You can visualize your home office corner before DIY by using online room planning tools or apps that let you upload photos and experiment with furniture layouts, paint colors, and lighting options virtually. For example, try tools like ReimagineHome to test an L-shaped desk against two paint colors, add task lamps, and compare daylight versus evening lighting. This approach prevents costly mistakes by previewing changes, ensuring your corner feels right before drilling holes or purchasing materials. Visualization saves time and makes small-space office projects successful from the start.
