Not that I have seen.
You mostly cannot cross from one building unit to the next. Mostly, there will be communal walls. If one unit has a patio or garden, they will not to bear the (often quite high) financial burden for maintenance for others. Besides, "green spaces" are rare and frequented downtown, so having neighboring communities access your "greenfields" makes them crowded. Usually, building units will (historically) have either communal walls or the garden will be walled off.
