Although I've not seen them myself, I've been told about an extension builder that builds the whole extension out of blocks with BG bonding
First thing put up block walls, wait a while then put on roof and then render the outside, all in one day. I'm assured that they do this on a regularly.

if anythin i would use dri-wall adesive its stronger done loads with it sets like concrete but suppose you could use hw and rake the joints back then rough it over it will all key together also airbrick empty voids like chimneys cause condensation

the reason for the airbrick mate it rain will still come down the chimley and damp will form.
you need to vent any area that has no air flow otherwise that area will sweat and cause condensation and other damp problems, also you must think about air flow say maybe? ( gas installations ect) where air flow is very important. especially when double glazing has been installed. ??? Worth a thought....

as mentioned earlier with rain ingress etc...
if the flue is to decommisioned as a vent for hot smoke from a real fire it wants capping at the pot anyway.. one that allows airflow or ... see above :
chinamans hat style clay vented cowl for a 89 inch pot is around 30 quid tops from most builders merchants, sometimes you have to give em a day or two to get one from another depot then you just get on the roof and drop it in the pot where it'll sit happilly...
ive never know one get blown off yet, even when the storms have had half he ridges off etc..
dont, whatever you do, block the pot end completely or the condensation will cause havoc...

do you mean bonding coat plaster or the stuff they use to glue blocks together with? like a thinbed mortar.. spread it and rake it up with a notch trowel and use durox blocks or similar?essexandy said:Although I've not seen them myself, I've been told about an extension builder that builds the whole extension out of blocks with BG bonding

building inspector aint gonna pass anything done with bonding plaster ???
someones either getting mixed up or had one too many down the pub :

I've only said what I was told by a chippy I've worked along side for years, every so often he come along and say "those rough b*stards did it again yesterday". He would be told to turn up in the afternoon to put on the roof trusses. The last extension I built the inspector came and checked the footings and then didn't come back until after the roof was finished , I could have built the place using peanut butter and he wouldn't have known. And as for bad advise I think there are plenty of others to moan at first before you start on me lucious. OH yeah I did mean carlite bonding Chris, but of course I'm not recommending it.Chris W said:do you mean bonding coat plaster or the stuff they use to glue blocks together with? like a thinbed mortar.. spread it and rake it up with a notch trowel and use durox blocks or similar?essexandy said:Although I've not seen them myself, I've been told about an extension builder that builds the whole extension out of blocks with BG bonding

I dont see a problem with blocking up a fireplace using hardwall as a s/c replacement. its not structural your just using it to stick 5 blocks together to fill a hole then hardwall and skim over the surface.
What is the issue in doing that?
Maybe i am full of s**t , I have done it and sleep easy.

seeing as this entire thread is about 'getting it done in a day'..
i cant see why people are thinking sand and cement to stick durox blocks together followed by hardwall half an hour later followed by a skim coat an hour after that cant be done? thats exactly what i do and the blocks dont fall over when i trowel the hardwall or skim on?
everybody knows durox suck like buggery so whats with the 'gotta use hardwall' thing all about?
chimneys/fireplaces are susceptible to moisture which will deteriorate hardwall but wont deteriorate sand and cement so who cares how long it takes to cure as long as it doesnt turn to mush if it gets damp?
last time i used a little bucket of premixed mortar from wickes? just add water? in a bucket? couldnt be arsed buying a bag of building sand and a bag of opc.. mornings work
i dont get it?
if its that much of a rush why not tack a duplex board to 4 bits of 2x2, gripfill it in the hole and one coat skim it... an hours work if you chuck a handful of cement in the skim..
