    Hi. Hoping for some advice on whether I need a concrete lintel or steel on an external cavity wall. I’m going to be building a porch on the front of our house. It’s a traditional semi detached with an arched storm porch and front door set back. I will need this knocking out to open it up for the new porch. Speaking to a builder who has done an identical one to what I want around the corner he said he used concrete lintels which I was surprised about as I thought you would need RSJ. The opening will be 2150 mm so would need the lintels to be 2450 mm as I understand it. Can anybody tell me if this guy is right saying concrete will suffice ? Bear in mind it is right on the corner of the house as well. Many thanks in advance

    If it's of any use, the engineer has asked for concrete lintels (100x140) on a cavity wall which is flanked by an extension, thereby not visible. As I understand it, if it is not visible then you can (should?) use concrete.

    It seems like this will need building regulation approval, in which case the inspector will either accept or refuse the builder's suggestion.

    Two course deep conc' fellas will be humungously heavy.

    Use steel (proprietary) every time.

    Thanks. I guess I’ll speak to the building inspector and if he says it’s fine then I’ve nothing to worry about.
