Home owners who failed to pay fines for breaching planning rules could face court after Midlothian Council referred them to the Crown Office.
Councillors this week approved plans to seek prosecution against two separate homes where they issued enforcement notices which have not been met.
One of the cases involves couple James Bevis and his partner Louise who built a sunroom and garage at the side of their corner house in Mayfield five years ago for just £3,000.
