You don’t have to recraft them… because you can no longer craft them 
If you look in your inventory menu all the recipes for crafting building pieces are gone.
The game has a completely new construction system (and it’s much better btw)
You need to craft a construction hammer (inventory crafting 20 wood, 5 twine) and equip it.
After that you can open the building menu with “F” and select the piece you want.
You have to have the raw materials (bricks, reinforcements etc) in your inventory and building is instant… there is no crafting time for the pieces. Right-click puts you in delete mode after which left-clicking will delete pieces. Middle-click works as a copy-paste - you look at any existing building piece next to you, click it and then your active hologram piece becomes that one.
