An Elizabethan turret that helps define the roofline of Longleat House in Wiltshire is set to be repaired after long-term water ingress created conditions for wider structural damage, according to a report shared with Wiltshire Council.
The council has granted listed building consent for conservationists to carry out repairs to one of three octagonal lanterns and stair turrets, features designed by architect Robert Smythson in the 1560s. The turret is considered “of high significance,” and the approved repairs are expected to be completed on a like-for-like basis.
Experts told planners the turret has suffered from “long-term water ingress” through its exposed domed masonry roof and upper blind windows. The damp conditions also contributed to an outbreak of deathwatch beetles, a wood-boring pest that can damage timber, including beams and other interior structural elements.
The repair plan aims to tackle the root moisture problem and prevent repeat damage. Documents submitted to the council say the work will address water ingress, create a dry and ventilated turret space, and improve access so the area can be inspected and maintained more easily in the future.
For mason contractors and restoration crews, the project is a familiar reminder that high, exposed masonry elements can drive building-wide issues when moisture gets in. When heritage features sit out of easy view, planned access and regular checks matter, especially where roofs, domes, and openings take the brunt of wind-driven rain.
