Mochi Home does a Euro bachelor pad 4 ways with just paint and a few accessories. The best thing about the computer-generated makeovers is that the original furniture remains the same. Very cost effective! It's also a great argument for choosing 'neutral' when buying expensive upholstered pieces. The top image shows what the room really looks like; below are its virtual makeovers.
Here we have the addition of wallpaper as well as paint.
