The National Trust, who own The Charles Rennie McIntosh-designed Hill House, received the grant of £95,000 from the Getty foundation towards flood protection works to the exterior of the 113 year old building.

This includes the replacement of the Portland cement render, which has been cracking and letting water in.

The award comes through the Los Angeles - based Foundation's Keeping It Modern architectural conservation grants initiative, which will help the NTS carry out the works.

Simon Skinner, the chief executive of the National Trust for Scotland said: “This is an exceptional act of generosity by the Getty Foundation for an exceptional building.

“Last year’s events at the Glasgow School of Art were a salutary reminder of the preciousness and importance to architecture of Mackintosh’s remaining buildings. "Although many of the conservation challenges at Hill House stem from the original specifications, we are obliged for the sake of Scotland’s heritage to ensure that this striking and wholly innovative property is brought to the best possible condition for future generations to enjoy."

The Hill House was built for publisher Walter Blackie.

McIntosh wanted a cement render to give the building a modern look, but it didn't work, leading to water ingress, where flood water leaks into a building over a long period of time and weakens the internal structure.

Flood prevention works are expected to get under way later this year and into next year.
