The only architect appointed to the government's new Sustainable Housing Task Group (SHTG) has issued a warning over the central pillars of the Communities Plan.
Lynne Sullivan, a director of Broadway Malyan, said she believes many of the 'concepts' behind the proposals to solve Britain's housing supply problems are debatable.
The task group was unveiled at last year's Better Buildings Summit, and will advise the government on targets to ensure the massive housebuilding programme in the south of England will be sustainable.
However, Sullivan described aspects of the plan as 'arguable'.
'The government ought to be aiming at growth in the North, not just writing it off as a nongrowth area, ' she told the AJ.
'It also needs to be careful in the South, where it is aiming for major growth. There has to be a question of whether these targets can be achieved without the delayed major infrastructure investment.'
The Urban Design Group chair Ben Stone agreed. 'We are also concerned about the measures the government has set out for the North, ' he said.
'The plans could result in widespread demolition of the kind that became so familiar in the 1960s, ' he added. 'I think we should really have learned lessons from those mistakes by now.'
