Bebarfalds have arguably become best remembered for its Bebarfald-BlueBird sewing machines, introduced around 1917 (though the Bluebird brand name did not appear until after this date) . Elegant timber cabinets made at Bebarfalds' furniture factory concealed British-made Vickers sewing machines, giving the impression of a substantial piece of furniture that would sit in harmony with other home furnishings. Bebarfalds offered customers free dress making courses and established an advisory bureau headed by Mona Moncrieffe. The c1929 catalogue, More frocks for less money (TC 646.1 BEB/2), is an overview of the services offered to sewing machine customers and suggests the success of the enterprise: a sewing machine factory was established in the Sydney suburb of Leichhardt and a new showroom set up in Collins Street Melbourne.

Bebarfalds also established a home planning bureau and in 1927 published a substantial volume, Safe home planning (TCQ 728.37 BEB). This book, subtitled 'the most complete and most authoritative book on home planning, building and furnishing ever compiled and produced in Australia', included contributions from a number of experts including architect Augustus Aley and landscape designer Max Shelley, and covered subjects ranging from purchasing land for a home to installing electricity, planning a garden and every aspect of furnishing the home. The bureau also offered a proto interior decorator service where customers could be supplied individually-tailored home furnishing schemes.

In 1929, the company constructed a new eight-storey building designed by architects Kent & Massie on the site of its old premises. The building still stands though two-storeys were added by 1967 resulting in the removal of the heavy cornice. About this time Bebarfalds considered expanding its business beyond home furnishings to include drapery, millinery and fancy goods but decided against this enterprise and sold off its unused drapery showcases in 1934. Instead, in 1931 the company invited Woolworths to open a new branch of its store across a section of the ground floor space.

Expansion of the business included the opening of new branches: in 1940, Bebarfalds stores were located at Newcastle, Parkes, Wollongong and Lismore, as well as a BlueBird sewing machine showroom in Brisbane. After World War II suburban branches were opened and by 1965 these included Parramatta, Cabramatta, Caringbah, Fairfield, Janalli, Maroubra, Stanmore, Sutherland and West Ryde. In the same year, however, Woolworths obtained the long-term lease of Bebarfalds city store and in 1968 the company was taken over by Ajax Insurance Limited. Bebarfalds’ suburban stores continued to trade under the Bebarfalds name until around 1973 when they became part of Macy’s Emporium (Sydney) Pty Ltd.
