Avoid using heavy furniture such as big stuff sofas, wardrobes or bookshelves that have closed shutters. Instead if you use sofas with sleek frame (like the one in bamboo furniture) this will create more transparency and will help in perception 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. Within an interior space that is empty the thought of "small or big" is often decided depending upon the dimensions of the space. The amount of the space based on the boundaries of ceiling, floor and walls defines the space. The openings in the walls further help in reducing the bulkiness of the space.
