Scaffolding for Historic Buildings

Scaffolding is an essential tool for the construction, maintenance, and conservation of buildings and structures. Scaffolding has been in use as long as people have been building. Modern scaffold structures can be larger and more complex than the buildings that they are serving, and the design and erection of scaffolding has become a specialist skill.

When scaffolding or other temporary works are used in, on, against, or in close proximity to historic buildings or monuments, there is a risk of damage from accident, carelessness, or inappropriate working methods. Practices that are commonplace when scaffolding modern buildings are not always appropriate when scaffolding a historic building or structure. Temporary works need to be carefully designed to avoid unnecessary damage to historic fabric.

Contact points between the structure and the scaffold are the main area of concern, whether at supports, restraints, or foundations. Drilled anchors are widely used across the industry, but are only acceptable in a heritage context if agreed in advance. Early consideration of alternatives is crucial, and early engagement with the Conservation Officer or Inspector of Ancient Monuments is strongly recommended.

This guidance provides an overview of the approaches and design issues that need to be considered when scaffolding or other temporary works is required for works to a historic building or structure. It is intended for building professionals and contractors involved in maintenance and repair projects, as well as planning and conservation officers involved with scaffolding proposals in a historic context. Reference is made to existing industry best practice and how this can be applied to historic buildings and structures. It focusses on building safe and stable scaffolding without damaging the historic structure.
