The Answer: The Architects Bench!
Continuing the discussion from A few station suggestions:
I like your idea better Blyker as it is an alternative to crafting in your inventory vs. changing the way it’s done. An architect bench is an awesome idea by @Grinder, you could craft all building pieces even extra pieces (given there’s room) for future projects, in one bench. Something like this is needed so you don’t have to crawl across the map gathering while carrying walls and rock! I harvested too much rock, but I’m not throwing it away to collect it again. 
You could just deposit resources, craft and return to the job site to build/upgrade after exploring or whatever.
It would be sweet if it would look like some Conan Exiles time period small crane with drawing plans bench with under construction on it somewhere and tools shown on it. It doesn’t need to be huge but at least as big as the improved blacksmiths bench would be nice. Put a thrall (taskmaster, blacksmith, carpenter) in there for speed and we are good to build! Exiles art team can come up with something fantastic for sure.
Looking forward to seeing these UPGRADABLE crafting stations the devs talked about soon too! My carpenter’s bench has no space!
