I am building a garage at the moment and was toying with the idea of adding on a lean-to on one side. What would be the easiest way to do this to avoid problems with settling, apart from not doing it of course! Garage is 3m to the eaves, 8mx5m built with Sitka mean diameter 14", Post and purlin gable. Suggestions please...

Thanks

Alan

Tim, don't worry about the maths, I don't!

What about the question of how to add on a lean to on the side of a building. Surely it cant be that difficult that nobody has done one before?

You built with Sitka spruce? OMG, you must be building the Taj Majhol.j/k.
Sitka lumber sells between $4k-5k per 1000fbm here.
Could you be more specific on the problem?
No different than adding a porch.Vertical support posts will need settling jacks.Allow 3/4" per foot.
There is several methods to attach, (hence noone responded)

You have the option of keeping the same pitch as the main roof or possibly lowering the pitch to gain headroom at the support beam.
You could support the rafters on top of the existing log wall (simplest method) or drop it below the soffit, depending on your preference.
If ceiling height is a concern,keep the beam the same height as the garage,then intersect a roof.
This looks better than lean-to roofs and waaaay more fun to build!Brush up on trigonometry and get "roof framing" by Marshall Gross.Do this correctly and you earned a Phd. in carpentry.:D

Hey Alan!
I got my eagle tong built!
Went 4' long using 1"4540 HTSR shaft (heat treated stress relieved)It's threadable and tough,you can't weld it unless you really know what your doing though. The whole thing bolts together with grade 8 bolts.Only thing I had to weld was the 4 pads.
It cost me about $650 -CD- for materials including some wire rope lifting cables/shackles ect....The locking device will be very useful working alone.
