The front of the structure remains as Strickland built it, but the rear and interior have been greatly altered. In 1898, the architect James Windrim renovated it for the bank, replacing Strickland's vault and directors room (as well as a small office added later) with a much larger two story structure of fireproof brick and iron construction, while the church divided the main room into two stories and added additional office space at the rear in 1930 and later tenants made further changes.
