The last complete piece of the lost royal Palace of Whitehall
Built for King James I in 1622, Banqueting House is last complete piece of the lost royal Palace of Whitehall. Designed by Inigo Jones, it’s now home to the only surviving Rubens ceiling in its original location in Europe. Coniston, as main contractor, delivered a major refurbishment programme including complete flooring replacement, new passenger lift installation, full M&E re-servicing and environmental upgrades directly beneath the Grade I-listed Rubens canvases. The works ensure the building’s preservation while enabling step-free public access for the first time.
Working beneath a masterpiece
The project required wholesale replacement of the 1960s oak flooring and substructure, installation of a new passenger lift in the North Annex, and comprehensive M&E upgrades – all executed immediately beneath Rubens’ priceless ceiling panels with zero tolerance for damage, vibration or dust. Historic Royal Palaces needed net-zero-ready environmental controls (air-source heat pumps, Whitehall District Heating reconnection) and improved temperature/humidity stability to safeguard the 400-year-old canvases without visual intrusion into Jones’ classical interior. The scheme balanced major structural interventions with conservation imperatives in a nationally significant, fragile Grade I environment.
Precision delivery in a fragile heritage setting
Coniston managed a tightly controlled programme of strip-out, structural alterations and reinstatement directly under the Rubens ceiling, using temporary propping, dust extraction and vibration monitoring to protect the artworks. The existing floor was lifted to upgrade heating pipes and services, revealing archaeological finds last seen in 1964, before laying a new sustainably sourced English oak floor sympathetic to the 17th-century architecture. A new passenger lift was formed within an existing North Annex pit, enabling step-free access to the Main Hall for the first time. Rooftop air-source heat pumps and District Heating reconnection delivered precise environmental control, while asbestos removal, deteriorated fabric repairs and new lighting rigs completed the works without scaffold intrusion into the hall.
Access, preservation and performance
Banqueting House now offers step-free public access to the Rubens ceiling via the new lift, with stable environmental conditions protecting the canvases for generations. The upgraded M&E infrastructure is net-zero ready, while the new oak floor unifies the Main Hall aesthetically and archaeologically. Coniston’s delivery demonstrates controlled, highly technical execution in a fragile heritage setting, unlocking the building for wider public and event use while preserving its status as a masterpiece of classical architecture.
