dont have a pic of the corner but all you do is run the damp across into the cavity so its sandwiched when the corner block is laid. The brickie will know.
oh and if you do bring it down 100mm top and bottom 600 wide damp isnt enough you need 900.
we used the 'tony tray'. in reality the DPC doesn't rip, timber isnt sharp. Very easy to do, little more work for brickie but guarantees a seal.
i brought ours down 100mm and stuck the 'flap' to the blockwork as belt and braces.
sounds like your going to paying for moving it then, they have a valid paid for wayleave. doesnt matter if ownership changes it doesnt negate it.
pays never to skimp on legal searches.
cant see the difference, just do dew point calc to see where it is going to form in your makeup. cant see adding more insulation would make it worse though ?
does seem to be OTT size but then its going to be a rip off MCS installer so to be expected.
our new regs new build heating requirement came out at 29w / m2 with a -15C outside temp less than half of that at zero when i did the initial calcs, actual performance is a little better.
