I think you'd need a little more than that. I have a 12x16x10 and I think it would be REALLY small even with two more feet.I can't make up my mind on what I want to do for mine. I have a cage set up in my backyard and then a net set up in my garage that I've been using during the colder months. The garage set up has be somewhat mobile so I can set it up and take it down for car access. And the garage height is a little under 9 foot which is not ideal. The outdoor space has more air flow for the hot Oklahoma summer months.
In an ideal world I would build like a 14x16 foot shed with 10 foot ceilings. After looking at our HOA though I don't think this is doable in my back yard.
Mostly i just use the range function working on my swing on it vs trying to use it for sim golf with TGC. I was looking at setting up some kind of retractable screen in my garage that would be easier to set up/take down, that I could also use a projector with. I just use an iPad to either use skytrak range or use remote streaming for TGC on a PC I have inside currently.
