1916 heritage groups have vowed to appeal planning permission to demolish parts of Dublin's Moore Street for a new shopping, office and residential development.

Dublin City Council has granted two applications to develop Moore Street and part of Henry Street.

The National Monument at Numbers 14 to 17 would be preserved to be developed by the Government as a museum.

However 1916 relatives have criticised permission to demolish other parts of the terrace such as Numbers 18 and 19, which would make way for an archway entrance to a new public plaza.

Developers Hammerson rejected a request from Dublin City Council to consider making the entrance at ground level only, similar to the entrance to Meeting House Square from Eustace Street in Temple Bar.

In their reply to the council, Hammerson said this would obstruct visibility into the public space and would not encourage pedestrian movement.

They agreed to a less intrusive design for the archway which has now been given permission.

James Connolly Heron on behalf of The Moore Street Preservation Trust expressed "deep disappointment" that he decision had ignored the vote of city councillors to preserve the terrace from Numbers 10 to 25.

"This is another significant blow to the unique heritage of Dublin which is increasingly under attack by developers."

Councillor Donna Cooney (Green) said she will also be appealing the decision to An Bord Pleanála.

She said "the decision to grant permission for the demolition of buildings on the corner of Henry Street and Henry Place - our busiest shopping street - to widen a lane is unbelievable".

"The people working in those shops didn't even know this was on the cards," she said.

Additional information has been asked for a third application concerning the northern end of Moore Street because of concerns about loss of daylight for existing residents.

The three applications are the first of six to be made by Hammerson for the Dublin Central development which also includes the old Carlton site on O'Connell Street.

Original plans for a massive shopping centre were scrapped and the amount of retail was reduced to less than 10% of the amount originally planned.

The new plan has 44,000 square metres of office space, 210 hotel rooms and 94 apartments.

The plan envisages a new east-west pedestrian street between O’Connell Street and Moore Street and two new public squares.
