The future of a £170 million regeneration scheme for a key site in Truro city centre is up in the air after councillors refused to grant planning permission. An outline planning application for the Pydar Street regeneration scheme went before the council’s strategic planning committee. But despite being recommended for approval by planning officers the committee decided to refuse permission over concerns that the development was too large and overbearing and concerns about a loss of parking spaces. The scheme is being led by Cornwall Council itself through its development company Treveth and has been hailed as one of the biggest and most ambitious schemes the council has ever been involved with.
