The planned Crossrail project – the largest addition to London’s public transportation system since World War II – is poised to lift the value of residential properties within a 10-minute walk of new Crossrail stations by an average 9% above normal home price growth in London by 2018, according to new research.

In a report published on Friday, property consultancy Knight Frank estimates the Crossrail effect will add an extra 1.2% a year to the price of houses near Crossrail stations in central London, resulting in a cumulative 9% rise by 2018.
