Kitchen trends will come and go, but some things never go out of style. If you want a kitchen that will stand the test of time and still look as beautiful twenty years from now as it does today, consider incorporating one of these seven elements.

Just for fun, here's a gallery of 1920s kitchens. Even though these kitchens are nearly 100 years old, you'll spot some of the same features in the modern kitchens below — proof that these elements are truly timeless. (You can visit Antique Home Style for even more kitchens from this era.)

2. Interesting neutrals.
Sticking to relatively subdued colors will help your kitchen weather the tests of time, but this doesn't mean it has to be boring, or that white is your only option. Try a light grey, or even a light, unsaturated green or navy.

5. Glass door cabinets.
This is a great way to visually open up your kitchen. If you have some dishes that you'd like to keep hidden, try a mix of glass doored and traditional cabinets.

Or beadboard all over.
