New planning policy guidance PPG3 gives those local planning authorities who do not want developments to go ahead "valuable ammunition" to pursue that agenda, according to <b>Professor Stephen Crow.</b> Crow, who last year chaired the panel that recommended 1.1 million new homes be built in the south east, told the conference that - apart from some possible fine tuning - PPG 3 was here to stay. "PPG 3 is there, the product both of technical consideration and political input," he said. "If we can't learn to love it, at least we must learn to live with it." Crow argued that the concept of "land recycling", mentioned in PPG3, is crucial to the success of the urban regeneration programme. But he said that this did not just mean building on previously used land. "We must be thinking about recycling buildings," he said. "When they come to the end of their useful lives they should be torn down and redeveloped." Crow also called for a real dialogue on design between housebuilders and planners. "To my mind the PPG calls for fresh thinking which marries the best of architectural innovation with the demands of the market." <br>
