Minimalist decor, where less is more, is a perfect simple study room design idea. If you are an urban dweller with limited space in your apartment then this style is best for you without a shadow of doubt. In other words, simplify everything and avoid bulky furniture or excessive decor. Your desk can be a simple one with only a worktop and no drawers or storage compartments underneath. You walls can be white and plain for a clean look. White, as a colour scheme, is known to bring in soothing energy into a room – just what you need to focus!
