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 20^th century.

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.
