Inside Deloitte’s new Dublin offices at

1 Adelaide Road

"We are creating a space where people can do their best work, but also feel supported in how they work."


Caítlín Flanagan, Sustainability Lead, Deloitte Ireland.

For 150 years, Deloitte Ireland has helped to shape the story of Irish business. From family enterprises in a newly industrialising Ireland to helping some of the world’s largest organisations navigate an age of AI, geopolitical uncertainty and commercial challenges, our organisation has evolved alongside the country itself. Now, another chapter is beginning to rise above the capital’s skyline.

At 1 Adelaide Road, Deloitte’s future offices are taking shape. It’s a workplace designed around people, around their wellbeing and sustainability, as well as the increasing focus on helping clients navigate transformation. The new building itself has become part of that story.

Modern Deloitte office lounge with green seating, circular ceiling lights, and open workspaces.

It represents the opportunity to create a workplace that genuinely reflects the values and ambitions of Deloitte today. From the outset, sustainability, wellbeing and flexibility were treated as fundamental design principles, not something considered later in the process.

Caítlín Flanagan, Sustainability Lead, Deloitte Ireland.

“We wanted to create a space where people can do their best work, but also feel supported in how they work, whether that’s through access to natural light, spaces designed for focus and quiet, better air quality, active movement, or environments that incorporate nature and support different sensory and working needs. The building has been designed around people as much as operational performance.” It’s a significant ambition.

The project is targeting some of the newest and most rigorous versions of building standards, a combination of which is achieved by very few buildings in the country. Our teams are pursuing these standards, with more demanding criteria around decarbonisation, energy efficiency, material health and long-term operational performance.

In practical terms, that means a fully electric building powered by renewable energy, designed to eliminate reliance on fossil fuels entirely supporting our ‘Net-Zero by 2040’ ambition with a LEED Platinum and ILFI Zero Carbon status. That means smart systems that reduce energy demand. It means sustainable materials chosen not only for performance, but for their embodied carbon impact and potential reuse.

But perhaps the most interesting part of the story is that the building has been designed around how people actually work and live. Across the country, the debate about the future workplace has often become trapped in binaries: office versus remote, flexibility versus collaboration, productivity versus wellbeing. Deloitte’s new headquarters is focused on creating an environment designed to support different ways of thinking, focusing and interacting.

The WELL Platinum standard places human experience at the centre of the design. It focuses on everything from air and water quality to acoustics, movement, light and thermal comfort. There are spaces designed for collaboration and energy, but equally spaces designed for quiet, concentration and decompression. Biophilic design principles, integrating natural elements into the environment, aim to strengthen people’s connection to nature and improve overall wellbeing.

Neurodiversity has also been consciously considered throughout the planning process. Flexible workspaces, sensory-aware environments and purpose-built quiet areas are intended to support a wider range of working styles and individual needs, recognising that high performance is rarely one-size-fits-all. Even during our interim office move, sustainability considerations shaped decision-making, with our teams transporting furniture, white goods and existing assets into temporary spaces rather than replacing them, part of a broader focus on circularity and reducing waste across the full lifecycle of the move.

With over 1000 items of furniture brought to the interim space this has equated to 145 tonnes CO2 equivalent mitigated through material reuse, the same as roughly 237 roundtrip passenger flights between Dublin and New York!

This project is about investing in a workplace designed for the next era of professional services, one shaped by AI, evolving client expectations and a deeper understanding of human performance and wellbeing. And, as we mark 150 years in Ireland, it is also about creating a headquarters that reflects the scale of its ambition for the next 150.
