i looked at these last build, the problem with them is it makes you screed the floor before the walls go up as they are not a workable surface for loading out. So you have to get underfloor etc all in before the roofs on which doesnt work. maybe a shed build where roof goes on quick they could work.

never bother grouting. cant see point of it.

mini piles are cheapest and quickest, need a ringbeam etc. Screw anchors any digger driver can install but they are double the cost of piles. abc anchors can supply quickly, they use https://www.mapl.co.uk/ to design them.

how are you going to add the DPC and make it continuous into the blockwork without taking the floor up ? Why wasn't the floor insulated when it was built, building control would have required it ? Ventilation is a requirement and a warranty fail if the missed or vents not installed. Do you have a new build warranty already ?

DO NOT do this. There has to be a minimum 150mm air gap from the underside of beam. Insulation goes above the floor not below it.

lots of low quality repointing. external walls arent structural, any cracks on inside ?

no need for fancy steel doors. It needs an external door frame with cill so you can can use normal 'front door' type rubber seals to seal it. can use a normal internal FD 30 door with intumescent strip routed into it.

its a false saving getting watertight in weeks if you dont get a completion cert for another 12 months remember. Same as the expensive shed builds. Unless the trades are lined up to machine gun the build out in 8/12 weeks its burring cash for no reason.

perhaps my English isnt good the key word is, O V E R D R A U G H T You are paying using borrowed money same as a credit card.

When paying with borrowed money you are covered by cca. Martin Lewis brought it up ages ago. So easy to fully protect yourself when doing a bank transfer.

paid a small amount on either a debit card linked to an account with an overdraught or bank transfer from same account. Either way you would be fully protected.

No consolation I know but a shame so may people still get had when its soo easy to protect yourself.

slim down to a 150 cav, have a look at recticel tongue and groove insulation. superior than celotex sheets.

you had to pay cash ?

are there any rads as well ? could explain dirty water .... Bleeding loops, especially long ones, takes a good while. It's an all day job on our last place as there was a lot.

just remember going to lawfare will take months/years and you will not have a completion cert in the meantime. You cant insure using a normal home insurance etc wood for the trees.

did you pay any amount to them on a credit card or debit card when you were using an overdraught ? If so claim off the bank.

im really just following the NHBC spec for capping a parapet wall, albeit you wont need the cavity closer. https://nhbc-standards.co.uk/7-roofs/7-1-flat-roofs-and-balconies/7-1-17-parapets-and-guarding-to-terraces-and-balconies/

unless its your forever home, take advantage of your good fortune and sell it.

before putting the coping stones back on run a length of dpc along it, cut it so its 5mm wider than wall to shed the water.

i looked at this and decided better off spending on a battery as you can be flexible with how you use the stored electric. Heat battery are 1 trick pony.

that is buildzone warranty underwriter.

concrete pan tiles are easiest and cheapest, some look really smart as well. Marley deo edgemore for example. Much more robust than clay or slate with none of the overlapping to worry about. Forgiving to cut at valleys/hips etc.

if your that worried pay the money and do it properly. you cant have your cake and eat it.

its only going to be there for a couple hours while you get signed off. Think outside the box.
