Interest in both self build and home improvement continues to grow, according to a recent survey from The National Homebuilding & Renovating Show. Twenty nine percent of visitors to the Show, held at the NEC in March, are currently involved in a self build project, compared to 20% in 2009, with 38% involved in a renovation project, compared to 34% in 2009. This homeowner confidence is mirrored by recent news from the Nationwide that house prices in the UK have risen by 10.5% in the year to the end of April.
