Mmm. In 1975 our estate was built using breezeblocks; it was meant to be a temporary thing when we moved in, our side of our home street having been subject to compulsory purchase (then again my parents made a profit on the deal, getting more for the house than they'd paid for it).

49 years later, the estate's still there. Proof that there is nothing in this world so permanent as a temporary emergency.

But at least the houses were rewired...several years after we moved in. Ever tried to replace a plug socket when the wires are solid copper instead of strands - and the copper's work hardened? I have. Can't recommend it.
