Timber frame garage build...

[Screech20]

Hey guys.

Im starting to think about the garage, which i want to make a start on in the new year.
This is what we currently have, a poor effort carport.






I'm thinking of going timber frame, as although some might say could work out more, its something i can work with, where fully brick i'd have to pay labour as well as materials.

After a bit of research I understand i cant use timber on the boundary, so i think i'm going to keep and use the wall thats there. The only thing is, it does seem to let moisture in along the bottom in places, what can i do about that?

Down the other side, back and front, I want to build a dwarf wall, not sure how high, maybe 600mm? Then upto 2.5m in timber frame.

How does this sound:
4"x2" for the frame, boarded in 15mm OSB, moister barrier(?) then cladded with either feather edge or shiplap.

On the inside, 100mm insulation and boarded with OSB.


Is there anything else i need to think about?


Its going to be used as a garage & workshop for me to work on classic Minis, so i need it to be as weather tight as poss.


I'm sure i've missed a few points but hopefully this should get me going.


Cheers

If you only build a dwarf wall, how do you propose anchoring this timber structure down?

I was thinking frame fixing the 2x4 down into the wall, but thats why i'm here for advice.

Sounds plausible to me, provided a DPM is involved.

What other ways could it be done?

I've seen lots of buildings built off a dwarf wall, and in my research, people asking about timber buildings, get advised to do 2 courses of bricks first to get the wood off the ground...

It's how I built my timber-framed porch, more or less - footings, two brick courses, DPM, one more brick course, studwork sole plate fixed into top course. I did the extra course to avoid fixing through the DPM, but I don't know how critical that is.

Sounds good to me. There will be a DPC, within 150mm from the ground level.

I've been thinking about using 3 x 2 now. Otherwise, with the frame, board, batton then whatever goes on last, it'll end up hanging over the brick by quite a lot...?

I don't think that really matters. I used 4x2 for my porch, clad in OSB, then building paper, then battens, then cedar cladding. 3x2 is bit flimsy.
