Councillors in Kerry are to begin procedures to delist a seafront house in Knightstown on Valentia Island.
The delisiting is against the advice of planners who said the house is an integral part of the historic village.
The owner of the building local builder, Mr Séamus Lynch of Chapeltown, plans to demolish the house and build an entirely new structure.
Dungail House was included in the record of protected structures in the county development plan adopted by councillors late in 2003.
The core of the building, opposite the pier on Valentia, dates to the 1850s.
However, it is probably much older, according to the report circulated to members of the council. It is a link to the time when the slate quarry was in operation and was most likely connected to the quarry and used as offices. Internally, it is well preserved with an original staircase and doors and sash windows to the front. Later additions date from before 1900.
Knightstown was designed by the Scottish engineer Alexander Nemmo, well known for his work on Irish lighthouses, in 1839 and is one of only two planned towns in Kerry.
"The building is therefore an important part of the town's seaside setting, forming a unity with the New Cable Terrace built in 1914, the Old Cable Terrace, built in 1865, the Presbytery built in 1880 and the Royal Pier Hostel built between 1850 and 1870," the planners wrote.
Dungail House contributes "to the appreciation of the entire seafront as a contemporary architectural element", they added. They also said that the listing of the property does not preclude the owner from carrying out development work.
