Steel delivering Dublin’s latest commercial development

Dublin’s commercial sector is set to receive a significant boost with the development of Harcourt Square; two inter-connected steel framed buildings, topping out at nine and seven-storeys respectively, that will provide 31,866m² of Grade A office space.

Designed by Henry J. Lyons for developer Hibernia REG, the best-in-class scheme has been described as an exemplar office scheme and will primarily be occupied on completion by KPMG, as the company’s new headquarters.

The 1.9-acre city centre plot is located on the south side of the River Liffey and was previously occupied by Dublin’s Garda (police) headquarters.

Working on behalf of main contractor John Paul Construction, Severfield is fabricating, supplying and erecting 3,500t of steelwork for the project.

Predominantly based around a regular 9m x 9m column grid pattern, the steel frame starts at basement. Above this level sits the lower ground, which accommodates a double-height auditorium in building A (the taller nine-storey block). This large space will be able to accommodate an audience of up 600.

Creating this column-free space is a 17m-long truss, which is one of the project’s largest single steel elements. Weighing approximately 30t, the storey high truss is positioned behind the area’s terrace seating and extends from ground floor level up to the underside of the first floor.

Harcourt Square is due to be completed in early 2026.
