South-facing gardens add less than £800 to the value of a home, according to new research.
A study shattered the myth of south-facing property attracting a big premium by saying they are worthy a mere 0.37 per cent more than other homes.
It means that on the average UK property price of £212,000, the south-facing boost is just £784.
The research by insurance firm Direct Line said that estate agents and property experts have regularly highlighted the benefits of a south-facing garden.
They were thought to be more desirable because they typically are in sunshine for most of the day, making them warmer and brighter.
But an analysis of property for sale shows this is not reflected in prices.
It shows that those with south-facing gardens carry a premium of just 0.37 per cent over those with north-facing plots.
"The research highlights that south-facing premiums may well be a myth, but a room with a view comes with a hefty price tag."

However, homes with river views do come with a bigger bill, averaging nine per cent more than similar properties without this sought-after outlook.
It could mean homes over looking a stretch of water costing on average £19,000 more than identical properties without a river view.
In one new north London development, a three bedroom property with a river view has an asking price of £850,000 – 42 per cent more than an identically proportioned and designed property elsewhere in the development that costs £600,000.
The research also reveals that going up in the world could cost home buyers considerably more.
Property developers are demanding big premiums for flats which are on higher floors.
One developer admitted adding a £15,000 premium to the asking price for every floor, bringing new meaning to the phrase 'sky high' prices.
An apartment on the 14th floor of a new development in Islington, north London, on on sale for £850,000, 30 per cent more expensive than an identical property on the third floor.
In another new London development a one bedroom flat on the fourth floor costs £438,950 while an identical property on the eighth floor is on the market for £475,0003.
Katie Lomas, of Direct Line, said: "The research highlights that south-facing premiums may well be a myth, but a room with a view comes with a hefty price tag.
"People are prepared to pay thousands more for the same amenities and layout because a property is located higher in a building, has a more scenic vista, or because it overlooks water.
"However, while picturesque river views are much admired it is worth noting properties built near water may cost more to insure because of increased flood risk. Purchasers should check the likely cost of insurance before they commit to buy."
