The housing and homelessness charity’s vital hub was among the businesses impacted by the Union Street inferno.

The blaze, which started on Sunday afternoon, caused the partial collapse of the 19th-century B-listed Forsyth building.

Firefighters battled throughout the night to control the flames, which also led to the temporary closure of Glasgow Central train station.

No casualties have been reported, and the station itself appears to have survived with any damage.

Shelter Scotland director Alison Watson said: “We are heartbroken by the devastating fire on Union Street in Glasgow. Crucially, everyone who was in our Union Street shop is safe. The shop was evacuated as soon as the alarm was raised, and our team are now being supported by colleagues.

“We have been part of the Union Street community for nine years and our hearts go out to all the businesses and community members that have been impacted. We would also like to extend our sincere thanks to the emergency services whose calm and professional response ensured the safety of everyone present.

“On Friday, we had just completed some upgrades to our Shelter Scotland shop and delivered a new range of donated goods to sell. The shop has been completely destroyed, which is a major blow to our efforts to raise funds to fight the housing emergency.”

Anyone who wishes to support Shelter Scotland at this time can help by visiting one of its other shops or by making a donation online.
