Homeowners considering buying a conservatory or pool house may be interested in a new prediction from the National Housing Federation (NHF).
The body believes house prices will see a number of "substantial falls" over the next year and a half.
It suggests this will lead on to a period of rises that will see average property values in England increase to £227,800 by 2014, representing a 20 per cent increase on current figures.
Despite this, homeowners should not expect good news any time soon, with the organisation suggesting 2009 will see a 12.2 per cent fall, while 2010 will bring a 4.6 per cent drop in value.
The NHF believes 2001 will see annual growth of approximately 1.1 per cent, which will rise to 7.5 per cent and 8.4 per cent in the next two years.
Finally, it predicts 2014 will see prices go up 6.8 per cent, leaving them £38,000 higher than the projected value of £189,800 for the end of 2009.
The industry body currently represents around 1,200 independent non-profit housing associations around the UK.
