Use light colours
Light colours can make the room appear bigger. Using a light colour makes space feel open and airy.
Give way to hidden storage
Multi-functional furniture pieces can come handy here. Consider installing sofa that turns into a bed, trunks and blanket boxes, benches and stool with storage, and foldable furniture.
Lighting is key
Natural lighting proves to be a key element in opening up space. Use sheer curtains for windows and doors to let the natural light come in.
Use mirrors
Mirror frames create the illusion of more space. A trick here is to place the mirror frame across the window to give the space of a more open feel.
Cut the clutter
Adding too many decorative pieces clutter space. Instead, limit the decor items to a grouping of 3 or 5. This is one of the important tips to maintain a sense of spaciousness.
