Project to dry out Charles Rennie Mackintosh's Hill House at ‘critical' stage
The property in Helensburgh, Argyll and Bute, which was built in the early 1900s, has been badly affected by rain damage.
www.independent.co.ukI can summarize the latest public updates I’m aware of, but I don’t have live access right now to pull the very newest articles. Here’s what has been reported recently about The Hill House (National Trust for Scotland) and its conservation program:
Recent conservation work has focused on stabilizing and drying the building after long-term water damage. A major development reported in early 2026 indicates progress in the drying process as part of ongoing restoration efforts. This aligns with the National Trust for Scotland’s long-running Mackintosh Illuminated project and aims to reduce the need for protective containment in the future. [Source coverage from 2026 reporting on the project’s critical drying stage][1]
The Hill House has historically required protective measures to shield it from rain while conservation work proceeds. A long-running “box” enclosure around the house was introduced in 2019 and, according to recent reports, the aim has been to remove such containment once the structure is sufficiently stabilized and moisture is under control. The most recent updates describe steps toward reintroducing external conditions to the building as it dries and repairs proceed. [BBC and related coverage on the box and its removal timeline][2][4]
The Hill House is at the center of a high-profile fundraising and heritage initiative. The National Trust for Scotland and partners have run appeals and funding drives to support comprehensive works, with timelines that extend into the late 2020s. This includes collaborations with lottery funds and heritage organizations to ensure the building’s structural and design integrity is preserved for future generations.

For context, the Hill House is Charles Rennie Mackintosh’s iconic residence in Helensburgh, celebrated for its design innovation and its role in architectural history. Ongoing conservation work is framed as essential to safeguarding this international design heritage asset. [NTS overview and history][6]
