If you want to go for the natural look when it comes to your kitchen design, one way is to use organic and sustainable components. Good choices for kitchen worktops include natural stones, such as marble and granite, which are known for both their aesthetic appeal and their low maintenance benefits. Slate or rocks are great for wall covering. Rocks have good thermal mass and offer insulation, which makes them perfect for properties in colder climates. Other sustainable materials to choose from include reclaimed wood, cordwood and bamboo. Most of these materials come in wide variety of patterns or colours, making them a versatile choice. For example, quartz is available in a large variety of styles and shades.
