With the proper lighting, every room can be showcased. Having curtains that draw completely past the window frame exposes the room to lots of natural light. Mirrors on the wall can reflect this light without taking up extra space and increase the visual appeal of the interior.
There are dozens of places around the home to stow away unused things and cleaning supplies alike. Hanging cleaning supplies like the broom and mop up on the closet wall will allow for bigger items to sit on the ground, like seasonal decorations in a box, or hidden gifts for the holiday season. In the kitchen, hanging a spice rack on the inside of a cabinet will allow room for the wine cabinet you've always wanted but never had room for!
Furniture - Less is More
A cluttered floor plan just screams for a stubbed toe. Why not simplify this by selecting a few pieces of furniture rather than several smaller items? Instead of a guest bedroom with a twin bed and full size chest of drawers, you could get a queen sized bed and throw an extra closet bar in the closet to maximize hanging potential.
Open up the Bathroom
The bathroom is a great place to add a sense of open space. Instead of a clouded glass door for the shower, swap in a curved curtain. This will give off the impression that the bathroom is much bigger than it actually is. Additionally, add some floating shelves behind the toilet for towels and other bathroom accessories to clear up some counter space.
