17-Storey office  development providing 213,000  sq. ft. exemplar Grade A office accommodation in arguably the best location in Belfast City Centre. The listed Ewart Building is the only remaining part of the former Ewart’s linen manufacturing complex, dating from the late 1800’s and will be sensitively restored. 

The historic building and the new build structure will be linked at first and second floor, grouped  around  a central courtyard. When fully occupied the two buildings will have capacity to accommodate  some 2,000+ employees. This project was awarded Commercial Development of 2022. 




This Project is a great example of bringing the old charm of Belfast and new technologies together. It provided a comprehensive refurbishment and extension of a 150 year old former warehouse. 

AEM faced some complexities when installing appliances in the plantroom as space was limited, however with caution and precision this was done successfully.

Another issue AEM faced on site was deliveries. As the project was located in city centre, the team had to coordinate deliveries against traffic, in order to successfully finish the project on time. AEM also had to modify the installation to comply with NI Architectural Heritage Department and avoid destroying the fabric on exterior of the building, as well as the historical features in the interior. 


Parliament Building

NI Assembly
Hamilton Architects
Electrical & Mechanical


Parliament Buildings, Stormont, built in 1921 and officially opened in 1932, is a grade B+ listed building and recognised as one of Northern Ireland’s great architectural set pieces.

Sir Arnold Thornley designed the building with perfect symmetry and symbolism, such as the building being 365ft wide, representing one foot for every day of the year; and having six floors and six pillars at the entrance, one for each county in Northern Ireland.

Parliament Buildings is home to the Northern Ireland Assembly, in 2014 The Assembly Commission appointed contractors to repair and refurbish the entire roof of the 95 year old building.

AEM where appointed the M&E Contractor on this magnificent building. The overall Mechanical & Electrical Building Services  was £1.6million.  The project from start to finish was 12 months and was completed on time and within budget.

The Mechanical works included :- replacement of external roof mounted HVAC plant with packaged air handling plant, refurbishment of boiler plant rooms, replacement of BEMS controls, provision of rainwater harvesting systems, renewables installation to include solar thermal, heat pumps and photovoltaics and meter installations

The Electrical works included :- alterations to existing main switchgear, new sub mains distribution cabling, general power installations, power & control wiring associated with new HVAC plant, alterations to lightning protection, general emergency & maintenance lighting, electrical metering installations, alterations to fire alarm and alterations to CCTV installations.

The works proved to be challenging as all work was carried out in a fully operational and restricted environment, ensuring no disruption to the Assembly Chamber, Assembly Business and Public Tours.

Working in this ‘Listed Art Deco’ building (One of Five in Belfast) we found many complexities which had to be overcome. Complex issues included the building being located on the edge of the River Lagan at the back and also on the side of a major road at the front. This meant that all deliveries had to be planned and at certain times Vehicle Management Systems had to be put in place to ensure safety. Further complex issues were the fact that the existing front elevation had to be retained and that no M&E Services could puncture the fabric of the building. Periodic meetings took place with all parties to ensure that the programme of works could be met and that all works could be completed as per the specification given.
