Riccarton House is an historic building in Christchurch, New Zealand. It is part of the Riccarton estate, the first area in Christchurch lived in by British settlers, after which the suburb of Riccarton is named. The house was commissioned by Jane Deans, the widow of Canterbury pioneer John Deans, and finished in 1856. It was twice extended; first in 1874, and the work carried out in 1900 more than doubled the size of the house. The Riccarton estate has in stages become the property of Christchurch City Council and Riccarton House itself was sold by the Deans family to the city in 1947. Damaged by the earthquakes in 2010 and 2011, the repaired and renovated building was reopened in June 2014. Riccarton House is used as a restaurant and for functions, and a popular market is held on Saturdays in front of it.
