That's what i thought :LOL:

Assuming your internal floor level is the same as the DPC, then you'll need to work down with your measurements, so 175mm screed and insulation plus 150mm beams, means the beams need to sit at least 325mm below DPC. In your case the height isn't going to fall inline with the brick courses so...

I have no idea, but looking good! (y)

I'm not an expert, but as no-one else has responded i'll offer my opinion. As you are building on the boundary/wall line of a public footpath I believe you'd need planning permission whatever the size of the extension. I don't know what rules there are regarding a builder working on the...

Why is this? Is it because the wall isn't tied in to the inner leaf properly or that you're removing a return on the wall, or just that you're cutting the wall in the first place?

Thanks for all your help, mind is at ease (y).

You can see where someone might be confused though when the building regs say one thing but it's different onsite. I used 100x65 lintels across drain runs in the foundations although they were only 215mm wide holes. The building regs say 100 x 140 for doorways 900mm (actually says 150 but i...

In all honesty, it's been more stressful than i thought it was going to be, sometimes a set of drawings cannot answer a real life scenario. There are some really helpful people on here.

Oh man, another fair comment, i'm feeling very scrutinised here! :eek: To be fair, it doesn't say how big they should be. :)

That would speed up the block work a bit (i'm not the fastest!), however that would only give me 100mm bearing for the lintel rather than up to 200mm bearing with the nibs (told to use 1200 x 140 x 100 concrete lintels for internal doors or door width + 150mm either side). Do you think it'd be...

Thanks, that building regs drawing makes the window look like it's right up to the wall, but it's not that close, it'll be a 900mm window and they'll be about 250mm to that internal reveal. (550mm from external corner/900mm window/250mm to that internal cavity/nibs) EDIT: that 550mm measured...

Yes, fair comment, it wasn't intentional, do you think that will make a difference? You know, i've just had a wobble the last few days, but yes you're right i should've followed the plans (as i have done so far). Reading a couple of articles got me worried things weren't correct. The guy who...

Thank you. Just copied this from the building reg plan, it does show on there the way i've built it with the cavity.

I've just had a thought about this cavity wall and I'm actually starting to worry now! :eek: Where the two storey and first storey extensions meet and share the cavity wall at ground floor level, both walls are built in celcon lightweight blocks, but where it converts at first floor to two...

Hi Thanks for the reply. Is the 550mm just for external windows and doors near the corner then? The original design was to have a two storey extension with a part single storey, so this doorway is from the ground floor of the two storey section into the first storey section. The cavity wall...

I read this earlier, it's quite sad really that a functioning economy can't provide adequate living for the elderly but can for prisoners. Surely the government should offer these pensioners the monthly money it would cost to "keep them" in prison.

Hi I am slowly constructing my extension and everything has been going okay until I stumbled upon an article regarding openings near a wall return. It appears you need a 550mm internal return at an external corner although i'm not sure about my instance. It is an internal wall and I have an...

I had one of those screens on a P shaped bath... what a PITA, kept leaking exactly where you said! My bath was level, but the corner didn't appear to drain toward the bath so pooling was inevitable and because the screen is supposed to hinge it's difficult to seal where the hinge was. We'll be...

If you did it, who'd know! :whistle: Personally, I wouldn't bother involving building regs considering it's not going to be a habitable room.

Not sure if it would work, but try and dry the fluff (if it's all wet) with a hairdryer and then try and hoover it up with the hose attachment?
