Planning for first enclosure

[JoeBlowGolfer]

I have an unfinished basement that will remain unfinished for at least the next two years. I'm looking to build an enclosure that really needs to be more functional than pretty at this stage to support a GC2. My space is 12'W x 14'D x 9'4"H. I want to maximize the screen size, and I've been told that I can't permanently cover the window on the right. When not in use for golf, it needs to continue to be a workout space. Here's what I'm currently thinking, would love to hear some feedback.

First, is 12' a wide enough space to hit from the center, or do you think I'll need to line up right of center just to be safe?

Flooring
I'll put down new foam tile workout mat (3/4") enough to cover 12'x12'. I'll continue to use my 5'x5' Quattro mat on top of the tile.


Frame and screen
I will use Carl's premium screen. Instead of building a typical enclosure with a top and sides, I'm planning to use a heavy weight fabric hung from a curtain track on the ceiling for side containment that I can open when not in use. That should keep the window free. To maximize the screen width, I plan to build the attached frame out of EMT and put pipe insulation on the vertical poles. The screen will wrap around the front poles and bungee to the back poles.

1. Do you think this setup will allow the the screen to give enough on impact, or might the screen not overcome the friction of sliding on the poles and be too stiff?
2. Do you think I would need cross poles in the back on both the top and bottom to keep the frame rigid enough, or will the EMT fittings be enough to keep the frame from twisting badly? I might secure the top pole to the bottom of the joist, which could help there.

Sides
I plan to use an 18oz fabric on a ceiling mounted curtain track for the sides. I will re-purpose some of the workout tiles to line the cinder blocks on the right side in case of errant shots. I'll attach the side curtains to the back vertical poles of the frame.

Ceiling
I'm going to use some of the same heavy fabric to cover the top portion of the screen to make it a true 16:10 aspect. I'll screw 1/2" plywood to the ceiling ( 3 x 4'x8' sheets) so my ceiling will be 12'x8'. I'll cover that with the foam workout mats currently on the floor. From the screen to about 4' out, I'll do 3 to 4 16" sagging loops of fabric to catch balls bouncing back from high off the screen, or potential high wedge shots.

Projector
Still researching the best fit for the space. Is mounting right above the ball typically out of harms way? I do have more than 14' of depth right now to mount the projector, but won't in the future after finishing the basement, so might as well not count on it now. I also don't want to go far enough back that I will cast a shadow.

Any feedback is welcomed. Going to try and throw this all together fairly quickly.

Are you hitting at the window or those mirrors?

I'll be hitting toward the wall with the TV and mirrors.

Exciting. Sounds like your planning is on point. I also wrapped my screen around foam insulated EMT using tarp clips an bungees. Works well.

That sounds promising. So you were able to get the screen tight enough so there weren't a lot of wrinkles, but still able to keep balls from flying back at you like a trampoline? Did you happen to take any pictures during your build?
