Some 330 historic prefabricated homes in Bristol are set to be demolished later this year, following a failed bid to have them listed.
Both campaigners and locals are distraught that the houses - erected throughout the city as part of the post-1945 building boom - are to be replaced by modern council apartments.
Prefab expert and author Greg Stevenson - an adviser to the Twentieth Century Society - said he was 'gutted' that the homes would soon be knocked down.
'It is a tragedy, ' he told the AJ.
'They were a highly important part of Churchill's efforts to solve the post-war housing crisis. These buildings are part of our wartime heritage and yet the government claims they are not historical.'
And he has won the support of the Prefab Protection Society. This week it launched a campaign to prove the homes' popularity with residents and local architects.
But Kalim Anwer, a historicenvironment caseworker at the DCMS, dismissed the criticism, insisting they 'do not possess sufficient special interest, either architecturally or historically'.
