Project specification

  • We were asked to inspect the school buildings and produce a 10-year PPM schedule relating to the fabric and structure of the properties.
  • PPM reporting was completed in accordance with the current industry practice, including the RICS guidance note: Planned Preventative Maintenance of Commercial & Residential Property.
    • Given the historical nature of the buildings, the need for conservation repair was included alongside consideration of when items will need replacement or renewal.
  • The buildings included:
    • a large mansion building, built around 1682, consisting of red brick with lavish stone dressings and slated Mansard roofs
    • A brick clockhouse, dating from 1709. Both of these buildings were Grade 2* listed
    • the school’s theatre block, which was built in the late 20th century.

Key survey findings

  • Our report incorporated an overview of the historic significance of the listed properties, the survey records, and the PPM schedules.
  • We made several recommendations, including some urgent structural works that, if left unresolved, could cause considerable damage.
  • Costs for items of repair ranged from £50 to approximated £30,000.
  • Although the total expenditure required to restore the properties and maintain them was over half a million, we were able to advise on how those costs could be spread over the 10-year PPM period.
  • Costs were categorised according to the risk priority and urgency to aid planning and decision making.
