Inception & Reputation

Gunn Lennon Fabrications started in 1988 in Shanowen Road, Santry, Dublin. It was led by Eugene Gunn who had been the Chief Design Draughtsman in Smith & Pearson, the first Curtain Wall company in Ireland. Along with a small team, Eugene established the new company and served as Managing Director for many years. Gunn Lennon Fabrications grew quickly and under Eugene’s expert guidance it became a leader in the Irish curtain wall and commercial window industry. Over many years it has developed a reputation for excellence in design and quality.

Growth & Investment

In 2014, Eugene retired as Managing Director and a new team of Directors was appointed to lead the company, including Pádraig O’Dwyer as Managing Director, Paul Gunn as Technical Director and Adrian Davis as Finance Director. They were later joined by Barry Gough as Operations Director and Greg Donaghey as Commercial Director. After 29 years in Santry, GLF embarked on an ambitious expansion plan. Having acquired a building in Swords Business Park, a complete refurbishment and fit-out was carried out in order to create a new state-of-the art facility for the company, and in May 2017 the company moved to its new HQ.

An Eye to the Future

The new fabrication plant provides over 2,700 m² of factory space along with large storage areas. The two-storey offices provide modern facilities for design, engineering and production planning. The location close to the M1 offers easy access to the motorway network, the Airport and to Dublin Port. GLF now offers a wide range of metal and glass façade solutions, including both unitised and “stick” curtain walling to the Irish and UK markets. With recent and current projects ranging in value from €4 million to over €30 million, GLF is well placed to serve the needs of the modern construction industry and looks forward to continued future success

What Our
Clients Say

On behalf of the John Paul Construction site project management team I wish to record our appreciation of the efforts made by GLF on the new St Vincent’s Private Hospital. Delivering this project on time, on budget and to the highest quality standard is a testament to all involved.

Bruce Lupton Smith,

John Paul Construction

Eugene Gunn, has been known to me personally and the practice of Scott Tallon Walker for the past 40 years. I initially met Eugene during his time as a senior designer for the steel window company Smith and Pearson circa 1966. From the outset we were aware of Eugene's design ability, which was of immense help during the initial and conceptual stages of window and facade design. This passion has continued since the formation of his own company Gunn Lennon Fabrications Ltd some 22 years ago. Eugene’s desire for buildability and robust design, while achieving the architectural intent has led to a very successful working collaboration between Gunn Lennon Fabrications and the office of Scott Tallon Walker over the past four decades.

Owen Stynes,

Operations Director, Walls Construction

Gunn Lennon Fabrications (GLF) served as the facade subcontractor for the College Square development, playing a pivotal role in realising the architectural vision for this complex urban project. From the outset, the GLF team established a collaborative atmosphere, with weekly design workshops becoming cross discipline problem-solving adventures. GLF offered pragmatic robust solutions, never having to be reminded of the “design intent”. Their technical adeptness was particularly evident in the execution of the unique glazed terracotta facade. The bespoke tile profiles integrated into a unitised curtain wall system, demanded significant precision and quality control, dealing with a material subject to dimensional and visual tolerances. On site, the process was smooth, with the diligence of factory fabrication, brought to site, and the same level of pro-active problem solving and attention to detail. This is not said flippantly, after all, as the Republic of Ireland’s tallest habitable building, the quality of work is visible from around the city! GLF’s contribution was fundamental to delivering a facade that stands as the defining architectural feature of College Square. I genuinely look forward to collaborating with GLF on future projects.

Robert Salmon,

Studio Director, HJL Architects

BDA have worked for many years with Gunn Lennon on some of the most remarkable buildings in Dublin and its surrounds. We have always found their team to be very professional, able, and willing to take on the challenges the projects have presented. For College Square, the complexity of the facade required incorporating large, unitised curtain wall panels, floor to ceiling high performance glass units and bespoke glazed terracotta tiles, all in a selection of bold colours. The facade created many engineering and design challenges during the design development stage and on through to fabrication, and finally on site for installation. All issues were met head on by GLF in full collaboration with the Design Team, for the successful execution of this monumental building in the heart of the city, which currently stands as Irelands tallest residential building.
