In the past six years Triton have completed several phases of the conservation, cleaning and restoration of the Portland stone facades of this Grade I Listed building.
Designed by Sir George Gilbert Scott in 1861, it is notable for the variation of each façade.
Triton have undertaken, to date, work with a contract value of £2.7 million on the following elevations: Phase I - Central Courtyard, Phase II - King Charles Street, Phase IV - Downing Street , Phase V Triple Archway, Phase VI - Whitehall, Phase VII - Roof works, Phase VIII - Lightwell works.
All works have been carried out to a conservation grade specification that is broadly similar for each phase.
TBR poultices were used to remove existing ‘browning out’ stains, with the DOFF system and fine nebulous sprays used for all stone cleaning.
All repairs to the statuary was undertaken by our conservators, including the regrouting of fractures and the removal of anti-bird gel.
Extensive matching stone indents, carved in situ, were used to repair Corinthian capitals, columns and mouldings. Granite repairs and repolishing were undertaken as required.
All of the leadwork was reinstated to weathering details, as necessary, and to finish, all hardwood was repaired and redecorated, with a new anti-bird system installed to deter the pigeons.
