The key to a healthy kitchen design is clearing out any clutter and ensuring the space is well ventilated, according to one expert.Writing for the Deccan Herald, interior designer Neera Gulati also said that lighting should be a priority in the kitchen, suggesting that white or pale yellow walls are good for reflecting natural light and giving a sense of spaciousness.These light wall shades can be complemented by natural materials such as wicker baskets, cotton and plants to help create a relaxing environment. You should ensure that everything works in your kitchen from light bulbs to food mixers, as broken gadgets sap your energy levels, she added.Two homeowners who are bringing natural materials into their kitchen design are Lori and Jerry Bork who recently told the Daily Republic that they had used wood from an old tree which had been in their garden to make new kitchen cabinets.
