GLASGOW SCHOOL OF ART ARCHITECTURE: CHARLES RENNIE MACKINTOSH'S DEFINING WORK

The Glasgow School of Art — now formally known as the Mackintosh Building — is one of the most important works of architecture produced in Britain in the past two hundred years. Designed by Charles Rennie Mackintosh (1868–1928) while he was a junior draughtsman at the Glasgow firm of Honeyman & Keppie, it was built in two phases: the central section and east wing from 1897 to 1899, and the west wing from 1907 to 1909, by which time Mackintosh had been made a partner.

The commission came through a design competition launched in 1896 by the school's formidable headmaster, Francis Newbery. Honeyman & Keppie won on the basis of Mackintosh's design — though because he was still only an assistant, the building committee corresponded with John Keppie, and Mackintosh's name is almost absent from the official record. The initial budget was a tight £14,000, donated by the Bellahouston Trust, which forced construction to halt after the first phase. The eight-year gap proved to be an architectural gift: the west wing is measurably more advanced in its abstraction than the east, and the celebrated Library — generally regarded as Mackintosh's finest interior — was only possible in the redesigned second phase.

Beloved as "the Mack" by generations of students and staff, the building suffered devastating fires in 2014 and 2018. It currently stands as a shell, wrapped in a protective membrane, with its rebuilding one of the most significant cultural conservation challenges in Britain.

What is the Glasgow School of Art?

The Glasgow School of Art was founded in 1845 as the Glasgow Government School of Design — part of a national effort to improve the quality of applied arts and craftsmanship for British industry. By the 1890s, under Francis Newbery's direction, it had become one of the leading art academies in Europe and had outgrown its accommodation in the McLellan Galleries. Newbery pushed for a purpose-built home on a new site at Renfrew Street, on the steep hillside of Garnethill, in central Glasgow.

Mackintosh himself had attended the school as an evening student during his apprenticeship — meaning the building he designed was, in a very real sense, his alma mater. He understood the brief from the inside: generous studios flooded with consistent north light, practical workshops in the basement, a library for research and study, and circulation spaces that made the whole building feel purposeful rather than monumental.

The result is a building that is simultaneously a functional teaching institution and one of the most original architectural compositions of its era.

Architect: Charles Rennie Mackintosh

Charles Rennie Mackintosh (1868–1928) designed the Glasgow School of Art while still a junior draughtsman at Honeyman & Keppie — meaning the building that would become his masterpiece was created before he had achieved partnership or independent recognition.

Mackintosh had trained as an evening student at the School of Art itself during his apprenticeship, giving him an intimate understanding of the brief. Working alongside his wife Margaret Macdonald — whose contribution to his interior schemes was substantial and long underacknowledged — he developed a distinctive design language that synthesized Arts and Crafts tradition, Scottish vernacular architecture, Japanese aesthetics, and emerging European modernism.

The Glasgow School of Art established Mackintosh's international reputation, particularly in Vienna where Josef Hoffmann and the Secessionists regarded him as a peer. However, British recognition came more slowly. By 1914 he had effectively stopped practicing architecture, worn down by limited commissions. He died in London on 10 December 1928, aged 60, in relative obscurity. His full reputation was only established posthumously, growing most significantly after Glasgow was named European City of Culture in 1990.

Architectural character and design approach

The Glasgow School of Art resists easy classification. It is often described as Arts and Crafts, or Art Nouveau, or proto-Modernist — and it is all three and none of them entirely, which is part of what makes it remarkable. Mackintosh worked from the functional requirements outward: the building's character is generated by its purpose, not imposed upon it.

The shallow E-shaped plan maximises natural light in the north-facing studios, which require consistent, diffuse daylight for artistic work. The main Renfrew Street façade is an asymmetric composition of eight bays — seven large studio windows with deep reveals and organic wrought-iron brackets, the entrance set slightly off-axis at the head of a flight of steps, the headmaster's room carried on an oriel window above, and a stair tower rising above the roofline like a Scottish castle turret. The stone is Giffnock sandstone, a warm golden-pink ashlar, which gives the building a solidity the glazed bays then counteract.

The west wing, completed a decade later, is markedly more severe. Where the east wing retains traces of historical reference, the west elevation — with its vast projecting studio windows — is closer in spirit to the European avant-garde of 1909 than to anything being built in Britain at the time. The two halves read as a coherent whole from Renfrew Street, but they represent a decade's worth of architectural evolution compressed into a single building.

The Library

The Library, housed in the west wing, was universally acknowledged as Mackintosh's greatest interior. A double-height room lit by three tall projecting bay windows on the west elevation, it was organised around a rhythm of dark-stained timber posts and beams, with a Japanese-influenced clarity of construction and a balcony carried on projecting brackets around three sides. The hanging light fittings — designed by Mackintosh — were among the most admired objects in the building. Every detail, from the joinery to the reading desks to the card catalogue, was designed as part of a coherent whole.

The Library was destroyed in the 2014 fire. A historically accurate recreation — using original timber species including longleaf pine and tulipwood — was already largely complete when the 2018 fire destroyed it for a second time. The loss of the Library is the defining wound of both fires.

The fires and what was lost

The 2014 fire broke out on 23 May during degree show installation, started by expanding foam ignited near an old film projector. Heroic efforts by students and firefighters saved the majority of the building — approximately 90% of the structure survived — but the Library was destroyed and the archive suffered water damage.

