s across them & also supports the upstairs floor joists, it’s a lot more work & you may need an RSJ!
