Do a Google search for Merry Go Round Observatories.

Yes Bill Volna's Set up is one of the best I've ever seen.
And heated too!!!!!!!!!!

I am talking about an alternative to both a roll-off roof and fixed buildings with domes on top; sort of an extension to the concept where the scope is still mounted on an equatorial mount, but the entire building rotates to put the slot in front of it. To think of it another way, the dome goes all the way to the ground, and I am imagining doesn't look very different from a small storage building. Unlike a roll off roof, it doesn't need an overhang area as big as the building. Unlike a dome, it doesn't stick up and say, "Hey! This is unusual. Maybe there is something to steal, here!"

But a total rotator observatory construction is described in reg spry's book make your own telescope .But using my own design.
I intend to construct one to house my 16 inch fork mounted newtonian .Easier to construct than a dome uses a full size walk in door and will have more wind protection than a roll off roof i don't need full sky access either as i am a visual obser of moon and planets .

I can see that if you were using a chain drive with geared motor of some sort,it might work.
Yet the central cog would have to be fairly substantial would it not and have a fairly large bearing for smooth operation.
It would be an interesting build yet I do not think easier than a Roll Off Roof OBS.

Wheels- I've found general purpose wheels which would be better for this than V-groove because you can use them on parallel tracks without overconstraining one: Garden raiway wheels:
The track bolts down flat for straight applications (like roll off roofs), so the need to learn welding is eliminated. It's aluminum so it won't rust or react with wood:
However, it can't be bent into as tight a radius as a small building would need, so it sounds like what is needed is 1/2" flat stock to bend in a circle with a three point jig.
The small building I am imagining would have a door which was also the lower shutter, with a sliding roof panel. The power for the building would come up through the circular non-moving center floor with the mount, and it would be controlled like a dome.

Sky & Telescope, Sept. 98
It's a round building with a walk through door/slot that rotates on a brick circle.
Looks straight forward as far as construction.
I can get a copy of the article if you can't fine it in a week or two, just let me know.

I've been interested in something square, with the idea being to make as much of it as possible in multiples of the standard stock dimensions for the raw materials. For example, walls in multiples of 4' so sheet materials could be used without trimming and the math would work out- something folks could build without a kit or lots of difficulty.
