A survey is being carried out on an old building in Saltash on Sunday before work can start on the re-creation of an Elizabethan garden at the site.
The garden at Mary Newman's Cottage in Culver Road is set to undergo a geophysical examination.
The Tamar Protection Society, which manages the cottage, has asked the Tamarside Archaeological Survey to see if anything is buried under the land.
It hopes to detect the old garden lay out, paving or any earlier building.
The Tamar Protection Society is currently looking for volunteers to help at Mary Newman's cottage in order to open the property on a more regular basis.
