Your kitchen holds some of the keys to adding value to your home, an industry commentator has said.In a recent article, Adrian Sainz said that nicer and more expensive countertops [work surfaces], made from granite or quartz, for example could potentially add value to your home.Well-presented work surfaces can be emphasised with the choice of stylish, well-made sinks and taps such as those by manufacturers including Franke, Carron Phoenix and County.There are a range of undermount sinks which will fit seamlessly into a variety of work surfaces, such as with acrylic surfaces, laminates and more expensive, but more durable granite surfaces.It is also possible to add products such as waste disposal units and other accessories into a work surface-mounted structure, which will also add value to your kitchen.Increasingly homeowners are switching to work surfaces made from higher-end materials, with a recent study in the US showing that 75 per cent of new homes featured a laminate work surface as opposed to only 35 per cent in 2007.
