Query on timber sizing - and converting imperial to metric.

You will be fine with the smaller stuff if it's just a storage shed. Personally I would use 4*2 because I always over engineer my own garden buildings and insulate them. It gives extra strength, rigidity and durability - at a cost, but it means that attaching workbenches and heavy stuff is no problem and means you can stand on the roof without it flexing.
 
I understood from your other post that the whole shed will be 16' x 14' with a pent roof which is 7'2" at the highest point. IMHO, that is a substantial shed and, therefore, I would be using timber larger than 47 x 47.

Use whatever you want but IMHO 47 x 47 would be too small for a shed this size.
 
Apologies - must have had a blond moment! 8x 16...

Still reckon that, at that size, you would be better off with larger timber. However, it all depends on the construction method. Bear in mind that it's not always cost-effective to use smaller timber if you end up having to use more of it. It can actually be cheaper to use larger timber in the long run.

Like ntb, I would rather use the bigger timber for a more rigid frame but, at the end of the day, it's your project (and money!) If you are tempted then use something sized 'in between'.
 
Well I'm in the process of doing a sketchup of how I'm planning to build it (mainly so I can cost it out).

Once done I'll post it for criticism ;)

Noted - I do not plan to insulate or anything like that, it's just going to be a basic (but larger) shed.

I have posted my plans - to try and keep on topic, they are in the other thread...

Take a look, comment (but don't kill me ;))

Just had a look at your sketch.
Two comments why the half lap joints,? Just butt them together and nail. Much quicker and more than adequate for a shed
Split level floor, not for me, I would just make a timber frame similar to the shed sides, pack it up off the floor and cover with floorboards or chipboard . If you can afford wpb ply is better.
Just remembered not neccessary to have corner post bigger use same all round, ie 3x2 sawn or 75x50 metric.
Lintol not required just use normal timber at head of door casing to carry boarding.

I agree butt joints are simpler, and I may go down that route come the finish, but I do like good solid joints and the half laps help with the alignment, especially as I will be doing most of this myself.

The split level is because I really do need the internal height.

Other than that, is it OK.

Not sure what you mean about alignment, if all your posts are cut square the frames will be just as square as using half laps. Probably more so as less to go wrong.
Your timber merchant will cut them to length if you ask. Job half done.
Re the split level floor unless your roof is split level I can't see the benefit.

Because the 20cm gained in height allows me to store some extra long stuff I have.

If I split level the roof I lose the the height advantage gained.
