Simple. See this room:
I think you can make any room give a big impression by sticking with one colour and painting it that. White obviously looks great, but any neutral colour would also work. You could also pick a more vibrant colour, but then it gets trickier.
Most of the things in this room are low cost: shelves, stools, rug, fridge. The overall impression is greater because it is all white.
