An ambitious aparthotel in Dublin city centre

About the project

As part of the Mariott International Hotels hotel chain, 31-34 Abbey Street Hotel is an aparthotel consisting of 222 bedrooms. It is an ambitious construction that connects two buildings – one reaching 10 storeys, the other 9 storeys – with a basement floor that has access to both buildings.

Being a large building located on a main road in central Dublin means that much of the work will be confined to a small space to minimise the disruption to public spaces on the street.

IN2 was appointed for full M&E services, with much of the electrical expertise forming the design of the hotel’s new guestroom management system. With the two buildings serving different purposes – one acting as a hotel and the other as a long-term residential with self-catering facilities – the management system was designed to handle both environments.

The booking and management system is also connected to the energy system that controlled lighting, heating, and cooling. As the building can automatically turn facilities on and off, this ensures sustainable energy standards that minimise wasted energy as it is directly aligned with occupancy and use.

As well as the design of the guestroom and energy management systems, IN2’s contribution also included ensuring vehicular access via Great Strand Street to provide service access, the creation of 30 bicycle parking spaces, associated lighting, site servicing (full and surface water drainage and water supply), the provision of SuDS measures (including attenuation tank below ground and sedum roofs), PV panels, external plants at 1st, 7th, 9th floor and roof levels (including telecoms infrastructure at aparthotel roof level), and lift overruns at roof levels.

Due to confined space the majority of plant rooms were located in the basement. For this, IN2 have also ensured adequate mechanical ducts and ventilation in the basement to keep the plant rooms cool.
