If you have the space, make a cozy cabana to put in your back yard. First build the frame using PVC pipes. Then dig the foundation holes. Add the legs and, at the end, add the curtains. You can customize this project however you want.
This simple and ingenious outdoor room (also designed by Whiteley) uses a frame of pvc pipe set into pvc sleeves pounded into the ground to define a sitting area. The curtain fabric is weather-resistant Sunbrella fabric.
