We are delighted to announce that Duggan Brothers (Contractors) Ltd have been appointed main contractor on the upcoming development of Leeson Lane office building in Dublin 2, on behalf of the OPW. The completed project will operate as a flexible, multi-occupancy government headquarters and will be an exemplar for energy efficiency.

The project is funded by the Office of Public Works . On completion, the development of this brownfield site will act as a flagship office development for the OPW, being space efficient and compliant with nZEB, while restoring and safeguarding a fine example of built heritage into the future and enhancing the urban realm.

The project involves the restoration and refurbishment of historic Spruce House, a former dispensary building, and the construction of a new 7-storey office building, linked to the rear of the dispensary building at ground and first floor levels. Site development works also involve the reinstatement of the historic laneway Leeson Place.

In compliance with the European Energy Performance of Buildings Directive, the new building has been designed to achieve nZEB (nearly Zero Energy Buildings) standard with a very high energy performance. The building will be predominantly naturally ventilated, and a significant amount of its energy requirements will come from renewable sources. Use of heat pump technology and the application of the OPW’s Green Procurement Policy will further mitigate the climate change impact of the project. All EU regulatory requirements in relation to building material inputs, waste management and the re-use and recycling of waste materials have been incorporated into the project works requirements.
