Construction output in the West Midlands is expected grow above the national average to 2008, although a marked slowdown is expected compared to previous years.

Economic forecasting group Experian, said it expected a national growth rate of 13 per cent over the next two years.

The West Midlands, South-east, Greater London, East of England and Wales would see a higher than average performance, it said.

However, Experian maintained that the construction boom in the North of England had ended as investment in public sector infrastructure has largely stagnated.

"The decline in public investment will have a major impact on the North's overall economic prospects as construction has been the main contributor to the region's growth over the past five years," Experian said.

Wales and the South of England is expected to see the strongest construction growth.

Output in the South of England is exoected to continue to expand.
