    yes, it's based on the combined exposed internal surface area of walls, ceiling and floor.
  2. @MatthewPike the solution to this same problem that I’ve used a lot on fast-track commercial projects is using a liquid surface applied damp proof membrane: https://ardex.co.uk/products/damp-proof-membranes/ it slows the moisture movement from the slab down to a level where it no longer causes a problem to the final floor finish. ....but it’s not a cheap solution.
  3. Here's a cut& paste of the relevant clause from BS 6229:2018:
  4. Yes, we used money in an offset mortgage savings account to fund our complete new build holiday home. Total build cost was £96k for a 2 bed detached bungalow (already owned the site). edit: I’m self employed and had the offset mortgage on our main house for a long time before deciding to do the self-build. It was ideal as I didn’t need to ask anyone for a loan and full flexible access to the money in the offset account meant it was all very easy.
  5. You need to have a good read of Part B of the Building Regulations, particularly Section 11 (page 83 onwards). It's quite a complex set of regs so not easy to simply summarise here but briefly the closer your building is to the property boundary then more of its wall will need to be fire resisting construction. https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/832631/Approved_Document_B__fire_safety__volume_1_-_2019_edition.pdf
  6. Chrome is a much better browser than Safari. About 6 months ago I switched to Chrome on my iPhone after experiencing major problems with Safari and no problems since then.
  7. @dnb if you're painting you may as well save a shed load of money and use pressure treated timber
  8. Have you tried Worktop-Express? (Edit - I used them 3 years ago and they were very good. Also a lot cheaper than Ikea)
  9. @Tony K heavy clay soil can be a nightmare in Winter for obvious reasons
  10. That’s 2nd fix so a valid claim.
  11. @SKB I’ve seen that problem a few times over the years on my commercial projects and each time it happened it turned out to be an issue with a traditional sand cement screed which had been laid with insufficient water in the mix. When there’s insufficient water the chemical reaction can’t take place right through the thickness of the full screed depth so the surface typically forms a hard skin that is 10 - 20mm thick but the main body of the screed doesn’t cure and remains as a dry mix. The surface skin obviously can’t bond to the rest of the screed and it isn’t thick enough to take normal loads so eventually it starts to crack up just like your photo.
  12. Then it’s a ‘no-brainer’ to go with the 2G version. Winter is coming
