Anscombe employed a small office in Wellington which designed a range of work including residential apartments (Lyndfield and Olympus on Oriental Parade, Franconia on The Terrace (1938), Belvedere at the corner Austin and Majoribanks Streets), Hamilton Flats (Hawker Street) and commercial and institutional projects including: the Post and Telegraph Building, Herd St (1939), Dominion Motors, the Island Bay kindergarten, and the Lloyd St, Disabled Soldiers' Vocational Centre (1943). His work in the Hawke's Bay area included offices and a wool store for the New Zealand Shipping Co. Ltd at Port Ahuriri, Washpool Homestead, the Farmers Co-operative Association Building, Westerman & Co (1932), and the State Theatre (1933–34) with Vernon Brown in Hastings. One of his longest serving staff in this Wellington office was Mrs. Ethel Bulté, who was known as "Auntie Pat" by Anscombe's grandchildren. She was Anscombe's secretary and is remembered by the grandchildren as always wearing black, her "grey hair pulled back into a bun" with the appearance of being an "efficient secretary." She remained a friend of the family even after Anscombe died.