The 2018 fire struck on 15 June, while a £35m restoration was in its final stages. The sprinkler system had been delivered but was weeks from commissioning. The second fire was catastrophic: it burned through the night, consuming all surviving interiors and leaving the outer walls so structurally unstable that large sections of the south elevation had to be dismantled to prevent uncontrolled collapse. Emergency services received the first call at 11:19pm; 120 firefighters and 20 appliances responded. No cause was ever formally established.

The contrast with Notre-Dame de Paris — gutted by fire in April 2019 and largely restored by December 2024 — has been drawn repeatedly and pointedly by those campaigning for faster action on the Mack.

The path to rebuilding

The building is a Category A listed structure — the highest designation under Historic Environment Scotland — and the GSA has committed to its "faithful reinstatement" as a working art school rather than a museum or ruin. The building is currently wrapped in a white fire-retardant membrane, installed in 2023 to allow the sandstone shell to dry out. A new protective roof structure is in place.

In July 2024, the Glasgow School of Art appointed Reiach and Hall with conservation architects Purcell to update the Strategic Outline Business Case for the rebuild, taking account of construction inflation and changes to Glasgow's city centre development plans. That report is expected in 2025. Separately, arbitration with the building's insurers over the 2018 fire claim is ongoing — the outcome of which will significantly shape the finances of any rebuild.

The original 2030 target for full reopening is now considered unlikely, and the total cost is expected to exceed the £62m figure previously cited. The restoration remains the subject of intense advocacy from architects, alumni, cultural organisations, and members of the public in Scotland and internationally.

The model-maker's lens

We chose to model the central portion of the Renfrew Street façade — the north elevation — because it is the face most people know.

  • Focus — the central entrance set slightly off-axis at the head of steps, the oriel window above carrying the headmaster's room, and the stair tower rising above the roofline.
  • Detail — the ironwork is where Mackintosh's invention is most visible.
  • How it reads at small scale — the ironwork is necessarily simplified but its presence gives the model a handcrafted quality appropriate to the subject.
  • How to display — best displayed facing straight on, where the façade geometry and the interplay of windows and solids is clearest. The slight asymmetry of the entrance makes it interesting to view at a small angle too. Natural light works best, reading the shadows cast by the deep window reveals.

There is something particularly charged about modelling this building now. The Mack exists as a shell, wrapped in protective fabric, at the centre of a complex and unresolved restoration process. The model keeps the building as it was: solid, purposeful, and present.

Frequently asked questions about the Glasgow School of Art

Who designed the Glasgow School of Art?

Charles Rennie Mackintosh (1868–1928), working as a draughtsman within the practice of Honeyman & Keppie. Because he was not yet a partner when the competition was won in 1897, the official records name Keppie rather than Mackintosh — one of the more remarkable attribution stories in British architectural history. Mackintosh went on to become a partner in 1901, by which point the first phase was complete. He is also known for the Hill House in Helensburgh, the Willow Tea Rooms in Glasgow, and a body of furniture and decorative work that made him a central figure in the European Art Nouveau movement.

When was it built?

In two phases: the central section and east wing from 1897 to 1899, and the west wing from 1907 to 1909. The eight-year gap between phases allowed Mackintosh to develop his design considerably — the west wing, with its monumental library and deeply abstract north facade, is markedly more radical than the east, and the two halves together chart the arc of his architectural development.

What is the address?

167 Renfrew Street, Garnethill, Glasgow G3 6RQ. The building occupies a steeply sloping site, which Mackintosh exploited to dramatic effect: the north facade on Renfrew Street rises sheer from the pavement, while the south side steps down through multiple levels to Scott Street below.

What is its listing status?

Category A listed (Historic Environment Scotland listing reference LB33105) — the highest tier, reserved for buildings of national or international importance. It is also included on the World Monuments Fund Watch list and has been the subject of international advocacy following the fires.

What happened in the fires?

A fire in May 2014, caused by expanding foam ignited near a projector, destroyed the Library and damaged the west wing. The Library had been considered one of the finest interior spaces in British architecture. A second, catastrophic fire in June 2018 destroyed all surviving interiors while a £35m restoration was in its final weeks — a loss described by Historic Environment Scotland as irreplaceable. The cause of the 2018 fire was never formally established.

Will the building be restored?

Yes — faithful reinstatement as a working art school is the Glasgow School of Art's stated goal. As of February 2026, the building is wrapped in a protective membrane, architects Reiach and Hall with Purcell are preparing a rebuilt business case, and insurance arbitration is ongoing. The timeline remains uncertain. The project is among the most complex historic building restorations currently under consideration in the United Kingdom.

What architectural style is it?

It does not fit neatly into a single category — it draws on Arts and Crafts, Scottish vernacular tradition, and the European avant-garde. The east wing and entrance facade show the influence of historic Scottish tower houses and Baronial architecture, while the west wing in particular anticipates the abstraction of early Modernism. The Charles Rennie Mackintosh Society describes it as the defining work of the Glasgow Style — the distinctively Scottish strand of Art Nouveau that Mackintosh, his wife Margaret Macdonald, and their contemporaries developed in the 1890s and 1900s.
