Ok here goes...the terracotta bricks we are talking about do have some thermal qualities if laid correctly in two separate rows(cavity wall construction) with the correct amount of cement to hold it all firmly( not the standard dib and dab Turkish method). Then insulation is placed in the cavity.
In 8 years we have seen one house in Turkey built like that and a few with Ytong (insulated concrete block) and hundreds built with single skin terracotta blocks (laid which ever way they think it will fit) with the minimum amount of cement required to stop the brick falling off!
There is absolutely NO thermal qualities about this building method.We have never heard anyone say that their house is warm built that way unless they have spent thousands of £'s to get a reliable form of heating installed.
As for £70 will sort out your utilities ....well it gave me a laugh but it will not cover your costs!
Good luck
