Garage question

[Howitzer]

I just want to be sure I have this correct before I start researching wooden garages.

The current garage is 3.5 X 6 metres. It needs knocking down as the floor has cracked and there is a large gap at the top of the rear wall, essentially it's partway through falling down.

As one wall is right next to my boundary I know I can't have a ridge height greater than 2.5 metres, but as there is space behind the garage I can extend it to the back fence, another 2 metres or thereabouts.

So aslong as the ridge height is 2.5M or under I can make the garage as big as I want aslong as it does not cover 50% of the original garden area?

Dave!

I think you are correct, however, have a peruse here:

Needs to be at least 5m from main house also to be exempt from PP, also no part to be forward of the front of the house I think. Size after that may become an issue for building regs rather than planning - upto 15m2 they don't care, 15-30m2 needs to be non combustable material or if timber then at least 1m from the boundary (could be an issue for you) - over 30m2 and building regs required regardless.

Least I think that is the case, had a peak around recently and put up a 27m2 timber without needing to do or notify anyway... least I hope I was right.
