Unfortunately, most Shiro plots are clumped together with tiny alleyways to feel more 'Asian' inspired. It sucks that this person has no heart to think but a person is allowed to decorate their plot how they want. I hope they are inactive and the issue dissolves itself but you never know they could be night owls and on when you sleep. I think look for another plot, maybe hope for one in your ward so you can stay near your fave neighbours.

Or even though it sucks, teleporting into the estate isn't a major 'yay' and need to see. Screenshots can be taken in other places of your plot if need be and /gpose is the best tool.
