We're protecting Britain's original smart home - one tile at a time. A £1.8 million project is underway to ensure this pioneering Victorian home stands strong for years to come.
The Gallery at the House is currently closed. During this time, the first internal phase of the roof project will take place with works to the room’s skylight. The Gallery normally provides access to the Drawing Room and Billiard Room. During its closure, we will be operating guided access to these rooms with a member of staff from a meeting point on the House forecourt.
The Armstrongs purchased Cragside in 1863 and built a small sporting lodge perched on top of a crag in the middle of a rocky moorland.
The home was extended over three decades by architect Richard Norman Shaw. When the Armstrongs set out to create their dream home, they set quite the challenge. They wanted to keep their original home and develop around it.
The House grew unconventionally. Years of phased extensions, combined with the introduction of Armstrong’s pioneering technologies, resulted in a spectacular design with an intricate footprint and dramatic exterior, topped with a complex roofscape.
The House's position against the crag, coupled with an elaborate multi-roof design, does not lend itself to dealing with heavy rainfall and storms. Climate change has exacerbated issues as milder wetter winters, heavy rain deluges, and more frequent storms overwhelm the water drainage system built for Victorian weather conditions.
The roof is a vast jigsaw with over 100 roof slants and multiple interconnecting roof ridges at different heights. The intricacies of the roof junctions trap water in hard-to-reach-places. Gutters overflow, and water runs down the side of the building, increasing the risk of water ingress, the emergence of salts, rotting timbers and interior leaks. Recent storms, some with wind gusts reaching up to 100mph, have also dislodged and knocked off roof tiles.
If left, these combined issues could weaken the building's structure and cause irreversible damage to the interiors and collections inside the House.
We're working with specialist contractors to repair the roof. It's a mix of terracotta, slate and glass skylights. At its tallest point, the roof is 26-metres (85ft) high and beyond this is a pattern of spiralling chimneys. To reach the roof safely and efficiently we will be installing a significant scaffolding structure. Work will include:
There are gaps and cracks in the roof tiling, making the House susceptible to leaks.
The roof is the building's first line of defence. Repairs will improve Cragside's resilience to climate change and ensure that this much-loved House is around for years to come.
This project will halt the deterioration of the roof which in turn will stop water ingress and leaks, protect the interiors and collections from damage, and slow the spread and development of harmful salts.
All bat species in the UK are legally protected, so it’s essential that our conservation work does not disturb them during their breeding season. To safeguard the colony, contractors will pause work from the end of May until the end of July to ensure their activities don’t impact breeding.
Seven of Northumberland’s bat species have made the House their home, with an eighth roosting in the surrounding woodland. Together, they make Cragside one of the most significant bat sites in the county.
Regular surveys have recorded Common Pipistrelle, Soprano Pipistrelle, Brown Long-eared, Brandt’s, Whiskered, Natterer’s and Daubenton’s bats swooping in and out of more than 140 exit points around the House. Although the exact number of bats tucked away in the building’s many nooks and crannies is difficult to measure, peak counts on warm summer nights have recorded over 100 individuals on the wing.
Bats tend to follow the same flight paths each night, so we’ve built additional space into the scaffolding to ensure they can move in and out of the building freely. You may also notice that the scaffolding hasn’t been wrapped in netting - this is to keep their established routes open and unobstructed.
If you have visited Cragside before, you will notice some changes during your visit while works take place. They include the reversal of the Carriage Drive and a re-entry system back on to the grounds.

We're currently working on information points about the project where you can read more about what's happening, watch videos and listen to pop up talks.
This project has been funded by the National Trust and by generous grants from Wolfson Foundation and Sylvia Waddilove Charitable Trust.

The scaffold structure is now complete. Because Cragside House is a Grade I listed building, the scaffold cannot be attached to either the House or the surrounding Rock Garden. Instead, it has been designed as a vast free-standing structure that supports itself.
As the House evolved over several decades, it has multiple levels, hidden corners and unexpected angles. Working around these features required an intricate scaffold design, complete with numerous platforms and vertical access ladders.
