Please add an alternative to Wood for Construction Parts 1

For the construction parts, there is concrete as an alternative to bricks. Now it would be good if you could replace wood in the later game with something else.

perhaps in the future when they add aluminium, it could be turned into beams and replace wood

There is currently no need for this. You can get more wood from the World Map.
Also, adding growable trees was mentioned on the Roadmap that should help in the future.
