Memphis-based architecture firm archimania designed an extension to a historic governor’s mansion in Nashville, Tennessee, by creating an "unbuilding"- a sunken courtyard structure that adds extra without marring the landscape or existing architecture. Instead of building a new structure next to the existing residence, the architects decided to go underground, and the final result is an invisible addition that looks elegant and blends into the natural surroundings.

The sunken courtyard receives an abundance of natural light and is filled with greenery.
