Indoor Putting Green Design

Good morning,

I was not sure which forum topic to post this under, thought this would be best. I'm designing what I'm calling an indoor golf center. It will be 8ftx16ft with 8x12 putting surface and 8x4 hitting area. I'm going to building a platform on 2x4s topped with 4x8 sheets of 3/4 plywood.

The plan is to put down a base layer then the putting surface. The reason is so that it can accept chip shots a little better, as the hitting area is going to be removable and we will be able to chip to the green. The hitting area is going to have a "fairway" and "rough" areas to hit from. There is a lefty so I think I came up with a good solution we can all hit what ever shots we want. There will also be a net that will be like a batting cage lining the sides, top, and back to catch any shots made.

My question for you guys is how would you set up 3 cups and have slope on the green? I thought about having one end flat and putting a hole in the corner so we could do about a 7ft straight putt. I'm just not sure how to do the slope, I know I could just build it all flat and put a wedge under a corner to introduce slope.

Here is a picture of what I'm talking about. The black circles on the side is where poles will go for net. The hitting area is rough, fairway, rough.

Will your turf be permanently attached to the foundation?  If you can find a way to not make it attached, you could build/buy little wedges, semicircles, etc shapes and put them underneath the turf.  You could move them around whenever you wanted a 'new' green layout.

I'm thinking like pieces of foam board you could buy at a craft store, shaved down to whatever size you want to introduce slopes and grade.

Be sure to post pics when you're done!
