Lintel Check

[thomp1983]

Hi,

Starting to get ready to knock through into our new extension and just wanted to check the lintels will be sufficient,

As you can see in the first picture there is a large concrete lintel spanning the window, there's 3 of these across the entire rear of the original house and they've been there since 1971.

I plan to remove the window and brickwork below it shown in the second photo, I'm fairly sure the lintel is more than sufficient as that's all that's ever been there, the window doesn't support anything and the brickwork below is only supporting the window but I just wanted to check before I go too far

Thanks
Chris

Whilst it's not fully clear, it looks like the lintels span onto the intermediate masonry pier (lintel span around 1.8m). Removing the pier will significantly increase the span to nearly 4m and hence overstress it. Steel beam needed

Piers staying in place, literally just the window in second picture and the brickwork below it is coming out, everything to the sides is remaining in place.

Arhh, that makes sense, sorry thought the intermediate pier was coming out. In which case, the load to the lintel doesn't change so you can remove the window and the brickwork below it

That's what I thought just thought I'd check and make sure I hadn't overlooked anything
