Onehunga Community House is a Category 1 heritage building at 83 Selwyn Street in Onehunga, first built in 1901 as the Onehunga Primary School. It is made of kauri wood in a Queen Anne style, and Heritage New Zealand classed it as a Category 1 heritage building in 2016. The house has five rooms of different sizes that community groups and individuals can book, for one-off events such as birthdays, weddings and baptisms, or for recurring classes such as pottery, yoga and karate. Tours and event bookings are also offered. Ritchies Museum is inside the house, with 719 books, booklets and newspaper supplements in seven subject categories. A reviewer reports that the museum is open on Thursdays from 10am to 12.30pm.
Reviewers praise the high ceilings, natural light and airy rooms, and say the windows open for summer cooling and ceiling heaters keep the rooms warm in winter. One reviewer said the accessible car park and restroom have been improved. Reviewers have held a wedding, a graduation party and a child's first birthday there, and one attends yoga classes regularly. Some mention the old bathroom and kitchen as part of the house's charm, and one praised the caretaker as hospitable. The kauri panelling and the high ceilings of an old school building are what make the house a venue for both events and classes.
