From the Maitland Mercury report:
The building of a multi-million dollar wedding chapel and conference facility with a link to the Hunter Valley’s convict past is underway. Known as The Carriage House, the chapel and conference centre is at The Vintage in Pokolbin. One of the main recycled building materials used in the project is sandstone dating back to the 1830s. The sandstone was originally quarried by convicts for a home at Jerry’s Plains. The hsitoric home has been demolished, with the discarded sandstone later found at Sawyer's Gully. The sandstone still bears its original convict markings.
