The noble Lord makes an interesting point about the use of Parliament as a whole Estate, not just separate Houses and buildings. Accommodation surveys show that there is a significant amount of accommodation potentially available in Victoria Tower. It will be for the Houses to determine how to use that space after R&R has taken place. The future location of the archive is also a matter for the House administrations, which is currently being dealt with by the archives relocation programme.
The Joint Committee on restoration, in its report of September 2016, considered the possible use of Victoria Tower Gardens during the restoration. It said that they are likely to be required as a site for construction activities, such as plant, all of which are likely to have significant implications on traffic flows in and around the Palace. What consideration is being given to keeping Victoria Tower Gardens open and available for that period?
The noble Baroness has raised an important point, highlighting just how constrained the Palace of Westminster will be as a site, once we start getting into the full restoration project. In February this year, the sponsor body wrote to the Holocaust memorial planning inquiry to request that, whatever is ultimately decided, consideration is given to mitigating impacts on access to the Palace, both from the construction of any memorial site and also its future operation.
