Planning for front deck OBS with outhouse type roll off cover.

I am thinking a pier 6 feet out from the existing deck corner and adding a 16'X16' deck at the same level as the existing deck and the warmroom is in the house.
16X16 should give me the ability to expand.
When the concrete is poured I will have an extra place to mount a second pier and would just need to pull up some decking to access the second pier area that wuld be a steel bolt down where the primary concrete pier will come up through the deck at about 4 to 5 feet.
I have been testing all of the connections, so far so good with USB telescope and camera control from the house.

The pier is going to be 6 feet off the existing corner of the deck, in a few pictures you can see a red circle.

Temporary!!! Checking for placement of OBS
The wireless camera on the tripod in the background allows me to hear and see the telescope operate at night from inside.
