Isabel Maud Chambers was born in Roehampton, London, England in 1896 and trained for five years as an architect at the Architectural Association Schools in London from where she received her Diploma in 1923.
Chambers was the first women to receive the AA Essay Prize for her 1921 thesis on the 'Aesthetics od Stage Design'. She was awarded the RIBA Educational Silver Medal in 1923 and the inaugural Bernard Webb Travelling Studentship in 1924 subsequently spending three months at the British School in Rome. In 1924 she was elected an Associate of the Royal Institute of British Architects (ARIBA). During the 1920s she wrote a series of reviews of theatre performances for the AA Journal.
In 1926 she married the architect George Checkley (1893-1960). She appears not to have practised as an architect after the late 1920s. Her name is not listed in the Kalendar of The Royal Institute of British Architects after the 1928-29 edition.
Her address was given as The Priory, Roehampton, London in 1923 and 1926. She died in Nottingham, Nottinghamshire on 14 June 1941
