Client: The Landmark Trust

Location: Llwyn Celyn, Monmouthshire


Restoration of a Grade 1 listed building and a series of historic barns, regarded by Cadw as one of the finest medieval hall houses in Wales. It has been continuously inhabited since it was built in the 1480s, the last occupants moving out in 2014.

On behalf of the client Wildwood Ecology:

  • Project management, including a preliminary roost assessment and a series of dusk emergence and pre-dawn roost surveys.
  • Identified the presence of a multiple roosts, including rare species bat (lesser horseshoe), within the main hall house and other historic barns.
  • Provided advice on the legal and planning policy issues and recommendations on how to address these.
  • Successful planning application to Brecon Beacons National Park Authority and subsequent mitigation licence to Natural Resources Wales.
  • Onward audit reports, discharge of planning and mitigation licence conditions and species monitoring to 2022.


The Landmark Trust has raised £4.2million to restore the site and carry out the associated programmes, including a 2.525m grant from the Heritage Lottery Fund. Planning permission granted in 2016 and works ongoing under close supervision by Wildwood Ecology.
