Hello everyone, I hope you guys here can offer me some advice and experience on my situation, I've furiously been googling this for a few days, read alot of stuff, some conflicting, and found this forum. Anyway I thought I would make my own post given it appears almost all situations are unique and there's alot of interpretation involved.
In 2017 I built what could be considered a home bar/garden room, what ever you want to call it, I was aware of permitted development, but probably didn't do enough to fully understand it and the do's and don'ts in my situation, details on my build are below:
Height is within rules, under 2.5m from the highest point of my property
It is within 1m of my boundary on both sides
Under 50% of my land
I live on an end house, so it's within 1m to the footpath on one side.
22m2 internal area, 3m2 overhang of the roof/decking area infront of my bifold doors.
Timber framed on a concrete base.
Kingspan insulation, walls, ceiling and floor
Fireboarded plasterboard walls and ceiling - then skimmed
External cladded walls
GRP Roof - Flat roof
Toiler/sink with waste pipe going direct to the manhole/drain in my garden
Electric with it's own breaker board - signed off by an electrician.
It's a good build, done my by father (joiner of 40 years) and myself. I believe I fall foul of quite a few PD rules here.
I'm looking to sell my house very soon and not concerned my build could cause me issues, so I'd like to apply for a lawful development certificate under the 4 year rule.
Can any of you offer any advice at all, can I apply myself, does it need to be really in depth and water tight given it's over 4 years.
Edit: In terms of proving when it was built, I have google earth/maps/street view - dated
Pictures from phones etc. which I assume have metadata
Invoices for materials - dated
