Geometric patterns are a really hot trend in interior design at present, one expert has said.Janet Eavenson, owner of Leonard Provence Interiors, argued that while the practice of using geometric shapes in home designs is set to grow in popularity, it may also be out of the price range for some homeowners.It is a little bit more challenging to find these items - these geometric items - that you can actually afford because usually it is just at the high-end, she said.When it starts trickling down, then it starts getting more mass produced to the low-end where everybody can afford it.Elsewhere, Ms Eavenson observed that grey appears to be getting more and more popular, with some people opting to paint entire rooms in the colour.The comments come after an article by Kitchen Design Centre suggested that a central island, potentially with its own kitchen sink, can help to make a room more functional and contemporary.
