How do I build a plumb and level garage on a sloped pad???

[builditbackwards]

Does anyone have any experience on how to build a plumb and level garage on a sloped cement pad without cement walls? It's a flat cement pad with no walls and 4" slope over 24'

I'm trying to come up with a solution but am running into issues. The best I can figure, is measuring out each stud to make the top plate level but that is tedious at best, will still cause issues with the siding at the bottom, look strange and be a giant headache.

Any help is greatly appreciated!

If you are talking about fixing a stud wall to a sloped surface then you are about right.

Fix the sole plate all round.

Build the back wall (non sloping) first.

Then find a couple of straight lengths of timber for the (sloping) side header beams. These can then be fixed level. One end fix to the back wall and onto a single (propped) upright at the other. Then you will fill in measuring each individual stud.

Thanks noseall! How do you finish the exterior to hide the slope? Your siding and everything will be out by 4" from one side to the other.

Depends what material you intend weathering the structure with.

If it were say render then you would simply slope the beading.

However if you are using say shiplap or tile hanging then you need to form a plinth or a 'skirt' first, allowing this 'skirt' to deal with the slope then fit your first course of weathering material level.
