Natural materials serve as the foundation of Spanish modern interior design, bringing an earthy, authentic feel to the space. Follow the same path and utilize resources that have been part of Spanish architecture for centuries. When starting your Spanish modern transformation, incorporate elements like exposed wooden beams, stone countertops, and terracotta tiles to bridge the gap between traditional charm and modern elegance. That way, you will add texture and depth but also introduce a sense of history and craftsmanship.
