Built between 1897 and 1909, the building is considered to be the greatest masterpiece of the celebrated architect.

The Grade A-listed library in Renfrew Street was destroyed in a fire in 2014 and is currently undergoing a multi-million overhaul to restore it as faithfully as possible.

The Hunterian at the University of Glasgow is home to the world’s largest single holding of the works of Mackintosh, which includes paper versions of his architectural, furniture and interior designs.

The plans will be amongst the first items from The Hunterian to move to the new state of the art collections study facilities at Kelvin Hall and will provide crucial detail for the restoration.

Page\Park were appointed as design team lead by GSA which is working with a large number of contractors and organisations on the project.

GSA’s senior project manager, Liz Davidson, said: “The GSA’s restoration team is very excited at the prospect of consulting afresh Mackintosh’s original plans and other documents relating to the building. Our aim is to meticulously restore the Mack, and access to the original documentation held at the Hunterian will help increase our understanding and appreciation of Mackintosh’s ground-breaking design.

Dr Robyne Calvert, Mackintosh restoration research fellow, added: “The research that has been undertaken by all the consultants in the Restoration Design Team has been meticulous. Although much Mackintosh’s architectural drawings are available online through the fantastic ‘Mackintosh Architecture: Context Meaning and Making’ project, not all are high enough resolution to make out fine annotations the architect made. Further, there are some drawings of furniture and fittings in the collection that the GSA must consult in order to ensure we are accurately reconstructing items that were lost to the fire.”
