Dublin's tallest building, a 25-storey residential tower, has been given the green light.

Developer Johnny Ronan has secured planning permission for the apartment block on North Wall Quay in the docklands; 550 apartments are planned across three blocks as part of the Waterfront South Central scheme, which will include a restaurant and viewing terrace at the top of the tallest building.

Is high-rise the present and future of building?
