20 Kildare Street, Dublin

20 Kildare Street is a premium new seven storey over basement office development, including the renovation of four Heritage List Period Buildings on Kildare Street, Dublin 2.

Barrett Mahony Consulting Engineers acted as Civil & Structural engineers for this project from inception through planning, tender and construction, through to completion. The project encompassed the design of a reinforced concrete shell with post tensioned concrete floor slabs. The post tensioned slabs allowed long spans removing columns to provide a more open floor plate.

The site was an extremely tight inner-city location with a narrow access off School House Lane. From the start of the design process access and deliveries of construction materials needed to be considered, and early engagement with the contractor helped develop a design suitable for the site.

As part of the development, four 18th Century Georgian heritage listed town houses fronting on to Kildare Street were renovated. Prior to the works, the condition of these buildings varied, with some semi-derelict. The works to these buildings were meticulously developed with the heritage architect so as to retain as much of the original fabric and details as possible.
