Sophia Gardens' progress towards becoming a Test venue has been given the seal of approval by the England and Wales Cricket Board.
Sophia Gardens is undergoing a £9.5m redevelopment
Bill Morris, an independent member of the ECB's management board, was in Cardiff on Friday to assess work.
The former trades union leader declared himself pleased with the rebuilding being carried out at Glamorgan's home.
"I have no reason but to give a very positive report to my board when we meet on 4th September," Morris said.
Sophia Gardens will host an Ashes Test match between England and Australia in 2009.
"All the requirements that we laid down for awarding the fixture is very much on schedule," Morris added.
"The project meets our expectation and out satisfaction."
The £9.5m redevelopment will see capacity increased from 5,500 to 15,643.
The Cardiff venue gained the Ashes honour ahead of the established Old Trafford and Durham's Riverside stadium.
