"Mjösa Tower (Mjøstårnet) is an 85.4m-tall mixed-use timber building located in Brumunddal, Norway. It is the third-tallest building in the country and was recognized as the world’s tallest timber tower by the Council on Tall Buildings and Urban Habitat (CTBUH)."

We can barely do 10m without it falling apart in-game.

Did you note articles materials for building there?

"Materials used in Mjosa Tower
Sustainable wooden materials are used in the construction of both the structure and facade of the Mjøstårnet skyscraper. The building contains 2,600m³ of timber structures.

The decks on the floors two to 11 are made of prefabricated wood components, while the decks on the next seven floors are built using 300mm concrete to improve the strength of the building.

The intermediate flooring between all the levels is built using light, environment-friendly Kerto-Q LVL (laminated veneer lumber) cross-bonded veneer panels, which gives improved load-bearing capacity.

The internal columns, beams, and diagonals of the building are formed by planing and gluing large-scale glued laminated timber (glulam) that is pliable and fire-resistant. Cross-laminated timber (CLT) material was used for the inner walls, elevator shafts, balconies, and stairs.

The envelope of the building is formed by integrating large prefabricated facade elements. Large-scale glulam trusses are arranged along the facades to withstand loads. Steel plates and dowels are used to connect all glulam elements of the tower."

In Valheim terms this would be iron beam, stone, and timber. Not solely timber.

You pretty much supported what we've been saying in this thread concerning the structure rules used here.
