Charles Rennie Mackintosh's domestic masterpiece is set to reopen to the public after work to enclose it in a "box" to protect it from the elements.

Hill House in Helensburgh was said to have been seriously deteriorating inside and out because of the effects of a century of driving rain and wind.

The National Trust for Scotland has spent five months enclosing it in a protective cage, calling it an "innovative solution" to saving the building.

The "box" will act as a giant semi-transparent shield covering the entire building and is designed to allow the garden within to continue to grow and for the building to remain visible.

Public access to the building will begin again on Saturday, June 8.
