Latest housing market reports show that construction activity fell at its sharpest pace in at least 11 years in June, according to a survey released on Wednesday.

This was one of the clearest signs yet of how falling house prices are hitting the wider economy.

The news coincided with a plunge in homebuilders' shares after Taylor Wimpey, the sector leader, said it failed to raise the extra capital it said it would just two days ago when it warned of a "significant downturn" in the housing market.

According to Reuters, the construction sector's travails brought on by plunging real estate values were glaringly apparent in the Chartered Institute of Purchasing and Supply's construction PMI which fell for the fourth straight month to 38.8 from 43.9 in May.

That was the weakest reading since the survey began in 1997. The housing sub-index was also the lowest ever, falling to 25.6 in June from 32.7. Any reading below 50 signifies contraction.

Howard Archer, economist at Global Insight: “The construction sector looks to be in for an extended, very difficult time. This adds to the serious problems currently facing the UK economy.”

Falling house prices also meant consumers were able to take out much less equity from their homes in the first quarter, Bank of England figures showed, removing an important prop for consumer spending.

Until recently, rising house prices have encouraged Britons to refinance home loans to free up cash for other spending. But that trend appears to have turned.
