Thats an idea... what ever is necessary to have yourself up and running in the least amount of time, and have the equipment protected from the elements when not in use and in storage...
I opted for a small 1.8 x 2 meter area for my observatory, for the same reason as you, small back yard space.... but I have a movable cover, the half of the cover rolls off the scope to reveal the sky, rolling over the other half which is lower and houses the computer. Nice and compact but does the job... of course the difference is that I'm using a compound scope so it is not even close to the length of yours and the peak height of my movable hut is 2.2meters.
