Case studies
Maintenance of bat access in roof voids after fire door installations.
Fire doors were installed in the roof voids of three National Trust buildings in 2014: Bradenham Manor, Buckinghamshire, Claydon House, Buckinghamshire, and residential cottages at Greys Court, Oxfordshire. Bat roost access within and exit points from the now-compartmentalised roof voids were maintained by adding vent tiles and shuttered hatches.
Manchester Holiday Inn, Wilmslow (original case study requiring update)
Roost exclusion to prevent odours entering hotel bedrooms.
Manor Farm, Barley, Hertfordshire (original case study requiring update)
Three redundant barns were converted to three dwellings. Since they originally hosted a breeding Natterer's roost, a percentage of the original mortice joints were retained by means of recessed entrances with minimal glazing.
Mansion refurbishment (original case study requiring update)
Refurbishment scheme. This involved constructing a plant room in the building roofspace and removing approximately 10% of the area available to roosting bats.
Maudelyns Barn, Berkhamsted, Hertfordshire (original case study requiring update)
A redundant timber-framed barn was converted into a residential dwelling, with a ceiling inserted at tie beam level. Although a loft space was integrated into the conversion, this was not part of a site-wide mitigation program as no EPS licence was obtained. This case study presents the findings of post-development monitoring work at a site where a brown long-eared maternity colony returned despite the absence of any specific mitigation.
Natterer's maternity roost at Peckforton castle (original case study requiring update)
Peckforton Castle Hotel is a prestigious Grade 1 listed building; however the Bell Tower and West wing remained in its original condition for many years but was due to be refurbished to create additional hotel accommodation.
