2019: National Trust for Scotland surrounds Charles Rennie Mackintosh's Hill House in Helensburgh with a giant steel box to protect saturated walls and allow drying.

The National Trust for Scotland's conservation project for Charles Rennie Mackintosh's Hill House in Helensburgh is progressing as planned, with a giant steel box surrounding the property since 2019 to protect its saturated walls and allow drying. Samples from the house indicate it is gradually drying out, and experts will take further samples from the interior in April. The next major milestone, the removal of the external concrete render, is planned for late 2024.
