Hide your garbage can - One of the first projects that you can undertake is moving your kitchen garbage can to an out-of-sight place, like under your sink. This is a simple project that you can undertake yourself, and will help simplify your kitchen's look, on top of increasing your floor space. You can also take this as an opportunity to consider whether or not you'd like to try your hand at going green. Consider making a separate hidden bin under your sink for recycling.
Under-cabinet lighting - Under-cabinet lighting is an easy way to add some ambiance to your kitchen. You can install strip-lighting under your cabinets yourself, or hire a contractor to install a few. This will serve to highlight certain aspects of your kitchen, which can't really be done by relying solely on overhead lighting.
Tile backsplash - Installing tile in the area between your cabinets and cupboards will make cleanup nice and easy, while adding a bit more style to your kitchen.
Solid surface countertops - This is one of the big remodels, but it is also one of the most beneficial. If you live in a home with laminate countertops, then it may be time to consider upgrading to something a little more style-conscious and useful, like granite or marble.
