A horizontal extension of an existing gravity bar above a historic, protected structure. Constructed in 1904, it was Ireland’s first mild steel building. The project followed the principles of minimal intervention and reversibility, reflecting best practice in the conversion of historical structures. The entire building was fully operational and open to visitors throughout construction.

This project used a creative strategy to adapt and extend an existing structure while ensuring the storehouse below, a protected historic structure, remained fully operational. This was challenging as the Storehouse has over 1.7million visitors each year.
The complex Gravity Bar extension was both a vertical extension of the 1904 building structure and a horizontal extension to a 1999 structure approached as a single intervention across the expanse of the roof.
The judges admired the detailing and the determined effort to respect the integrity of the original 1904 structure by minimising the level of structural interventions required.
The engineers worked closely with the architect on the design scheme and comprehensive analysis facilitated the roof top addition and helped minimise upgrade costs.
