ICF vs double block cavity construction

[deuce22]

Does anyone know the difference in cost between these 2 methods. A friend has recently built a property using ICF and said it was similar in cost to a property he built using a double block cavity construction.

I've only had a quick look and this doesn't seem correct.

 

Thanks.

Does he cost the labour for both?

Is this comparison being made just on materials?

 

The impression I had with ICF is that the self builder has the opportunity to do more work themselves.

He did the labour himself for both projects, so for him it was just materials.

I would have to pay for a bricklayer, but would construct the ICF myself. Labour for block work will cost me £1 per block.

I've spoken with a company called Thermohouse and they've quoted me £41 per m2. I've just done a quick costing for my garage and for blocks including Labour it comes to just over £5500 and with ICF it came to just over £6000. I have to add the cost of a concrete pump, so it will possibly be around £1000 more. Even though there is liveable space above the garage, the majority of it is not and so it's probably a bit of a waste of money using it for the garage.
