Proposed works
- Description of works
- Conversion of house into 7 apartments.
- Type of impact upon the roost
- Long-Term Roost Modification and Roost Loss
Proposed mitigations
- Type of mitigation
- Compensation
- Specific technical detail of measure
- Bat house. To build a bespoke bat building for lesser horseshoe bats, to compensate for the loss of the roosting space in the roof space of Hampton House. The new building’s primary function is to provide a summer roosting site which is capable of accommodating a small maternity roost in the long term.

- Bat house. To build a bespoke bat building for lesser horseshoe bats, to compensate for the loss of the roosting space in the roof space of Hampton House. The new building’s primary function is to provide a summer roosting site which is capable of accommodating a small maternity roost in the long term.External wall consists of double skinned cavity wall, made of concrete blockwork. The cavity wall is to provide thermal stability in the building, with most thermal variation in the roof space. The ground floor internal wall is constructed from Thermolite blocks to keep the ground floor cool and buffer external temperatures. 40m from the existing roost. Building size: 5m by 5m. Roof void height: 2.5m. Concrete block, thermolite block, wooden cladding, slate tiles.
