In Q3, investment in home improvements was $178 billion, while construction spending on new single family (SF) houses and townhouses was $172 billion, each about one percent of GDP. Similarly, in Q1 spending on home improvements was $161 billion, slightly above the $157 billion spent building new SF structures. Normally new SF construction spending is double spending on improvements! Worse, to date in 2013, new SF construction spending is flat.
