Creating open space
One of the major issues in interior decorating of single-living apartments is space or lack thereof. This problem can be solved by a few tricks of mere illusion.
Forget over-stuffed sofa and chairs and try to go for furniture with simple and clean lines. Use tables with clear glass for extra surface space while de-emphasizing clutter. You can also arrange existing furniture so that they don’t block views to doors and windows. Doing so would minimize the feel of smallness.
A warm clutter-free wall can also give an illusion of more space. Paint a single wall with a warm solid color such as berry and wine. Put up one or two striking well-proportioned wall pieces instead of small art pieces that can only clutter your wall.
You can also use plants as the focus of your room. You can use tall narrow plants like bamboos stems anchored by rocks in a large terracotta pot.
