I have a sufficiently large garden.

Am I correct in thinking that I can build a large outbuilding (not as a self contained dwelling) with a max roof pitch height of 4m (with 2.5m at the eaves) but MUST remain 2m away from the boundary line? Otherwise I can build as close to the boundary line as I like as long as the max height does not exceed 2.5m?

You’re basically reciting the PD rules so yes, that’s more or less correct. Btw, the overall height of 4m is for a dual pitched/gable roof.

yes, to both of your questions. Just trying to pre-empt a difficult neighbour who will try to make life difficult.
How much is a certificate of lawful development these days?

If I was to put one of these in do I need to show the location where the outbuilding is going to be positioned in the garden or can I just put in the fact we want to build a 30 m² outbuilding somewhere on my plot and say we will be 2m away from the Boundry line with the maximum ridge line height of 4m and 2.5 m at the eaves?

£103.00 + the £25.00 Planning Portal service charge.

LDC applications need to be accompanied with drawings so the position and size of the outbuilding will need to be shown. The LPA would not be able to confirm the lawfulness without this information.

The 30sq.m is Building Regulations, so nothing to do with Planning.
That doesn't sound right. A Lawful Development Certificate for proposed development (as opposed to proposed change of use) merely restates the obvious legal position (and as such, is completely pointless except perhaps to appease the kinds of neighbours who can't be bothered to familiarise themselves with the legislation). I can't see that the Council's legal team are going to consider the position differently, if the exact size and location of development is defined or not - but I've never actually tested this.
