Further to Scotty’s post – it’s all about residents using the Common Property for its intended use, and the foyer was not intended as a storage area!
It seems to me that many residents of Strata Plans are plain lazy and expect that anything outside their front doors is for them to use in any way that they choose, and that anything on that area that’s not theirs is the Owners Corporation’s problem.
Just look at the accumulation of junk mail in and around the letterboxes, and the boxes, mattresses and similar surplus items on the ground around the garbage area!
Anyway back to the pram in the foyer, the attitude of other residents will be “whats good for the goose is good for the gander” and the problem will soon become endemic. So I’d write to your fellow Executive Committee Members (including the goose) and politely suggest that leaving prams and bicycles in the foyer and inside the entrance doors is inconsistent with the intended use of that Common Property, and that Members should both set a good example and resolve to write to all residents to inform them that leaving prams, bicycles, and other private property on Common Property is not permitted.
