Don't forget planning permission and building control are totally different.... essentially the former is 'can you' the latter is 'how to'.

I've done a similar thing. Mine is a little larger than you are planning (7.2 x 10.8) but I made mine from 3.6m long sections so it's easily scalable.
All sections were made from lengths of 4" x 2" and clad on the outside with 150mm feather edge over a breathable membrane. I bolted the sections together then bolted the roof trusses on top where the sections join. I built it on top of a decent footing and two courses of brick just to get it up out of the ground and poured a concrete slab inside so my four poster had somewhere to stand (sadly I haven't got round to getting it yet!). Roofing is Onduline and the whole thing is insulated with 100mm rockwool and lined with 12mm ply.
I went 2.1m to the eaves and with a 1 in 4 pitch on the roof my ridge sits at about 3.5m so well inside the height limits for permitted development.
I did do a set of drawings and might share them with you if interested.

Is there a angle of pitch that is preferred for a dual pitch roof?

There are minimums recomended for different roofing materials, with slate for example the lower the pitch, the greater the overlap you need, therefore more weight, onduline has minimums too. Also if using trusses the closer to flat you get the truss design increases.
Id work back wards from the height restriction for permitted development. Mine as an example is 22 degrees.
Steel framed buildings go down to 15 degrees ish

Reading up if the shed is 2.5M hight or less I can have it 1m from the boundary if it is higher than 2.5m then it needs to be 2m from the boundary. So 2.5M high it will have to be

Just don't go flat. It will leak! maybe not today, maybe not tomorrow, but one day, it will leak
1 in 4 is about 17 degrees which I find both effective and aesthetically pleasing.

Ok, so if you assume 3.6m for your width then at 2.1 at the eaves and a 1 in 4 slope you'll be looking at pretty close to 2.5 at the pitch.
Crack on!
My old shed was 3.6 x 7.2 with pretty much exactly those heights for the very same reasons.

Where would be the place to order the timber for this sort of construction? And what type? 2x4 for the framing, just plain untreated softwood? Would you need a big frame nailing gun, or screw it together?
I have ordered a 8x 10 wood shed, from a local company, just for storage, as I have so much stuff I need to simply get out of my single car garage before I can even think about doing anything else. It arrives Thursday, coincidentally my 60th birthday. That’s costing me a grand, delivered and assembled.
I need a workshop eventually though as the single car garage will be for storing the hot rod, and I have only walking access to the back yard at present.

i use these for my decking and fencing jobs.
There may be cheaper I am not sure.
I always screw everything together but I would like to purchase a nail gun any excuse! a first fix would be good for me.
As for the timbers I have not had a look yet. 2x2 may be fine for the frame

£30 a sheet for 12 mm structural sheathing ply, not cheap, but not too crazy. Nailed or screwed to 2x4 frames, sounds simple enough.

I built mine from free 2 mtr x 3 mtr pallets, available from most plastic sheet wholesalers and maybe sign makers, they are around 4-5" wide, I used tannalised fence post material around the base and top and as uprights between pallets, slipped 75mm rockwool down the gap, broke some pallets up for extra timber as one side tends to have far fewer slats, I bought trusses from ebay, left over, built to wrong dimensions or design changes, paid very little, broke some up for extra construction timber, used site hording shuttering ply to line the inside or sterling board when I had to buy new, feather edge on the outside, had to buy that new!
you will not regret buying a Paslode lm350 as a cheap first fix gun, 50mm to 90mm mails, the pallets saved money but also made initial construction very quick and that helped keep the project going through the winter of 2017-2018, I had a massive time deadline as my workshop building had been sold and I needed to get all my toys home double quick or throw them away!!!!!! was also very short of cash until completion, a double edged sword, original prefab shed (modified) to the right, dormers open up for easy access to roof space storage,

I got all my timber from my (very) local builders merchants (had an account with them for the best part of 30 years) and I screwed the bulk of mine together using a couple of thousand M6 x 90mm TurboGold screws. There were a hundred or so longer ones here and there, oh, and the featheredge was nailed on with a nail gun (though on reflection I should have used SS screws).
I used treated timber but added copious quantities of creosote to the feather edge.

I'd reccommend 4 x 2 as a minimum for that size of shed. There's a reason Garden Centre sheds don't last!

is a shed ever finished? the right hand up and over has been covered by an 8' square extension in that corner for sandblasting, the front door was a grp up and over 14 foot wide, cut it in half and used it as two opening doors, won't rot and a used 14' up and over was only £20.00, ebay, it helps to have a flatbed truck! I did not want the up and over for two reasons, lets all the heat out, lets noise out, I can open one door to angle any noise escape towards the bottom of the garden in the summer, everything is insulated with 75mm rockwool and it is very easy to heat, just an oil filled rad in the workshop, and you cannot hear a 9" grinder doing it's worst if you are 10 feet away and as my shed is at least 200 feet from the nearest house I can bash away, farm land behind and to the left,
