[holding answer 2 March 2007]: No significant refurbishment works have been undertaken at 70 Whitehall and the Downing street complex since the large-scale rebuilding works that took place between 1960 and 1963. Much of the infrastructure at 70 Whitehall now needs to be renewed and/or upgraded, including ventilation and cooling systems, electrical transformers, and IT and telecommunications cabling, and we are also seeking to improve access and reception arrangements and other essential maintenance works. A decision has been taken to pursue necessary improvements through ongoing annual maintenance works. Planning permission and/or listed building consent will be sought where required. Any costs involved in the maintenance and improvement of the Cabinet Office estate will be included in the Cabinet Office accounts.
