A Question about Front Focus and Hyperfocal Distance

I just don't understand the use of the hyperfocal distance in this issue. Even if you know that hyperfocal distance you must be able to set focus to that distance. I don't know how one can set focus to a distance of 19m. Most lenses have an distance info scale but that's quite rough.
And what about when that house is just in front of several trees or another subject?

This is the easy part, if you have the distance measured correctly.

Set the camera to single point focus and focus on something that is 19m away using autofocus. Keep the shutter release pressed half-way down (or use back-button focus), re-frame the shot and press the shutter release all the way to take the picture. This is probably more accurate than using the distance scale on the lens (only a couple of my lenses have the distance markings on the lens barrel).

The only problem with the method is that by pressing the shutter release button half way down, the default setting on most cameras locks in both the focus and the exposure. Using manual exposure fixes this issue, if the lighting is different on the target spot versus the subject.

Or use back-button focus, with the back button set to focus only.

Thanks, gents. As to focusing, I'm always in manual and have no back-button. I did like the back-button on one DSLR I had, but I went retro, so it's long gone.

I'll probably take the DP2 Merrill (30mm, 1.5 crop) which has quite a good 10x focus-by-wire, and the DMC-GH1/(14-45mm, 2 crop) which also has the same.

Maybe an elevator too, since the house is actually on a hill.
