Home renovation with extension, garage and new waste treatment system

Ciara and Declan Gallagher and Kerins want to give their home at Creevymore, Cliffoney a major overhaul. They're planning to knock down some existing sheds and outbuildings, demolish part of the current house, and build a new single-storey extension at the back along with a garage. They'll also install a new wastewater treatment system to handle drainage.
