Modern with a rustic touch
White paint is extremely versatile, and is a perfect wall color for a large living space with a dark or vibrant color wood floor. To create more drama it's worth to use the same type of wood on some of the walls. Great idea, keep in mind while creating modern open spaces.
Concrete is also a modern way to accent your space such as this concrete countertop flowing into a bench and around to the stairs, nice touch. To add a curve to the modern look of your space, try adding some rustic furnishings to make your space pop.
