Concrete floor? Paint it! Concrete is easy to paint. This pattern looks simple. Tape it off and start rolling! Just be sure to choose subdued colors so as not to make the floor the main attraction. If it becomes the main attraction, all of your painting flaws will be center stage.
The bright colors work in this photo because every thing else in the space is white and subdued. The only color comes from the green painted, glass doors, the large plants in the corner, the pillows, and the furniture. I love using fabric curtain panels outdoors. An inexpensive alternative to custom , outdoor panels is to buy ready made, white panels from Pottery Barn. I washed mine before installing them because they shrink when washed. Now when they get dingy, mildew-y, or dirty I can throw them in the wash with a little bleach and they come out like new.

All of these outdoor rooms have something in common, they are INVITING! They make you want to go outside and enjoy the fresh air instead of plopping in front of the television. Make your outdoor space a place for YOU to enjoy, don't save it just for entertaining. Have breakfast out there, sort the mail out there, talk on the phone out there, do WHATEVER out there, just get out there and enjoy!
