The front walls of two homes in Reepham Road, Hellesdon was destroyed in a single-vehicle accident early on Saturday.
A red Volkswagen Golf struck the wall after running off the road just before 6.48am.
A Norfolk Constabulary spokesman said the driver was unhurt.
He said: 'Basically a car lost control and went into the garden wall of a house. The driver was fine and did not require any hospital treatment.'
Fire crews from Sprowston and Earlham were called in to make the area safe.
