The Land Development Agency and housebuilder Castlethorn are to begin construction of a 562-home scheme in Dublin that will include a 30-storey tower, set to become Ireland’s tallest building.

The project received planning approval from Dublin City Council last year and is being delivered through the LDA’s Project Tosaigh programme. The completed homes will be owned by the LDA and made available as cost-rental housing.

The 30-storey tower is likely to become the most visible element of a rapidly changing part of Dublin, and its height marks a significant shift in the city’s approach to residential density around major transport infrastructure, with the Heuston area emerging as one of the capital’s key locations for large-scale redevelopment.

Construction at Parkgate Street, on the former Hickey’s Wholesale Fabrics warehouse site opposite Heuston Station and beside the entrance to Phoenix Park, is due to start within weeks, with completion expected in late 2029.

The centrepiece of the development will be Parkgate Pointe, a 30-storey apartment building containing 198 homes, while three interconnected blocks will provide the remaining 364 apartments, ranging from 10 to 13 storeys. John Paul Construction has been appointed to build the development.

“The 30-storey Parkgate Pointe will become a new landmark on Dublin’s skyline and is set to be Ireland’s tallest building,” LDA Chief Executive John Coleman said in a statement.

Parkgate Street is the second major development on which the LDA and Castlethorn are working together, with construction already under way on 328 cost-rental apartments at Castlethorn’s Woodbrook development in Shankill.

The project is one of the most significant developments yet to emerge around Heuston Station and is being positioned as the first major step in the wider regeneration of the transport hub and surrounding area. The scheme will also include retail and resident amenities, roof terraces and a communal courtyard. All apartments will have an A-rated building energy rating performance certification.

The LDA and Córas Iompair Éireann have also signed a memorandum of understanding covering the phased delivery of a mixed-use master plan for the Heuston Quarter, including new homes, offices, retail and public amenities.

“Pedestrian and cycle connectivity will be an important feature of our proposals, with a new boardwalk and cycle bridge linking the train station to Conyngham Road and the Phoenix Park,” CIÉ Group CEO Stephen Kent said in a statement.
