Ireland’s architecture is a rich tapestry of vernacular craft, foreign architecture and, most importantly, good ol’ grit. Like any nation, Ireland’s complex history is easily contextualized through its urban makeup. Take Dublin and Cork, for example. Both cities contain a wealth of Georgian and Victorian structures that directly speak to the republic’s past ties to Britain. All it takes is a quick tour of the extant churches, libraries and courthouses to understand how significant British and European influences were on the nation, including its architecture.

Foreign influences continued to inform Ireland’s built environment well after the Partition. In the 20th century, Irish designers turned to modernism and other international trends, this time on their own terms. Art Deco, Brutalism and sleek Modern structures began to appear around the country, generating an architectural expression to mirror the republic’s newfound independence. This modernist sensibility carried through the 20th century alongside a revival of the vernacular. Ireland’s traditional architecture — specifically the thatched cottage — was again made popular by tourists seeking a quintessential ‘Irish experience.’

Today’s designers continuously engage with discourse surrounding nationalism. What is the quintessential ‘Irish experience’, and how does it inform today’s architecture? With a built environment rooted in pluralism, Irish architects have an incredible opportunity to recreate and rectify an architectural language that best represents today’s Irish folk.

With so many architecture firms to choose from, it’s challenging for clients to identify the industry leaders that will be an ideal fit for their project needs. Fortunately, Architizer is able to provide guidance on the top design firms in Ireland based on more than a decade of data and industry knowledge.

How are these architecture firms ranked?

The following ranking has been created according to key statistics that demonstrate each firm’s level of architectural excellence. The following metrics have been accumulated to establish each architecture firm’s ranking, in order of priority:

• The number of A+Awards won (2013 to 2023)
• The number of A+Awards finalists (2013 to 2023)
• The number of projects selected as “Project of the Day” (2009 to 2023)
• The number of projects selected as “Featured Project” (2009 to 2023)
• The number of projects uploaded to Architizer (2009 to 2023)

Each of these metrics is explained in more detail at the foot of this article. This ranking list will be updated annually, taking into account new achievements of Ireland architecture firms throughout the year.

Without further ado, here are the 25 best architecture firms in Ireland:

FKL architects is committed to contemporary design with a focus on the application of abstract ideas to built form. Each project is approached from first principles by responding to the specifics of site and program and formulating a singular concept that informs all aspects of the design. This individual concept is firmly rooted in the pragmatics of the project.

We seek to condense ideas to their essentials, from the building form to the detail of junctions between materials with all decisions re-affirming and complementing the primary concept. The form and language of each project grows out of this approach leading to a diversity in the work, within a framework given by enduring interests; in space, atmosphere, assemblage, pattern, hierarchy, texture and materiality.
