Councillors in Tralee have voted overwhelmingly to delist part of an early 19th century Georgian building from the record of protected structures against the advice of An Taisce.
The annex to 18 Denny Street, at the side of the Southern Health Board offices, is part of a five-bay fronted building and it faces the large green and rose garden that is the town park in Tralee.
The building, including the wing, was listed on the grounds that the entirety of the building was of special architectural, historical, archaeological, artistic, cultural, scientific, social or technical interest, An Taisce said in submissions to the council.
Subsidiary wings were common with late 18th and early 19th century Georgian buildings.
"However, in this case the wing not only contains service accommodation, but also rooms with substantial windows, in this case three large Wyatt windows immediately adjoining the house," Mr Ian Lumley, heritage officer wrote to Tralee Town Council.
The council had deferred delisting at last month's meeting so they could get a historical description of the building.
On Monday night last, nine of the 10 councillors at the meeting during the discussion said it was of no architectural significance.
"Demolishing it would enhance the whole street," Cllr Ted Fitzgerald (FF) said proposing the delisting. The town council had never intended it should be listed, he added.
"It looks terrible from the street. The new development would finish off the street," Cllr Johnny Wall (FF) said seconding the proposal.
Cllr Cathal Foley (SF) said it was "an eyesore".
Cllr Tommy Foley (Ind) who voted against the delisting on Monday said: "I strongly oppose any de-listing in a historical street, one of the most attractive in the country."
Mr James O'Shea and Mr Ned O'Shea, owners, said they had plans for offices and overhead apartments and they provided a report with computerised images.
A spokeswoman for An Taisce in Kerry last night said they were "appalled" by the decision and it was to be raised at a meeting of the branch later that night.
