Brennan Furlong

Founded in 2015 by Gareth Brennan and Séamus Furlong, Brennan Furlong is an award-winning, internationally-recognised, RIAI-registered practice based in Clontarf, Dublin. A studio of 10, the practice has 7 RIAI-registered architects, a number of whom hold Conservation accreditation (Grade III).

Our Work

The work of the practice – a mix of residential and commercial projects – centres on the principle that the well-considered & carefully developed design of buildings and spaces we use every day helps to enrich and enliven our experience and interaction with the built environment.

Each project is viewed as a unique opportunity to collaborate with our clients and the design and construction team as a whole to develop the brief and maximise the potential of each site, incrementally improving our built environment, and our daily lives as individuals, families & communities.

The work of the practice has been published in a number of newspapers and magazines in Ireland such as The Irish Times, The Sunday Times, The Irish Independent, The Sunday Independent, The Sunday Business Post, Image Interiors, House + Design, The Gloss Magazine, House & Home Magazine, Plan Magazine & Irish Country Life Magazine with our Four Winds project featuring on “Room to Improve” on RTE Television in 2026 and our Yew Lodge project featuring on “Home of the Year” in 2022.

Internationally, the practice has been recognised through exhibitions, publications and online features. Our work “Howth: The Memory of a Site” formed part of the Time Space Existence exhibition in Venice which ran from May until November 2025. Our work was featured in Elle Decoration UK’s November 2025 edition. Online our work has been published on internationally-based platforms such as Architectural Record, ArchDaily, Architizer and Archello.

Selected projects by the practice have featured in the annual Irish Architecture Foundation Open House Dublin event, held each October, with the practice giving tours to the public of completed projects as part of Open House every year since 2016.

The work of the practice has also received recognition through various architectural and design awards and short-listings. In 2017 the practice won a silver medal at “Bloom” for “Space to Collaborate” designed in conjunction with Tricia Harris. In 2018 our Double Pivot project was awarded a Special Mention at the AAI Awards. In 2022 our Stiles Road project won the award for best House Extension / Refurbishment at the Building and Architect of the Year Awards. Various other projects have been shortlisted for the Irish Design Institute Awards, the Irish Concrete Society Awards, the Building and Architect of the Year Awards and have been selected for exhibition by the RIAI as part of their annual architectural awards. In 2025 our “Four Winds” project received a Special Mention in the international Architizer A+ Awards.
