Kitchen owners are choosing to create separate work zones to cater for their specialist food and drink interests, an expert has said. Writing for Freep.com, Neil Wertheimer, editor-in-chief of Fresh Home magazine, said this does not require a major kitchen makeover as work zones could be created out of existing counter space. This could include making new use of a kitchen sink area.Most cooks have a specialty, but rarely in the past did we create kitchens to accommodate it. The trend now is to add coffee bars, wine storage and tasting nooks, pizza-making stations or even baking centers based on personal interests, said Mr Wertheimer. In considering other cost-saving kitchen changes, Mr Wertheimer said that the use of salvaged materials is a good option given that the supply of available old materials is endless. He added that instead of hiring a salvage company to help retrofit a kitchen, homeowners could simply head to a market in search of vintage furniture or utensils.Bruce Curtis, owner of the home remodelling firm Washtenaw Woodwrights, recently wrote for AnnArbor.com that the wide range of eco-friendly materials now available means that homeowners should make careful selections when deciding to go green.
