Americans’ spending on home improvement will increase in the next few months more strongly than it has done since the boom that preceded the crisis. Then from the middle of 2014 this growth (measured against the relevant periods of the previous year) will no longer be quite so strong. This forecast comes from the Joint Center for Housing Studies of Harvard based on the leading indicator of remodelling activity (Lira). The indicator shows an increase of 10.4 per cent for the third quarter of 2013, while in the first quarter of 2014 consumers will spend as much as 17 per cent more on improvements to their own four walls than one year previously.
