Hmm. That's what I didn't want to hear.
How would I go about opening it up? Remove a brick or 2 at the end of the beam so I can see the section?
I wonder if I could actually work out what's going on by drilling a hole from either side.
This is where I saw it listed as a standard size:

Is that wrong?
I've just had another look at it - and I'm not sure if it is 2 L's back to back - it might be a T. In that case it would be a total of 280mm wide. Does...
Hi,
I wonder if anyone can help. I had a single storey rear extension built last year, but the builder vanished before we'd got everything signed off by buildings control. The final thing i need to get the extension signed off is confirmation that the lintel used over the rear bi-fold doors is...
Ha, My builder's been on holiday for over a year then!
I've got someone to check the lintel used - it was easy enough. It's a 225 x 300 36kg universal beam. I've been told that this is more than enough to support the weigh involved and will have no problems with the buildings regs. Does anyone...

I don't think it was done under a buildings notice. Plans were submitted beforehand along with structural calcs for the opening made in the previous external wall. Site visits were carried out throughout the building process and only after it was complete did the control officer ask for calcs...
Yes, under buildings control. Extension is complete, and I can no longer reach the builder that did the work (has vanished off the face of the earth apparently). Weeks after "completion" the buildings control has only now asked for structural calcs for the beam over the doors, despite site...
Hi All,
We've recently had a single story rear extension built on our house. It has a pitched roof, with bi-folding doors in the wall under the gable end. The doors are 3600mm wide, the whole extension is 5500 wide.
There are no joists resting on the wall above the doors - do we need to...
