The windows in the Queen's Robing Room were designed by J. Hardman Powell, son-in-law and apprentice of A.W. Pugin, the prolific genius of the Gothic Revival, who was directly responsible for huge quantities of designs for fittings and furnishings throughout the new Palace. After his death Pugin's style continued to influence the remaining work. The windows were manufactured in the Birmingham factory of John Hardman and Company. Hardman's partner in this enterprise was William Powell, whose son, John Hardman Powell became Pugin's only pupil.

The firm of Hardman was also responsible for most of the metal work in the Palace of Westminster, as well as wall decorations and embroideries. After Pugin's death in 1852, John Hardman Powell became the company's chief designer. But in the later 19th century Hardman's gradually came to concentrate on stained glass to the exclusion of everything else.
