Overend returned to Melbourne in March 1933, and soon was elected as an Associate of the
RVIA. He was then offered a partnership with his old firm, which became
H. Vivian Taylor, Soilleux and Overend in May 1933. Important examples included the Windsor Theatre, Windsor, 1936, the Padua Theatre, Brunswick, 1937, and the Regal Hartwell, cnr Camberwell and Toorak Roads, Camberwell, 1937, all now demolished. Other commissions included a series of service stations, and a series of houses. The Armytage House, Mont Albert Road, Balwyn, 1933, was noted by the
Australian Home Beautiful for the simplicity of materials, and he sweeping concrete stair 'apparently unsupported' and expressed on exterior by a curved corner tower (demolished in 1980). While working at Taylor & Soilleux, and drawing on influences from his time working under Wells Coats in London, he designed
Cairo Flats in 1935, a two story block of flats in Melbourne, for which he is best known. The project was halted with the
Japanese bombardment of the city in September, which Overend reported on extensively for the Australian press. He then travelled to London, working again for Wells Coates, but soon came back to Melbourne. In 1939, he began designing The Koornong School, located in
Warrandyte, which offered a new type of education. Here he used flat or skillion roof light timber buildings, arranged organically in the bush setting. In 1941, Overend designed the remarkable
Carrington Park, Elizabeth Drive,
Rosebud, for Leonard and Muriel Moran, of the
Moran & Cato retail chain. The main floor of the house is elevated on a thin concrete platform, and consisted of an entirely glazed frontage that wrapped around a circular 'observation deck' at the north-west corner, with narrow 'catwalk' balcony with pipe handrails. The windows have since been altered. Overend was also a prolific writer, contributing regularly to the column "Architecture and Property" in
The Argus,
Australian Home Beautiful,
Table Talk, and a variety of other esteemed publications through the 1930s. With a forward-thinking approach, Overend consistently provided insightful commentary on innovations, highlighting their practical applications and advantages. His writings served as a valuable resource for designers and homeowners, offering them guidance and inspiration to adopt and implement these advancements in their projects. Through his writings, Overend played a significant role in shaping the discourse around modern design and construction practices in Australia. In 1938 Overend was one of four architects appointed to the Victorian Architect's Panel advising the new
Housing Commission of Victoria, where he advocated prefabricated housing solutions. The commission began experimenting with the technology by 1939, using it for most construction by the early 1960s. == Military service ==
