Are you allowed to build with your own ungraded timber?

[smurfen72]

If you have the opportunity to saw your own lumber, this should be a "non-issue."
Then you don't skimp on dimensions but go big with a proper margin.

It's not free lumber just because you have your own forest, and if you want to go a little extra, you need more lumber, and then it's heavy to build with unnecessarily thick lumber, too. I don't think I gain so much by leaving timber for sawing compared to selling the timber and buying lumber; what you gain is less waste and better quality.

Moreover, the cost of framing lumber to build a garage is almost negligible in relation to the total cost, regardless of where you purchase the lumber.

Kallebo. If I interpret you correctly, you can use your own timber, dimension it as if it were C14 rated, and build based on that?

 

[Stefan1972]

there are probably no rules stating that you can do this or that. It is the builder's responsibility to ensure that what is built complies with current regulations. There is hardly anyone standing with a magnifying glass checking classifications on timber if something happens, but IF something happens and someone dies because the roof collapses, you can of course be prosecuted if the building does not meet the standards.

If you want to be sure, as mentioned, you can buy the timber for the load-bearing parts and build the rest from your own timber.

I remember that you can classify home-sawn timber in a low class as long as you sort out clearly bad pieces. However, I can't find the source. If it collapses, then it's likely an issue with the dimensioning or the timber.

The difference in the sizing of roof trusses between using C24, which is visually graded as T2, and ungraded timber Ö-virke is that you roughly save an inch in height. Roof trusses are primarily calculated with regard to acceptable deflection. Walls usually handle the loads unless they are extremely high. Structural timber is sorted by knot size; in T2, no edge knot can be larger than half the width, on the flat side knots at most 1/4 of the width, decay, and bark shakes are excluded.
