Playing with proportions is a sure way to make a space feel uniquely your own. A tweak here and there can reap dramatic results, especially when applied to areas that usually come in standard dimensions, such as the depth of a worktop. Super-sized slabs of stone or marble are the obvious choice for ushering in a luxe feel, but terrazzo or concrete would provide similar wow factor. Wood offers a less costly way to get the same monolithic effect, whether you go rustic and reclaimed or sleek and contemporary. Alternatively, combine materials for an extra custom twist.
