1. Add a few low maintenance plants or nearly natural flowers to add some greenery. Even looping beautiful vines around your seating and tables will add something special. 
2. Include a libation and snack area in your patio retreat. Get creative using hot or cold drinks, charcuterie board and other finger foods. Having a dedicated space will reduce the number of times that you are in and out, interrupting your Zen moments.
3. Drape your seating with warm throws. Step-up your décor with inexpensive pillows and throws to add a bit of warmth as the evening cools down.
4. Add colorful string lights overhead, or along your fence line. String lights will set the mood; colorful twinkling lights will make your evening festive.
5. Incorporating a rug (or a few of different sizes) under foot will increase your comfort level and add a bit of luxury. A rug in your outdoor space adds permanence to your set-up. You will find yourself using the space more often.
6. Get a patio heater, large or small to up your comfort level. Including a heater on your patio will also allow you to enjoy the space in early mornings as you have your coffee or power up with a green smoothie.
