Thanks. Yeah its all tied to the inner blockwork - the corner only has a tiny (30cm) return as then straight into a doorway (probably how it ended up with the lean as I was using to level to ensure the doorway was level and probably slightly pushed the other side out). Won't be rendering as...

I have put up a brick wall for a single storey extension I am building myself. Somehow or other I have managed to build one corner slightly out of plumb - its about 15mm leaning outwards at the top at one corner. Is this a big problem, or nothing to worry about? It's approaching 3m high - the...

Cheers. Only reason I was thinking of doing 1 brick then block then back to brick was because I am joining existing foundations at either end (where I am building an extension onto the house), so one brick would bring things up level with the existing footings, then I can run blockwork along the...

I am getting a delivery of ready-mix concrete (C20) delivered on Saturday morning for my foundations, but my supplier cancelled and the only other supplier I can find for this Saturday cant deliver as much as I need (they only have a 4m3 truck and I need 4.4m3). Given I am only 0.4m3 short, and...

Almost ready to get started on this now, just want to double check the temporary support... I am thinking of using strongboys on the outer wall skin (one every 70cm or so), then support the inner cavity skin by using scaffold planks on acrow props holding up the floor joists (as they run 90...

In case its of use for anyone else - having spoken to the structural engineers again and challenged the complexity of the diaphragm design, they have changed their minds and are now happy with spacer tubes at 400mm centres staggered 50mm above and below the centre line. Was really worth...

Yeah, just been quoted £798 for the SE design to be fabricated, vs £204 for simple beams pre-drilled for M16 bolts (and I am sure I can find some scaffold pole and cut it to size myself for spacers). Any advice on the spacers - 600mm centres OK? Single M16 bolt or two (one above other)? All in...

Thanks Tony - you echo my thoughts exactly . I have been trying to get more clarification from the SE (eg how the bolts will go in), but they only seem interested in helping if I pay their hourly rate (which seems a bit off to me given I am just trying to interpret their technical jargon). I...

Cheers Tony. In terms of the RSJ beam, the SE have spec'd that the two beams need to be secured together using PFC diaphragms welded to one web and secured to other web via 10mm thick MS endplate welded all round with 2No. M16(8.8) bolts. Is this overkill - I have seen others on here just...

Yeah I have been considering strongboys, but my understanding is that they old hold 1 skin, so if I had them outside I would still need to find a way of supporting the inner skin. I have read that I can potentially support the inner skin by just proping the ceiling (the ceiling joists run into...
