At the ceremony, Revd Henry spoke about the mustard seed from Matthew 13:31 where it, being one of the smallest of seeds, grows to become a tree so large that the birds of the air come and nest in its branches. In a similar way, he hopes that Cedaroe Mansion, when completed, will become a sanctuary for residents to settle in and call home.

The ceremony closed with a shared meal at The Naturalist, where conversations continued around the hopes and vision for Cedaroe Mansion a future home rooted in community, nature, and thoughtful design.
