I do a lot of Handyman and remodel work, many of my clients get ideas from the popular real estate shows. Because of this I end up painting most rooms grey because that is the in color and goes with anything and dealing with a few other trends. Some trends do not work in every situation though.
Barn Doors - These can make a room look classy, and in some situations really do add to the look of a remodel without adding to much cost over a traditional door. There are some exceptions though so I made a video showing why that is the case. This client insisted on having them but they were not the best option that is for sure.
