  1. If your outer skin is brick or block what you have proposed doesn’t work brick or block. try 150mm of eps and 75mm screed no need for double dpc just one under the insulation married to the wall dpc is fine.
  2. can see why they didnt batten out the underside of those joists to support it as the insulation wouldnt fit.
  3. there are only two ways to insulate a roof, warm and cold. cold roof is easiest as it needs no vapour barrier as moisture rising through it and dew forming inside it is vented as its open to outside air. warm roof on the other hand has to be sealed so moisture rising up from the house cannot get into it as once it does it cannot get out and you will have mould/rot/mushrooms growing. The main issue with a warm roof is having enough build height as they are a min of 150mm deep usually. obviously in an attic roof you wont have anything like this space available between the trusses so you have to go with a cold roof and copious amounts of ventilation above the insulation via the eaves and ridge.
  4. id make sure to have a minimum of two outlets if its an enclosed parapet. Is it a warm or cold roof ?
  5. pipe a gas supply to it also, they are much better (cheaper) to run than the electric ones.
  6. amazing looking shed, now to brick it up!
  7. bit like putting the 50p's into the electric meter in the 70's.
  8. If the flat roofs are open to the elements underneath why bother with VCL and insulating ? Wouldn't bother with vents either as wood breathes. If on the other hand the space under them is going to be heated then you need to decide on a cold or warm roof design. Warm being far superior.
  9. mains gas an option ?
  10. they 'work' for the elected councillors. Attend the next meeting of the planning committee in person. Our local council is equally useless, it takes a certain type to work for the public sector ......
  11. get your local counciller on the case. even if they issue a notice you can appeal it.
  12. only one thing is guaranteed with hidden gutters. They will block and they will leak.
  13. do you think they updated the maps for next time ?
  14. i dont see the problem here, dpc is working as intended ?
  15. job for your local councillor.
  16. you buy the map from the utility company, they are indicative only.. You CAT scan and keep a record off it. Then if you do hit and damage you can argue your case against costs. Your lucky with electric if it was BT you could be into tens of thousands. http://www.digdat.co.uk/ is a good start.
  17. Can you raise the front of the drive so the water bypasses you from the T junction ? How is the T junction drained, are there ditches or piped ?
  18. grey water pumped chamber. As we all know soakaways are a waste of time in clay ground so it has to go somewhere else, normally the sewer although the sewer companies dont like it.
  19. try www.online-bedrooms.co.uk they can produce a CAD design of your requirements for no charge. Just under half the sharps prices i found and its made to measure.
  20. imagine the surprise. ...
  21. this is a really good example of why many warm roofs fail. A combination of lack of properly sealed vapour barrier and the insulation (or lack off) bringing the dew point into the building.
  22. just read the regs 5.16
  23. bit silly having to pull out a WC to rod it isn't it. Always try and build to the best standard not the worst.
  24. only relevant to multi property storied buildings. Not single occupancy houses.
  25. they are correct you cannot use a Y for 2 WC's as they cant be rodded. NHBC spell it out https://www.nhbc.co.uk/binaries/content/assets/nhbc/tech-zone/nhbc-standards/tech-guidance/5.3/p261---tg-5.3---y-junctions_v1.pdf
