Open House Dublin returns this October with its annual invitation to step inside buildings that rarely welcome the general public — and this year, TU Dublin’s Grangegorman campus stands among the programme’s most compelling destinations. Working alongside the Grangegorman Development Agency, TU Dublin will open three of its most distinctive buildings for guided tours: Lower House, the Central Quad, and the newly opened Academic Hub & Library.
The tours offer something genuinely rare: a first-hand look at how one of Dublin’s most historic sites has been redeveloped into a modern university campus without erasing its past. Whether you are an architecture enthusiast, a Dubliner curious about what has been happening behind Grangegorman’s walls, or a prospective student weighing up where to study in Ireland, each 45-minute visit rewards the time invested.
Places are limited and every tour operates on a pre-booked basis, so it pays to act early. Reserve your place on the TU Dublin Grangegorman tours through the Open House Dublin website before the slots fill.
Why Grangegorman Deserves a Place on Your Open House Dublin Itinerary
Grangegorman occupies a unique position in Dublin’s architectural and social history. For more than 150 years, the site was home to the Richmond Lunatic Asylum, later St Brendan’s Hospital — at its height, the largest psychiatric hospital in Ireland. Rebuilding the area as a campus for Ireland’s first technological university posed a considerable challenge: create a functioning, contemporary higher-education environment on a scale rarely seen in the city centre, while protecting structures of genuine historical significance and finding new purposes for them.
The result manages both. Restored nineteenth-century buildings now sit beside large-scale contemporary architecture, and this year’s Open House Dublin programme captures that contrast better than almost any other single location in the city. The three tours, taken individually or together, present three distinct readings of the site: its architectural and institutional history, the scale and ambition of the modern university, and the deliberate weaving of the two.
Lower House: A Restored Landmark with Two Centuries of History
Chronologically, the story begins with Lower House, one of the oldest buildings on the Grangegorman campus and a natural first stop for visitors.
From the Richmond Lunatic Asylum to a Working University Building
Designed by Francis Johnston, Lower House opened to patients in 1814/15 as part of the Richmond Lunatic Asylum, which grew into the largest psychiatric hospital in Ireland. After years of disuse and considerable deterioration, the protected structure was carefully restored as part of the wider campus development and reopened in 2021. Its survival and reuse illustrate the founding principle of the Grangegorman project: the site’s architectural past should remain an essential part of its identity rather than be swept aside.
What Visitors Will See Inside Lower House
Today, Lower House serves an entirely different role. During the tour, visitors move through refurbished spaces that now include dining areas, student common rooms, a dance studio and gym facilities. The visit also reveals part of the building’s 18 music practice rooms, alongside student and staff areas. For anyone interested in adaptive reuse — giving historic buildings genuinely useful new functions — Lower House is a case study best examined in person rather than in photographs.
Central Quad: Seeing the Scale of a Modern Technological University
From historic restoration, the tour moves to the opposite end of the spectrum: the sheer scale of the contemporary university.
The Largest Building on the Grangegorman Campus
Designed by Fielden Clegg Bradley, the Central Quad covers approximately 36,000 square metres and accommodates around 6,500 students and 400 staff. Six storeys rise above a large basement containing teaching kitchens — a detail that hints at the breadth of disciplines taught within the building, which ranges from science and engineering to hospitality. Few single buildings in Ireland house that variety of activity under one roof.
Highlights of the Central Quad Tour
Visitors enter through the main entrance and follow the building’s main circulation staircase, which acts as the vertical spine of the structure. The route continues across the first floor, taking in large lecture theatres, interior artwork and other key spaces normally reserved for students and staff. For prospective students and their families, the tour offers a realistic picture of day-to-day life inside one of the country’s most substantial educational buildings — useful context when deciding where to study.
Academic Hub & Library: Where Grangegorman’s Past and Future Share One Address
The final stop is the newest addition: the Academic Hub & Library, designed by O’Donnell + Tuomey Architects. Here, contemporary university life and another significant chapter of Grangegorman’s history come together within a single building.
A New Building Built Around a Protected Structure
The Academic Hub incorporates the restored North House, built between 1848 and 1854 as part of the Richmond Lunatic Asylum and later associated with St Brendan’s Hospital. Rather than standing apart from the new development, the protected historic structure has been incorporated into the Academic Hub & Library, with the new building wrapping around it. That design decision makes the relationship between old and new impossible to miss.
Inside the Hub: A Shared Space for the Whole Campus Community
The ground floor has been designed as shared space for the wider Grangegorman campus community. It houses a learning commons, café and community space, alongside student and staff supports including Academic Supports, Careers, Maths Learning, the Academic Writing Centre and Disability Supports. An exhibition space will also feature archive and display material from the Royal Irish Academy’s Grangegorman Histories Project — a valuable stop for anyone interested in the site’s social history as well as its architecture.
The Tour Route: Moving Between Old and New
The tour climbs from the ground floor through the library, which occupies the first to fourth floors, before crossing back into the historic North House. Visitors then descend through new student and staff areas, completing a route that moves deliberately between the campus’s two eras within a single building.
Tour Times, Booking Details and What to Expect on the Day
All three tours take place on Saturday 17 October, with departures at 10am, 11am and 12pm, and each lasts approximately 45 minutes. Visitors are welcome to enjoy all three tours or to select whichever one suits them best. Pre-booking is essential — no walk-up places are available on the day.
A few practical points will help the visit run smoothly. Arrive ten to fifteen minutes before your scheduled slot, wear comfortable shoes (all three tours involve stairs and a fair amount of standing), and note that the buildings sit in different parts of the campus, so allow walking time between tours if you book more than one. October weather in Ireland is unpredictable, so bring an extra layer.

Three Buildings, Three Perspectives on One Story
Taken together, the tours offer three complementary readings of Grangegorman. Lower House reveals the site’s architectural and institutional history. The Central Quad demonstrates the scale and ambition of the contemporary university. The Academic Hub brings those two worlds together under one roof.
That is what makes this year’s Open House Dublin programme at TU Dublin worth more than a brief visit. The buildings tell a larger story about the area: a historic site being given new life as a place of education, creativity and community, while its architectural past remains an essential part of its identity. Few locations in Ireland tell that story so directly, and fewer still open their doors to the public so readily.
Make a Day of It: Open House Dublin and the Wider Grangegorman Area
Because each tour lasts around 45 minutes, there is ample time in a single Saturday to complete all three visits and still explore elsewhere on the Open House Dublin programme, which features notable buildings across the city. The campus sits within walking distance of Stoneybatter and Smithfield, both of which reward a slow wander, and the wider Grangegorman area continues to add new public spaces, cafés and facilities as the development progresses.
Readers who want to follow the campus as it grows can keep up with the news articles and event listings published regularly by TU Dublin covering developments across its Dublin locations. Browse the latest updates to plan future visits, open days and public events.
See a Changing Part of Dublin Before the Doors Close Again
Open House Dublin provides an opportunity to see parts of TU Dublin that are normally experienced only by students and staff — lecture theatres, libraries, music rooms, student spaces and historic interiors. For one Saturday in October, the doors are open to everyone.
Book the tour that interests you most, or commit to all three for the fullest picture of the campus. Reserve your place through the Open House Dublin website, and if the visit prompts questions about courses, admissions or campus life, the TU Dublin team will be glad to help.
