Ridge has been working at The National Gallery since 1994 on numerous projects including exhibitions, maintenance and major projects.

The Grade I listed buildings were completed in 1910 and occupy the north side of Trafalgar Square.

To date, the scope of works includes:

• Gallery refurbishments over a phased programme
• Re-roofing, replacement of existing patent glazed rooflights to galleries with internal laylights and new sunscreen installation
• Upgrading of conference facilities and displays, creating function rooms
• Upgrade of CCTV and security provisions
• Provision of accommodation for in-house contractors, releasing existing space for future development

Installation of new chillers for the Education Block and including an acoustic roof enclosure.
