Besides the obvious benefit of separate closets giving separation between a messy person and a clean person, there is one little used benefit:
Separate closets provide an opportunity for you to customize and design your storage space to reflect your personal style and taste. From selecting the materials, finishes, and hardware to incorporating decorative elements like mirrors and lighting, you have the freedom to create a closet that complements your bedroom’s overall aesthetic.
This means that if one person likes to have a bright and airy closet, they can use white cabinets, lots of lighting, and glass front doors; and if the other person wants a closet worthy of James Bond, it can be dressed up with rich wood colours and moody, dark-painted ceilings.
Which one would you choose?
