This season At Home Putting Greens installed a number of custom indoor driving ranges.  Most of these have been in residential basements and garages.  The nets are 10×10x10 and on a tracking system.  That way, when you want more room, simply pull back the net.  Our tee-line turf actually holds a tee.  You can tee up with a short or long tee just like at your local course or country club but in the comfort of your own home.
