The urgent multi-million pound campaign to save Charles Rennie Mackintosh's Hill House has reached £1m.

After launching the appeal at the beginning of February, the National Trust for Scotland has surpassed the milestone and is headed towards its £1.5m target.

The campaign is taking place during the 150th anniversary of Mackintosh's birth.

Hill House will officially close to the public on Wednesday, July 4, as preparations begin for the construction of the "box" which will shield the property from weather for the next decade.

Key items of Rennie Mackintosh-designed furniture and fittings such as the iconic ladder back chair and dining room light fitting will be removed from Hill House when the building closes, to go on display in an exhibition in central Glasgow this summer.

The box will open to the public later in the year, celebrating the conservation of Mackintosh's masterpiece in full view of the public, with raised walkways enabling visitors to see every level of the house.

General manager for Glasgow and west at the National Trust for Scotland, Richard Williams, said: "The support we've had for the campaign has been incredible - people from across Scotland, the UK, and the world have donated what they can to save the Hill House.

"It is testament to the property's importance and Mackintosh's global appeal."
