A Reuters poll has shown that house prices could fall another 11% this year.
The survey of analysts at UK banks also suggests there will be a further decline of about 3% in 2010. This would equate to a 30% drop in prices from the 2007 peak.
Several thought the decline could even reach 40%.
The poll follows a Construction Products Association (CPA) survey predicting a 32.9% drop in private housing starts in 2009. The CPA says overall construction output is set to fall by nearly 9% this year and a further 4% in 2010.
