Ecoterrace Design Quality Presentation

  1. 2. Setting the context <ul><li>North Staffordshire Housing Market Renewal Pathfinder Area (RENEW North Staffordshire) </li></ul><ul><li>Intervention areas </li></ul><ul><li>- Areas of Major Intervention (AMIs) </li></ul><ul><li>- General Renewal Areas (GRAs) </li></ul>
  2. 7. RENEW Key Facts Although some of these facts relate specifically to Stoke on Trent, the issues are reflected in the other intervention areas across North Staffordshire. <ul><li>Between 1999 and 2003, Stoke on Trent lost 1,450 residents a year </li></ul><ul><li>In the last 50 years, the population of the old Six Towns has halved </li></ul><ul><li>7000 homes (4.3%) across the conurbation are empty. In central areas this rose from 7.7% to 9.4% during 2005 </li></ul><ul><li>If new build and clearance continued at past rates, it was estimated that there would be a surplus of 20,000 homes </li></ul><ul><li>The original RENEW prospectus recommended 14,000 properties be cleared and replaced with 12,000 new build properties. However, the clearance figures have now been greatly reduced </li></ul><ul><li>If economic and Housing Market Renewal strategies are successful, it is estimated that we will stop losing population by 2011, and bring the number of empty properties down to a normal level by 2021 </li></ul>
  3. 8. Chesterton General Renewal Area <ul><li>Predominantly pre 1919 terraced-type properties </li></ul><ul><li>Lack of investment into private sector stock </li></ul><ul><li>Empty properties </li></ul><ul><li>Failing retail units </li></ul><ul><li>Poor environment </li></ul>
