Some buildings does not appeared in build menu

I acquired blocks, boards and braches from the tree, found some strings, crafted some yarn but Loom does not appeared in buildings menu.

The same thing with Compost Bin.

Boards and blocks acquired from tree logs, bone glue crafted in cauldron.

I do something wrong?
Or these buildings required something else?

Thanks in advance

For Loom you need Basic Mechanics, the Compost Bin requires Carpentry and Farming.

Yes, I already have all of these skills.

By found, do you mean foraged or found in someone's loose crate? You need several of each of the items, so best suggestion is to make sure you discovered them. Also dig through menus to make sure you didn't overlook them

I foraged ton of strings (Spindly Taproot and Stinging Nettle) across the my area, chopped several trees and acquired boards and blocks from them.
Wool gained from animals using clover. Yarn crafted on spinning wheel.

My fail.

I am looking again in the skills - not learned Metal Working and Basic Mechanics.

Thanks for helping!
