There may be other names, the one I am familar with is **Porte cochere**

By way of further confirmation, here is the listing for the [pictured property, Ivy Road House, Atlanta][2] on the designer's website.

> This distinctive painted brick Atlanta Residence was built to maximize its narrow lot by organizing the site with a circular drive that leads to a formal front entry and a porte-cochere that leads to a more informal side entrance.
