Opinions needed on indoor putting green please! Should I drill hole in subfloor?

[yellolab]

Hi everyone, thanks in advance. Building a new house, and putting green will be on second floor. Options are:
1) Just buy a putting mat like Big Murph, throw it down. Boring.
2) Build a platform using layed down 2x4 with plywood or OSB on top. Cut down cups to fit in the height, about 2.5" or so right?
) Drill a 4" diamter hole in the subfloor. Add turf and cup.(so cup would be between first floor ceiling and second floor floor), Or see next one....
4) Concerned about the hole(strenth) with above option, add another layer of subfloor for more strength, then lay down turf and drill cup holes.

What do you'all think?

THANKS!

I like option 5, cut a hole straight through floor so when you sink a putt the ball goes right down to the floor below and has a chance to take someone out

they sell 2 or 2.5 inch cups I think so you could just measure out the plywood and turf to cut right through and drop the cup right in. I just dropped down some plywood today. 3/4 inch but I bought cups that just slide inside the turf that are 1/2 inch x4.5... I don't get the ball dropping inside a cup but I didn't want to have layers and layers of stuff on the floor just so I could putt into a cup.

Jwheels9876 , yeah I see those now, from Birdieball. Interesting option. I would not have to cut the subflloor. What did you use for turf? I can't use the Birdieball turf, my dogs nails would DESTROY it.

[Jwheels9876]

I bought the starpro green material from home depot. I have a 12x8 green. I'll post a pic tomorrow, I'm in the middle of adding a rough looking border to it and cutting a 1x2 into plywood later

Get the power tools out. Drill baby drill!

Yah not sure my balls are big enough to start drilling holes in the subfloor. I really really want to tho, just need some to tell me their will be no structural issues....

[keither5150]

Your concrete pad in the basement is not structural. Drill a hole, then fill the bottom 1 inch with a concrete pre mix.... This should give you about 3 inches before your flooring....dricore etc. The concrete pad is designed to hold your carpet up. If there is a telepost nearby, you will have to make sure that you are about 4 feet away from the post to ensure that you don't drill into a footing.

There won't be structural issues; it's the same thing as having an outlet in the floor like many houses have.

Jwheels9876 Did you pick up the StarPro turf from HD or was it delivered? If delivered, did they deliver to your front door or some other freight option?

IMO, this depends on how big of a putting green you are making.

If you are doing the entire room then cut into the sub floor.

If you are just doing something like a 10x3 green, then build a platform. This is what I did. I built a 12x4 platform and dropped some Starpro over it. Full sized cups were easy.

2 and 3 are pretty easy do it all the time.

Make platform at 68mm the top with turf.
Timber edge, insulation board then interlocking floor boards or ply.
Trim cup down to fit, approx a 3rd off the bottom

There's always somebody who takes the contrarian approach. That's me.

I've never seen the value of building an indoor putting area. It's in essence flat, which real greens rarely are. Second, once you learn the breaks, well OK your repeating the same putts over and over.

I put three putting cups in my home sim. I think I've putted using them 5 times in 3 years....

Just me. I wonder if anyone else out there will fess up to installing a putting area but in reality, never using it?

[wbond]

I will fess up. I made a putting platform, just for straight putts that was 8' long. Rarely ever use it. However, i have used the exputt a lot, 50 putts from 6' and 50 from 10'

The complete opposite is true for me. I built an indoor 12x4 putting green with 3 holes. 1 hole down the center on one side, 2 holes split wide on the other side.

Being indoor (and in my home office) makes it very convenient to use it all the time. I can use it at night, when it rains, or whenever I want. Some days, 5-10 putts. Other days 100 putts.

I also wanted it completely flat with no breaks. I spent an hour or so with shims making sure it was absolutely level.

Being a great putter is highly dependent on having a consistent and repeatable stroke. If you can make those straight 5-8 foot putts 70% of the time like the pros do, making breaking putts is easy if you can read a green.

I would second that!

OP here..

I've decided tthis: Before they lay the floor down, I am adding another layer of 3/4 subfloor material to the existing floor to the putting area, so I will have a "platform" in my room that is 3/4 higher than the rest of the floor, so the new subfloor will be 1/5"(3/4" exisitng plus 3/4 new) thick in this area(which will be 8'x12' BTW) so I can drill holes worryfree, and have full size cups.

Ordered the Camry carpet for the putting surface.

WIsh me luck!
