The school moved to its present location near the intersection of Gower Street and Keppel Street in 1929 CE. A competition to design a new school building to be sited in Gower Street, was held involving five architects, all experienced in laboratory design and construction. This was won in 1925 CE by Morley Horder and Verner O. Rees who located the main entrance in Keppel Street. The foundation stone was laid in 1926 CE by Neville Chamberlain, then Minister of Health, and the completed building was opened in 1929 CE by the Prince of Wales, later to become Edward VIII. The purchase of the site and the cost of a new building was made possible through a gift of $2m from the Rockefeller Foundation.
