Question

To ask the Senior Deputy Speaker what lessons from international heritage restorations, such as the Notre Dame Cathedral in Paris, have informed the planning, public engagement and delivery models for the restoration of the Palace of Westminster.

The R&R Programme has been engaging with and learning lessons from other major international heritage restoration projects.

Several other parliaments are undergoing or have recently completed renovation programmes of their buildings, for example the Canadian, Dutch, and Austrian parliaments. The R&R Programme maintains a dialogue with these other parliaments to learn lessons for our own restoration programme. One way it does this is through the International Network of Parliamentary Properties (INPP), an umbrella organisation of international parliaments which is dedicated to the conservation, restoration, rehabilitation and development of parliamentary estates. The INPP holds an annual conference and regular online seminars to share key lessons, which R&R officials routinely attend to learn best practice in how to plan, engage on, and deliver complex projects in a parliamentary context.

The R&R Programme has also learnt lessons from other non-parliamentary international heritage buildings, including a visit to the 400-year old stock exchange building in Copenhagen (after it was partially destroyed by a fire during refurbishment in 2024) to learn about matters such as fire risk during renovation and emergency preparedness. R&R officials also held a lessons-learned event about the Notre Dame restoration in May 2025 to understand better how the restoration works to the Cathedral were project managed, the use of technology in the project (such as the creation of a digital model) and the associated public engagement strategy.

Officials and Board members involved with R&R have also visited heritage restoration projects across the UK, such as Buckingham Palace and Manchester Town Hall, to learn lessons that are being practically applied during the planning stages of R&R, for instance in relation to surveys and engaging with the supply chain.
