Avoid using heavy furniture such as big stuff sofas, wardrobes or bookshelves that have closed shutters. Instead when you use sofas with sleek frame (like the one in bamboo furniture) this will create more transparency and will help in thought of more space. If kept open will reveal more wall surface behind them and reduce the "bulky" look, also storage units such as TV unit, book shelves. In a interior space that is empty the thought of "small or big" is normally decided depending upon the dimensions of the space. The amount of the space defined by the boundaries of floor, ceiling and walls defines the space. The openings in the walls further help in lowering the bulkiness of the space.
