Hello to all the wise and helpful ones!
We are planning to build a carport over a byssja (container, mannskapsbod) and space for 3 cars.
We have sketched a bit and want to make this construction as cheaply as possible.
The carport is intended to be 10 meters long and 8 meters wide, and ideally, we want support only along the long sides (no posts in the middle).
We have looked at roof trusses made by a supplier and are considering ready-made trusses.
Our questions now are: does the top plate need to go around the entire construction, or is it enough to have a stronger beam along the long sides and let the truss hold the construction together?
Approximately what dimensions should be used for posts and beams? (We want to keep costs low and build with wood, but going up a few dimensions for safety is completely fine)
The byssja will probably not be used to support anything since we have no idea about its manufacturer or what it can handle. Does anyone know where we can get information about such things? It has loops for crane lifting (will attach a picture soon).
We are very grateful for your answers! Once we have proper sketches, we will both apply for building permits and consult a professional to ensure it's done right. But any help in the beginning to get good drawings is extremely appreciated

Truss roofs are necessary with the large span, and it's not something you should do yourself if you're not knowledgeable. The major challenge is making the structure stable when it completely lacks exterior walls and the shed is not meant to be load-bearing. The two long sides and the far gable side need stabilization. This can be achieved through diagonal braces, cable crosses, or by covering parts of them with sheathing. A collar beam around helps to stiffen the structure as well. The dimensions of the posts are not a major issue. Ideally, laminated timber 90x90 mm, but even 95x95 with ordinary timber will work regardless of where in Västra Götaland you live.
I order the trusses from a company.
We were thinking of making a trellis on one long side so it could stabilize on one side, the other should preferably be open.
Thank you for your reply

A trellis needs diagonals to be stable. Read the neighboring thread "Hur fästa strävor på bästa sätt" under "Byggmaterial och byggteknik".
