My house is end terrace and next door's front garden shares a fence with our back boundary. I don't know who the fence belongs to. Next door has been a state for years but they've started smartening it up a bit recently and have made their front garden into a drive (ignoring the fact they don't have a dropped kerb but never mind). All fine except they've now built a whopping great bin store up against the shared boundary which is essentially a massive, stable, platform for would-be-burglars to climb up onto and hop into our garden!
Given my previous house not far from here was end terrace and we were burgled using exactly this route in - standing on bins to get over the fence, and then obviously in through a door - I'm feeling extremely stressed about this. DP - who is normally a massive curtain twitching complaint lodger (whereas I'm normally live and let live) is being infuriatingly calm about it and says there's nothing we can do and that I'm being ridiculous.
Technically it's an illegal construction unless they have planning permission (no way they do given they made a driveway without a dropped kerb) as it's in the front garden, so I could complain to the council. Would that be unreasonable? So as not to drip feed, they have form for this themselves as they previously complained to the council about DP making excessive DIY noise in the garden which upset him so much he's barely picked up a tool since. If they'd just come and knocked on the door he'd have packed it in happily.
I could go and knock on their door but I can't see them taking it down as it won't have been cheap to build and then if I complain to the council they'll know it was me (yes, they probably will anyway but still). What can I do so I don't fall out with the neighbours but also so I can sleep at night??
