Lintel size and position.

[camerart]

Hi,
I'm installing windows into a wall, and want to know the size and position of a Lintel, for a 1.2Mtr wide window.

Looking at the photo showing a blue lintel. I understand that the window has to be 600mm from the corner, but can the lintel encroach into the 600mm, as shown?

Your opening does not need to be 600 from a corner unless you have calculations or special reasons requiring it to be.
That dimension does not include the lintel bearing.

Hi W,
I've just found my previous question, where this was answered (I couldn't find it before)

RSJs etc for fitting windows

Hi, I would like to add windows where the white lines are on the image. Does this seem ok? RSJs or lintels will be necessary. Are calculations needed for planning permission? Cheers, Camerart

This has been confirmed by the Building control inspector.
Can you clarify, can the lintel encroach into the 665mm from the corner?

The approved document guidance relates to the opening, not the bearing.

And it is guidance, not a requirement.
If you require the opening to be nearer a corner and the inspector wants confirmation, then a structural engineer can do the necessary calculations for that type of lean-to and it will be OK.

Hi W,
As it's an old toilet, with single 9inch wall I'll go along with the 665mm from the corner, and keep it simple.
So from what you say, it appears that the bearing can go to where I show it on the drawing
