Unable to bring up Construction Menu

[ArEsTus]

Hello, I have bought the game when the autmn sale was happening on steam and I have not once been able to actually enter the construction mode. Nor have I been able to crouch. But I press Space and nothing happens. I notice even in the original startup menu there is no construction mode option nor a (space) input

That would be because as of now, to construct something you need a construction bench, which is a craftable item. To use the layers, you have to create an advanced construction bench.
