According to property search engine Zoomf.com, the average price difference between a three and a four bedroom property in London is £161,221.

Zoomf claims the average price of a three bedroom property is £396,387 and a four-bedroom home at £557,608, many home owners will be forced to look at alternatives such as lift conversions and extensions rather than moving to a larger place.
Moving from a one bedroom flat to a two bedroom property will cost an additional average of £89,751. According to the search engine, currently there are only 5,698 one bedroom properties on the London market compared to 13,655 two-bedroom, 10,636 three-bedroom and 7,916 four-bedroom properties.

Mike Carter, co-founder of Zoomf, said: “The price gap between an average three bedroom and four bedroom property is so great that it is difficult to see how many people will be able to make the jump.

“What we will probably see is more and more people using the space they currently have to develop and extend their properties.”
