There are three main materials that are characteristic of an industrial style kitchen - exposed brick, wood and metal. These materials work together in balance to create a style that exudes practicality and unpretentiousness. The movement initially begun as a work place environment as companies took over raw, industrial spaces, but that transitioned into a style for loft homes, and ultimately expanding into a design movement used in homes and luxury contemporary apartment spaces.
Your other option, the filtered models, do not do as well because they will recycle the same air within your building only they run it through a charcoal filter first to make it cleaner. While a ducted model is preferred in most situations, they can be a bit more on the expensive side. Not to mention, you may not have the space necessary to fit the ducts. It is important that you find industrial extractor fans that have been built to last.
The worktop may also include a large built-in hardwood chopping board, with a pull-out waste-disposal drawer beneath into which to scoop vegetable peelings, and perhaps a slab of cool, smooth marble as well, traditionally the best surface for rolling pastry. Otherwise a freestanding central work station with all-round access may include both cooking rings and a sink for washing fruit and vegetables. The height of all these worktops needs to be carefully calculated because at the wrong height they will make preparing and cooking food unnecessarily tiring.
The flooring of an industrial space is typically a sleek cement or dark or painted hardwood. These floorings are inexpensive and durable, and even when scuffed or marked up, they still look good in an industrial space. Lighting should be limited to simple factory type lighting and elaborate pendant lighting and chandeliers contrast with the overall feel. Yes, the industrial look is such a departure from traditional design, but it is still a look that many people love. It has a "simple life" type of feel, a carefree and easy breezy feel while still being raw and edgy. Your Kitchen will have a lot of character with this style.
