This is my first obsy build and works fine for my needs, it’s a 5’ square converted shed, and holds my EQ8 mount and side by side dual Tak set up, with RPI running Stellarmate for full image capture and mount control.
Not at all as the pier height takes the scope high enough to clear the walls, besides the surrounding houses block out the sky before the shed walls, and it’s 5 foot square more than enough room for my Tak FSQ85 to move around...I agree it does look a bit smaller on the video that it actually is....??
