The intention of this competition winning redevelopment is to create a modern open-plan office development incorporating an array of sustainable features, in a historically sensitive area of Dublin city.

Located within the context of the three Georgian streetscapes of Fitzwilliam Street, Baggot Street Lower and Mount Street Upper, the new building is respectful of the surrounding Georgian area, reinstating the Georgian rhythm of Fitzwilliam Street by dividing the building into five blocks, to suggest the width of a historic Georgian house.

The five blocks vary in height from four storeys to Fitzwilliam Street Lower and Baggot Street Lower, rising to seven storeys within the heart of the site and onto James Street East. The main development consists of two interconnected office buildings, one will accommodate the ESB Head Office, whilst the other will be made available commercially. This flexibility within the design allows for single or multi-occupancy use.

The site is made permeable by the inclusion of a pedestrian route through the centre of the site from Lower Fitzwilliam Street to James Street East, connecting to a new public plaza at the south west corner of the site on James Street East. The development includes the mature landscape of seven sunken gardens and courtyards.
