Industry body Homes for Scotland has been joined by consultants in claiming that too much reliance is being placed on previously allocated sites that were undeveloped even in boom times.
The organisation's head of planning strategy Blair Melville said Strathclyde and Edinburgh are burdened by expectations around land values and developer contributions which render most of the sites unviable. "Neither region shows any signs of understanding how they can alter course," he complained.
Barton Willmore Edinburgh director Stephen Tucker maintained that the number of unsuitable sites being allocated could jeopardise future growth.
Meanwhile, Geddes Consulting's appraisal of the emerging Edinburgh and South East Scotland strategic development plan has concluded that most local authorities will not meet their housing requirements without substantial additional land releases.
