For some time, Monro leased Warwick House, at the time known as "Sunnyside". The house was built for Arthur Fell (father of Charles Fell) in 1854 by builder David Goodall. When Fell returned to England, Monro leased the house. Later, the house was bought by Nathaniel Edwards. The building at 64 Brougham Street in Nelson is one of the finest and largest examples of early Victorian Gothic Revivalism still remaining in New Zealand. At one time, the house had about 50 rooms. The building was registered on 25 November 1982 as Category II with Heritage New Zealand, with registration number 1618.
