Human remains have been found at a work site in a suburban front yard at a home in West Hobart.

Excavation workers made the grisly discovery late yesterday afternoon while working on the foundations of a home in Hill Street.

Police said the incident was not suspicious, because the site was once a cemetery for the Wesley Uniting Church, with the last burial in 1872.

The identity of the deceased person is unknown.

Workers said they were adjusting the home's foundation piers when they came across a skull.

The remains were about 1.5 metres below the ground, and about 60 centimetres below the foundation of the home.
