Two walls prepared for the ROR observatory

Have a ‘shorter’ 4-ft lower side wall which is for south (will be along fence line) and taller 6-ft west wall done now (west is towards stack of lumber). The upper 2-ft of south wall will be attached (roll) with roof (moves to west). Chesapeake Bay view in background is East. Thinking about including a drop-down upper panel on East adjacent to the entrance door (which will be in NE corner - convenient for me as this is closest point along my flagstones from back porch). Mostly will be sitting inside house (staying warm) at laptop (operating remotely) for imaging sessions versus spending nights doing visual at eyepiece.
