I've redesigned my kitchen three times in the last decade, and the farmhouse sink and subway tile trend is starting to feel like the wallpaper of our era — everywhere and already dated. The real question is whether following design trends at all helps create better living spaces or just feeds a cycle of waste and regret. My neighbor spent $30k on a remodel that'll be out of style in five years. Is it better to stick to timeless principles or embrace what's current?
