My father, Roger FitzGerald, who has died aged 63, was a leading architect who chaired the national firm ADP for 20 years. Among other projects, he designed the only significant extension to the Palace of Westminster since the present structure was built in the 1800s. He was also a prolific painter who created four books and whose works fetched thousands of pounds at charity auctions.
Roger was born in Cambridge, the son of Desmond, a quantity surveyor, and Eileen, who worked in catering, and he took an interest in the city’s buildings at a young age. After leaving the Perse school, and studying at the Manchester School of Architecture, he started work at ADP in London in 1983. He stayed for 38 years. As chairman, he helped to expand the practice and turn it into an employee-owned organisation.
