Devonshire House, Mayfair
Thomann-Hanry®’s cleaning and restoration teams have worked intensively on the massive Portland stone elevations at Devonshire House, a landmark building located on Piccadilly.
Specialist Portland stone cleaning
Devonshire House is a Grade II listed mammoth Portland stone island office block designed in 1924-26 by the American practice of Carrere and Hastings with Professor Reilly.
The Portland stone building design falls under Glasgow-American classicism with sparing but lively Graeco-Roman details and has relief plaques, with flanking pavilions fully rusticated.
Portland stone cleaning was completed to all elevations using Thomann-Hanry®’s non-scaffold, dry and non-abrasive façade gommage®. Works took place separately to each elevation, all according to client’s convenience with minimal disruption to passers-by and the building’s occupants. Cleaning works were followed by stonework restoration.
