Tunnel House

In spring of 2005, artists Dan Havel and Dean Ruck set out to "sculpturally alter" two houses in Houston's Montrose neighborhood. In the temporary project, called Inversion, they created "a large funnel-like vortex beginning." Their press release at the time described the project; both houses, already scheduled for demolition, were ultimately destroyed:

The exterior skin of the houses will be peeled off and used to create the narrowing spiral as it progresses eastward through the small central hallway connecting the two buildings and exiting through a small hole into an adjacent courtyard.
