The historic "Belle Vue" home you mentioned in Hobart, built by Roland Loane in 1824, no longer stands. It was located on the block bounded by Davey Street, Molle Street, Fitzroy Place, and Ansell Street. Over time, the area has undergone significant changes, and the original building has been demolished. Unfortunately, the exact street number of "Belle Vue" is not well-documented due to the changes in the area's development over the years.
