The new office, to be developed in partnership with IPUT Real Estate, will be specifically designed to promote agile working which will “embed the best of working from home and the office”.

Over the past 12 months, ALG has appointed seven new partners and increased its lawyer numbers by 10 per cent. It now employs over 930 people, including 420 lawyers of whom 112 are partners, across six office locations.

The firm expects to create at least 50 new jobs in 2022, mostly in Dublin but also in Belfast and Dublin. It has also increased its annual trainee intake by 10 per cent and will hire 150 trainees over the next three years.

The redevelopment of its Dublin headquarters will see the building size increase by 36 per cent to 155,000 sq. ft. adding two new floors, rooftop landscaped terraces, a new atrium to encourage collaboration and an entirely new client floor at penthouse level.

The work will begin this summer and will be completed in 2024, with ALG accommodated at other IPUT properties during the redevelopment period, principally at No. 3 Dublin Landings and at The Exchange in the IFSC.

Managing partner Julian Yarr said: “Our office in the IFSC has been our home for over 20 years. In that time we have quadrupled in size. We now have the unique opportunity to rebuild our home for the future – for our clients, for our people and for the community we work in. It will facilitate our ambitious growth plans and will allow us to develop a new way of working – a more agile way of working – driving our business forward for the next 20 years.

“We are staying in our home in the commercial heart of Dublin. We have built fantastic relationships with our local community through our responsible business and pro bono initiatives. It was important to us and our people that we maintain those links.

“To support our broader climate goals, it was also essential to have the most sustainable building possible and we’re delighted we can achieve this with a net zero carbon rating. This will truly be a building built, in partnership with IPUT, for us, by us.”

Niall Gaffney, CEO of IPUT Real Estate, added: “Our focus is to provide our occupiers with the most-sustainable real estate in the Irish market that meets the highest global standards for efficiency and environmental performance. In line with this ambition, we are delighted to work closely with A&L Goodbody to create Ireland’s most sustainable building at North Wall Quay.

“This new headquarters will set the new standard for low carbon office development in the market, while also significantly enhancing the workplace experience for A&L Goodbody employees.”
