  1. Yeah I think I'm going to boost it up to at least 100 if not 150 like you suggest. I found this picture where the bearing looks about 50mm, but it's granite so being a harder stone, I guess this makes it possible
  2. Yeah I appreciate it will make it a whole lot cheaper but it's not a house I'm intending to flip, so want to get it right. But equally think what I've drawn may cause issues. I'm wondering how they managed to achieve this - Super deep reveals with no exposed lintels. My guess is that they cast the stones into some kind of concrete lintel.
  3. I did wonder this. I've seen it don't before where the edge of stone head aligns with the opening reveal (I.e so no bearing at all). No idea how you'd do this.
  4. Because then you'll see the underside of the steel when you look up below the window
  5. I need to order my stone cills and lintels asap but getting cold feet on how I planned to do it. Interested to know what others think - Whether I'm being a little mad or if it will be okay? My intention was to have a natural limestone lintel self supporting. I only wanted it to bear onto the stone walls either side by 50mm (for visual reasons) but now questioning if that's enough. I'll then stick a Catnik CN71A (or similar) above it with a 10mm gap for deflection (so the steel doesn't crack the stone if it deflects). This steel will have your typical 150 bearing each side. I want to keep this above the limestone lintel so when you look up at the window, you don't see any steelwork.

  7. Hi All, Reposting this as I originally put it under 'General Construction Issues' and haven't received any comments. I'm just looking for a sanity check on my foundation detail (to hopefully provide some peace of mind before I keep building up). I'm constructing a highly insulated new build (200mm PIR above DPC, full fill XPS below DPC). My foundation detail is based on a Greenbuilding Store case study: https://greenbuildingstore.co.uk/golcar-passivhaus-ground-floor-foundations/ I originally designed it as per below, where the Surecav meets the DPC: Full fill XPS below cavity tray. Then the offcut pieces of the XPS are used above the tray below the first wall tie. Kingspan PIR is then used above the first wall tie up to eaves. The problem occurred when attempting to add the XPS back in above the DPC (to fill what would otherwise be a triangle cut out). The thickness of the DPC caused the XPS to get kicked out compared to the PIR above. This meant that there would have been a step in the SureCav. To get over this, I introduced a second cavity tray that lapped up the face of the bottom board of PIR and effectively did a solid fill cavity below where the stonework just got built up to the back of the XPS. Does anyone foresee any issues? My worry in hindsight (after building up past this to about 4ft, is that the cavity tray I inserted only laps up the face of the insulation. Any water ingress behind the insulation has nowhere to go. Am I over thinking this and it will be fine, or do people think I may have issues in the future?
  8. Hi All, Just looking for a sanity check on my foundation detail. I have a highly insulated build (200mm PIR above DPC, full fill XPS below DPC). Based on a Greenbuilding Store case study: https://greenbuildingstore.co.uk/golcar-passivhaus-ground-floor-foundations/ Cutting the insulation to the falls of the DPC cavity tray was an absolute headache. We ended up setting up a jigg and then using the offcuts to bring XPS up to create a flat ledge below the first wall tie. We then started the PIR above this. When installing the XPS above the cavity tray, it kicked out compared to the PIR above. This meant that there would have been a step in the SureCav. To get over this, I introduced a second cavity tray that lapped up the face of the bottom board of PIR. Will this work? Does anyone foresee any issues? I've already constructed up to about 4ft along one wall so hoping this works but equally stressed about continuing as it will only get more expensive to rectify if there is a problem. Kind Regards, George
  9. I had the same issue recently and was quoted 13.5k to move it. I asked about wayleaves and she said they'd move the pole for nothing but wouldn't allow me to connect into it for the new property. Managed to solve it in the end for much less (just putting in a taller pole which isn't ideal but gets' me out of trouble). I would suggest getting clued up on wayleaves before having NatGrid out.
  10. £18 an opening sounds crazily cheap?! Do you mean per length? When I priced it up in Timloc, it was about £30 ever 2.4 metres. Worked out about 1k for the whole job and I feel I don't have that many openings. That's also not including the cavity closer at the eaves, but I was thinking of just closing that off with cementitious board?
  11. Building Control were happy with this? I thought it had to meet certain fire requirements, which the cavity closers you buy have been tested against?
  12. Also how have you guys got around the cavity closer issue? Where I have wide cavities, the only closers I can find are about 30 quid each. Over £1k for my whole job 🤦‍♂️
  13. Just done the same. A few people whispering in my ear though that they think damp will track across, even with the o rings. Any issues so far for those that have used them? Also are they tricky to install with PIR? Don't know if they will not sit very well and cause the insulation to kick up where they are quite thick? I may be over thinking it though 🤷‍♂️
  14. Thanks for the advice and you've mostly summarised what I have been feeling in my gut. Just ordered both books - thanks! Pretty much planning to do exactly this but potentially with different people now - Someone to stick up the blockwork and insulation (same guy that did my retaining wall. Hiring direct as opposed to through the groundsworker). & spoke to a stone mason who wants to do just the stonework. Also scaled back a lot of the stonework based on what his m2 rate. Yeah you've hit the nail on the head with this one. I wanted a drystone wall look, which is why they're reluctant to price per m2. In all honestly, I'd rather they work day rate and put a little care and attention into it as opposed to just wacking it up (not doing this as a project to flip). All I wanted from them was a very approx m2 rate so I could see if my desire for a drystone look was completely unrealistic, or whether i needed to scale the quant back (as I have now done after speaking to a different mason, who has come back with approx 180 per m2). Yeah - I'm on site most of the time (working from home but heading out every hour or so to answer any questions, provide any missing setting out info etc). In terms of materials - I'm calculating quant's for everything now - Pretty long process but getting there. I'm ordering materials myself so planning to phone around the builders merchants to try and get the best deals possible. They said they don't use labourers (not really sure why?). But all 3 of them wanted 190 a day each... £2850 a week. Going to start adding up quickly.. I attempted to keep it simple whilst also keeping the planners happy (going for a modern cottage vibe). Distance between neighbouring garage and site is 700mm, and the same applies the other side where there's a 1.2m retaining wall). Planning to make these elevations timber or render now to save on cost so access for stone laying is not longer an issue. The only stone will be the three gables and the bit where the bi-fold door is shown. The rest will be charred timber (including the bit that I originally intended to be corten, which I have discovered is mega bucks). The window with a cross through it is also going (to reduce cost). Cheers for the advice!
