I have similar problems moving my bike around in the shed, not to mention a narrow alley to reach the road.
I have a sheet of aluminium, around 60cm square, which I strategically place under the bike. With the bike on the centrestand, I can then swing the bike around whilst pushing down on the rear carrier. Alternately, I can set the bike on its sidestand, again on the sheet and edge the bike around. Either of these operations need care, but with practice, both methods can be useful. I perform the task of turning my bike around in a 10X12 foot shed, which has other items -a cabinet, tumble drier, racking, tool cabinet, inside.
My bike can be ridden in and out of the shed, with care.
