Feeling a bit down? Maybe it’s time you redecorated your living room or finally tackled that remodeling project. No, seriously. In a recent Houzz survey, 87 percent of the more than 6,000 respondents said that their home design impacts their overall happiness. So if you’ve remodeled or redecorated your home in the past two years, you might be among the 74 percent who say they are now happier at home as a result. Of those who describe their home as being “in need of work,” only 51 percent reported feeling happy at home.
